0c736c7295 Enforce HTTPS for all downloads to eliminate security vulnerabilities
- Convert 16 HTTP URLs to HTTPS across 3 critical scripts
- Dell OMSA script: Ubuntu archive and Dell repository URLs now use HTTPS
- Proxmox legacy script: Download URLs converted to secure connections
- SSL stack script: Apache source URLs updated to official archive
- Update documentation to reflect resolved security issues
- Mark HTTPS enforcement as completed in todo lists

This addresses the second critical security concern from the security review,
eliminating man-in-the-middle attack vectors during package downloads.

# TSYS FetchApply Testing Framework
## Overview
This testing framework provides comprehensive validation for the TSYS FetchApply infrastructure provisioning system. It includes unit tests, integration tests, security tests, and system validation.
## Test Categories
### 1. Unit Tests (`unit/`)
- **Purpose:** Test individual framework functions and components
- **Scope:** Framework includes, helper functions, syntax validation
- **Example:** `framework-functions.sh` - Tests logging, pretty print, and error handling functions
### 2. Integration Tests (`integration/`)
- **Purpose:** Test complete workflows and module interactions
- **Scope:** End-to-end deployment scenarios, module integration
- **Future:** Module interaction testing, deployment workflow validation
### 3. Security Tests (`security/`)
- **Purpose:** Validate security configurations and practices
- **Scope:** HTTPS enforcement, deployment security, SSH hardening
- **Example:** `https-enforcement.sh` - Validates all URLs use HTTPS
### 4. Validation Tests (`validation/`)
- **Purpose:** System compatibility and pre-flight checks
- **Scope:** System requirements, network connectivity, permissions
- **Example:** `system-requirements.sh` - Validates minimum system requirements
## Usage
### Run All Tests
```bash
./Project-Tests/run-tests.sh
```
### Run Specific Test Categories
```bash
./Project-Tests/run-tests.sh unit # Unit tests only
./Project-Tests/run-tests.sh integration # Integration tests only
./Project-Tests/run-tests.sh security # Security tests only
./Project-Tests/run-tests.sh validation # Validation tests only
```
### Run Individual Tests
```bash
./Project-Tests/validation/system-requirements.sh
./Project-Tests/security/https-enforcement.sh
./Project-Tests/unit/framework-functions.sh
```
## Test Results
- **Console Output:** Real-time test results with color-coded status
- **JSON Reports:** Detailed test reports saved to `logs/tests/`
- **Exit Codes:** 0 for success, 1 for failures
## Configuration Validation
The validation framework performs pre-flight checks to ensure system compatibility:
### System Requirements
- **Memory:** Minimum 2GB RAM
- **Disk Space:** Minimum 10GB available
- **OS Compatibility:** Ubuntu/Debian (tested), others (may work)
### Network Connectivity
- Tests connection to required download sources
- Validates HTTPS endpoints are accessible
- Checks for firewall/proxy issues
### Command Dependencies
- Verifies required tools are installed (`curl`, `wget`, `git`, `systemctl`, `apt-get`)
- Checks for proper versions where applicable
### Permissions
- Validates write access to system directories
- Checks for required administrative privileges
## Adding New Tests
### Test File Structure
```bash
#!/bin/bash
set -euo pipefail
function test_something() {
echo "🔍 Testing something..."
if [[ condition ]]; then
echo "✅ Test passed"
return 0
else
echo "❌ Test failed"
return 1
fi
}
function main() {
echo "🧪 Running Test Suite Name"
echo "=========================="
local total_failures=0
test_something || ((total_failures++))
echo "=========================="
if [[ $total_failures -eq 0 ]]; then
echo "✅ All tests passed"
exit 0
else
echo "❌ $total_failures tests failed"
exit 1
fi
}
if [[ "${BASH_SOURCE[0]}" == "${0}" ]]; then
main "$@"
fi
```
### Test Categories Guidelines
- **Unit Tests:** Focus on individual functions, fast execution
- **Integration Tests:** Test module interactions, longer execution
- **Security Tests:** Validate security configurations
- **Validation Tests:** Pre-flight system checks
## Continuous Integration
The testing framework is designed to integrate with CI/CD pipelines:
```bash
# Example CI script
./Project-Tests/run-tests.sh all
test_exit_code=$?
if [[ $test_exit_code -eq 0 ]]; then
echo "All tests passed - deployment approved"
else
echo "Tests failed - deployment blocked"
exit 1
fi
```
## Test Development Best Practices
1. **Clear Test Names:** Use descriptive function names
2. **Proper Exit Codes:** Return 0 for success, 1 for failure
3. **Informative Output:** Use emoji and clear messages
4. **Timeout Protection:** Use timeout for network operations
5. **Cleanup:** Remove temporary files and resources
6. **Error Handling:** Use `set -euo pipefail` for strict error handling
## Troubleshooting
### Common Issues
- **Permission Denied:** Run tests with appropriate privileges
- **Network Timeouts:** Check firewall and proxy settings
- **Missing Dependencies:** Install required tools before testing
- **Script Errors:** Validate syntax with `bash -n script.sh`
### Debug Mode
```bash
# Enable debug output
export DEBUG=1
./Project-Tests/run-tests.sh
```
## Contributing
When adding new functionality to FetchApply:
1. Add corresponding tests in appropriate category
2. Run full test suite before committing
3. Update documentation for new test cases
4. Ensure tests pass in clean environment

# TSYS FetchApply Code Review Findings
**Review Date:** July 14, 2025
**Reviewer:** Claude (Anthropic)
**Repository:** TSYS Group Infrastructure Provisioning Scripts
## Executive Summary
The repository shows good architectural structure with centralized framework components, but has several performance, security, and maintainability issues that require attention. The codebase is functional but needs optimization for production reliability.
## Critical Issues (High Priority)
### 1. Package Installation Performance ⚠️
**Location:** `ProjectCode/SetupNewSystem.sh:27` and `Lines 117-183`
**Issue:** Multiple separate package installation commands causing performance bottlenecks
```bash
# Current inefficient pattern
apt-get -y install git sudo dmidecode curl
# ... later in script ...
DEBIAN_FRONTEND="noninteractive" apt-get -qq --yes install virt-what auditd ...
```
**Impact:** Significantly slower deployment, multiple package cache updates
**Fix:** Combine all package installations into single command
### 2. Network Operations Lack Error Handling 🔴
**Location:** `ProjectCode/SetupNewSystem.sh:61-63`, multiple modules
**Issue:** curl commands without timeout or error handling
```bash
# Vulnerable pattern
curl --silent ${DL_ROOT}/path/file >/etc/config
```
**Impact:** Deployment failures in poor network conditions
**Fix:** Add timeout, error handling, and retry logic
### 3. Unquoted Variable Expansions 🔴
**Location:** Multiple files, including `ProjectCode/SetupNewSystem.sh:244`
**Issue:** Variables used without proper quoting creating security risks
```bash
# Risky pattern
chsh -s $(which zsh) root
```
**Impact:** Potential command injection, script failures
**Fix:** Quote all variable expansions consistently
## Security Concerns
### 4. No Download Integrity Verification 🔴
**Issue:** All remote downloads lack checksum verification
**Impact:** Supply chain attack vulnerability
**Recommendation:** Implement SHA256 checksum validation
### 5. Excessive Root Privilege Usage ⚠️
**Issue:** All operations run as root without privilege separation
**Impact:** Unnecessary security exposure
**Recommendation:** Delegate non-privileged operations when possible
## Performance Optimization Opportunities
### 6. Individual File Downloads 🟡
**Location:** `ProjectCode/Modules/Security/secharden-scap-stig.sh:66-77`
**Issue:** 12+ individual curl commands for config files
```bash
curl --silent ${DL_ROOT}/path1 > /etc/file1
curl --silent ${DL_ROOT}/path2 > /etc/file2
# ... repeated 12+ times
```
**Impact:** Network overhead, slower deployment
**Fix:** Batch download operations
### 7. Missing Connection Pooling ⚠️
**Issue:** No connection reuse for multiple downloads from same host
**Impact:** Unnecessary connection overhead
**Fix:** Use curl with connection reuse or wget with keep-alive
## Code Quality Issues
### 8. Inconsistent Framework Usage 🟡
**Issue:** Not all modules use established error handling framework
**Impact:** Inconsistent error reporting, debugging difficulties
**Fix:** Standardize framework usage across all modules
### 9. Incomplete Function Implementations 🟡
**Location:** `Framework-Includes/LookupKv.sh`
**Issue:** Stubbed functions with no implementation
**Impact:** Technical debt, confusion
**Fix:** Implement or remove unused functions
### 10. Missing Input Validation 🟡
**Location:** `Project-Includes/pi-detect.sh`
**Issue:** Functions lack proper input validation and quoting
**Impact:** Potential script failures
**Fix:** Add comprehensive input validation
## Recommended Immediate Actions
### Phase 1: Critical Fixes (Week 1)
1. **Fix variable quoting** throughout codebase
2. **Add error handling** to all network operations
3. **Combine package installations** for performance
4. **Implement download integrity verification**
### Phase 2: Performance Optimization (Week 2)
1. **Batch file download operations**
2. **Add connection timeouts and retries**
3. **Implement bulk configuration deployment**
4. **Optimize service restart procedures**
### Phase 3: Code Quality (Week 3-4)
1. **Standardize framework usage**
2. **Add comprehensive input validation**
3. **Implement proper logging with timestamps**
4. **Remove or complete stubbed functions**
## Specific Code Improvements
### Enhanced Error Handling Pattern
```bash
function safe_download() {
local url="$1"
local dest="$2"
local max_attempts=3
local attempt=1
while [[ $attempt -le $max_attempts ]]; do
if curl --silent --connect-timeout 30 --max-time 60 --fail "$url" > "$dest"; then
print_success "Downloaded: $(basename "$dest")"
return 0
else
print_warning "Download attempt $attempt failed: $url"
((attempt++))
sleep 5
fi
done
print_error "Failed to download after $max_attempts attempts: $url"
return 1
}
```
### Bulk Package Installation Pattern
```bash
function install_all_packages() {
print_info "Installing all required packages..."
local packages=(
# Core system packages
git sudo dmidecode curl wget
# Security packages
auditd fail2ban aide
# Monitoring packages
snmpd snmp-mibs-downloader
# Additional packages
virt-what net-tools htop
)
if DEBIAN_FRONTEND="noninteractive" apt-get -qq --yes -o Dpkg::Options::="--force-confold" install "${packages[@]}"; then
print_success "All packages installed successfully"
else
print_error "Package installation failed"
return 1
fi
}
```
### Batch Configuration Download
```bash
function download_configurations() {
print_info "Downloading configuration files..."
local -A configs=(
["${DL_ROOT}/ProjectCode/ConfigFiles/ZSH/tsys-zshrc"]="/etc/zshrc"
["${DL_ROOT}/ProjectCode/ConfigFiles/SMTP/aliases"]="/etc/aliases"
["${DL_ROOT}/ProjectCode/ConfigFiles/Syslog/rsyslog.conf"]="/etc/rsyslog.conf"
)
for url in "${!configs[@]}"; do
local dest="${configs[$url]}"
if ! safe_download "$url" "$dest"; then
return 1
fi
done
print_success "All configurations downloaded"
}
```
## Testing Recommendations
### Add Performance Tests
```bash
function test_package_installation_performance() {
local start_time=$(date +%s)
install_all_packages
local end_time=$(date +%s)
local duration=$((end_time - start_time))
echo "✅ Package installation completed in ${duration}s"
if [[ $duration -gt 300 ]]; then
echo "⚠️ Installation took longer than expected (>5 minutes)"
fi
}
```
### Add Network Resilience Tests
```bash
function test_network_error_handling() {
# Test with invalid URL
if safe_download "https://invalid.example.com/file" "/tmp/test"; then
echo "❌ Error handling test failed - should have failed"
return 1
else
echo "✅ Error handling test passed"
return 0
fi
}
```
## Monitoring and Metrics
### Deployment Performance Metrics
- **Package installation time:** Should complete in <5 minutes
- **Configuration download time:** Should complete in <2 minutes
- **Service restart time:** Should complete in <30 seconds
- **Total deployment time:** Should complete in <15 minutes
### Error Rate Monitoring
- **Network operation failures:** Should be <1%
- **Package installation failures:** Should be <0.1%
- **Service restart failures:** Should be <0.1%
## Compliance Assessment
### Development Guidelines Adherence
**Good:** Single package commands in newer modules
**Good:** Framework integration patterns
**Good:** Function documentation in recent code
**Needs Work:** Variable quoting consistency
**Needs Work:** Error handling standardization
**Needs Work:** Input validation coverage
## Risk Assessment
**Current Risk Level:** Medium
**Key Risks:**
1. **Deployment failures** due to network issues
2. **Security vulnerabilities** from unvalidated downloads
3. **Performance issues** in production deployments
4. **Maintenance challenges** from code inconsistencies
**Mitigation Priority:**
1. Network error handling (High)
2. Download integrity verification (High)
3. Performance optimization (Medium)

# Claude Code Review - TSYS FetchApply Infrastructure
**Review Date:** July 14, 2025 (Updated)
**Reviewed by:** Claude (Anthropic)
**Repository:** TSYS Group Infrastructure Provisioning Scripts
**Previous Review:** July 12, 2025
## Project Overview
This repository contains infrastructure-as-code for provisioning Linux servers in the TSYS Group environment. The codebase includes 32 shell scripts (~2,800 lines) organized into a modular framework for system hardening, security configuration, and operational tooling deployment.
## Strengths ✅
### Security Hardening
- **SSH Security:** Comprehensive SSH hardening with key-only authentication, disabled password login, and secure cipher configurations
- **Security Agents:** Automated deployment of Wazuh SIEM agents, audit tools, and SCAP-STIG compliance checking
- **File Permissions:** Proper restrictive permissions (400 for SSH keys, 644 for configs)
- **Network Security:** Firewall configuration, network discovery tools (LLDP), and monitoring agents
### Code Quality
- **Error Handling:** Robust bash strict mode implementation (`set -euo pipefail`) with custom error trapping and line number reporting
- **Modular Design:** Well-organized structure separating framework components, configuration files, and functional modules
- **Environment Awareness:** Intelligent detection of physical vs virtual hosts, distribution-specific logic, and hardware-specific optimizations
- **Logging:** Centralized logging with timestamp-based log files and colored output for debugging
### Operational Excellence
- **Package Management:** Automated repository setup for security tools (Lynis, Webmin, Tailscale, Wazuh)
- **System Tuning:** Performance optimizations for physical hosts, virtualization-aware configurations
- **Monitoring Integration:** LibreNMS agents, SNMP configuration, and system metrics collection
## Security Concerns ⚠️
### Critical Issues
1. **~~Insecure Deployment Method~~** ✅ **RESOLVED:** Now uses `git clone` + local script execution instead of `curl | bash`
2. **No Integrity Verification:** Downloaded scripts lack checksum validation or cryptographic signatures
3. **~~HTTP Downloads~~** ✅ **RESOLVED:** All HTTP URLs converted to HTTPS (Dell OMSA, Proxmox, Apache sources)
### Moderate Risks
4. **Exposed SSH Keys:** Public SSH keys committed directly to repository without rotation mechanism
5. **Hard-coded Credentials:** Server hostnames and domain names embedded in scripts
6. **Missing Secrets Management:** No current implementation of Bitwarden/Vault integration (noted in TODO comments)
## Improvement Recommendations 🔧
### High Priority (Security Critical)
1. **~~Secure Deployment Pipeline~~** ✅ **RESOLVED:** Now uses git clone-based deployment
2. **~~HTTPS Enforcement~~** ✅ **RESOLVED:** All HTTP downloads converted to HTTPS
3. **Script Integrity:** Implement SHA256 checksum verification for all downloaded components
4. **Secrets Management:** Deploy proper secrets handling for SSH keys and sensitive configurations
### Medium Priority (Operational)
5. **Testing Framework:** Add integration tests for provisioning workflows
6. **Documentation Enhancement:** Expand security considerations and deployment procedures
7. **Configuration Validation:** Add pre-deployment validation of system requirements
8. **Rollback Capability:** Implement configuration backup and rollback mechanisms
### Low Priority (Quality of Life)
9. **Error Recovery:** Enhanced error recovery and partial deployment resumption
10. **Monitoring Integration:** Centralized logging and deployment status reporting
11. **User Interface:** Consider web-based deployment dashboard for non-technical users
## Risk Assessment 📊
**Overall Risk Level:** Low-Medium ⬇️ (Reduced from Medium-Low)
The repository contains well-architected defensive security tools with strong error handling and modular design. **Major security improvement:** The insecure `curl | bash` deployment method has been replaced with git-based deployment. Remaining concerns are primarily around hardening the provisioning scripts themselves rather than the deployment method.
**Recommendation:** Continue addressing remaining security issues (HTTPS enforcement, secrets management) but the critical deployment risk has been mitigated. The codebase is much safer for production use.
## Update Summary (July 14, 2025)
**✅ Resolved Issues:**
- Insecure deployment method replaced with git clone approach
- README.md updated with project management and community links
- Deployment security risk significantly reduced
- All HTTP URLs converted to HTTPS (Dell OMSA, Proxmox, Apache sources)
**🔄 Remaining Priorities:**
1. ~~HTTPS enforcement for internal downloads~~**RESOLVED:** All HTTP URLs converted to HTTPS
2. Secrets management implementation
3. Script integrity verification
4. SSH key rotation from repository
## Files Reviewed
- 32 shell scripts across Framework-Includes, Project-Includes, and ProjectCode directories
- Configuration files for SSH, SNMP, logging, and system services
- Security modules for hardening, authentication, and monitoring
- Documentation and framework configuration files
## Next Steps
See `charles-todo.md` and `claude-todo.md` for detailed action items prioritized for human operators and AI assistants respectively.

# TSYS FetchApply Development Guidelines
## Overview
This document contains development standards and best practices for the TSYS FetchApply infrastructure provisioning system.
## Package Management Best Practices
### Combine apt-get Install Commands
**Rule:** Always combine multiple package installations into a single `apt-get install` command for performance.
**Rationale:** Single command execution is significantly faster than multiple separate commands due to:
- Reduced package cache processing
- Single dependency resolution
- Fewer network connections
- Optimized package download ordering
#### ✅ Correct Implementation
```bash
# Install all packages in one command
apt-get install -y package1 package2 package3 package4
# Real example from 2FA script
apt-get install -y libpam-google-authenticator qrencode
```
#### ❌ Incorrect Implementation
```bash
# Don't use separate commands for each package
apt-get install -y package1
apt-get install -y package2
apt-get install -y package3
```
#### Complex Package Installation Pattern
```bash
function install_security_packages() {
print_info "Installing security packages..."
# Update package cache once
apt-get update
# Install all packages in single command
apt-get install -y \
auditd \
fail2ban \
libpam-google-authenticator \
lynis \
rkhunter \
aide \
chkrootkit \
clamav \
clamav-daemon
print_success "Security packages installed successfully"
}
```
## Script Development Standards
### Error Handling
- Always use `set -euo pipefail` at script start
- Implement proper error trapping
- Use framework error handling functions
- Return appropriate exit codes
### Function Structure
```bash
function function_name() {
print_info "Description of what function does..."
# Local variables
local var1="value"
local var2="value"
# Function logic
if [[ condition ]]; then
print_success "Success message"
return 0
else
print_error "Error message"
return 1
fi
}
```
### Framework Integration
- Source framework includes at script start
- Use framework logging and pretty print functions
- Follow existing patterns for consistency
- Include proper PROJECT_ROOT path resolution
```bash
# Standard framework sourcing pattern
PROJECT_ROOT="$(dirname "$(realpath "${BASH_SOURCE[0]}")")/../.."
source "$PROJECT_ROOT/Framework-Includes/PrettyPrint.sh"
source "$PROJECT_ROOT/Framework-Includes/Logging.sh"
source "$PROJECT_ROOT/Framework-Includes/ErrorHandling.sh"
```
## Code Quality Standards
### ShellCheck Compliance
- All scripts must pass shellcheck validation
- Address shellcheck warnings appropriately
- Use proper quoting for variables
- Handle edge cases and error conditions
### Variable Naming
- Use UPPERCASE for global constants
- Use lowercase for local variables
- Use descriptive names
- Quote all variable expansions
```bash
# Global constants
declare -g BACKUP_DIR="/root/backup"
declare -g CONFIG_FILE="/etc/ssh/sshd_config"
# Local variables
local user_name="localuser"
local temp_file="/tmp/config.tmp"
# Proper quoting
if [[ -f "$CONFIG_FILE" ]]; then
cp "$CONFIG_FILE" "$BACKUP_DIR/"
fi
```
### Function Documentation
- Include purpose description
- Document parameters if any
- Document return values
- Include usage examples for complex functions
```bash
# Configure SSH hardening settings
# Parameters: none
# Returns: 0 on success, 1 on failure
# Usage: configure_ssh_hardening
function configure_ssh_hardening() {
print_info "Configuring SSH hardening..."
# Implementation
}
```
## Testing Requirements
### Test Coverage
- Every new module must include corresponding tests
- Test both success and failure scenarios
- Validate configurations after changes
- Include integration tests for complex workflows
### Test Categories
1. **Unit Tests:** Individual function validation
2. **Integration Tests:** Module interaction testing
3. **Security Tests:** Security configuration validation
4. **Validation Tests:** System requirement checking
### Test Implementation Pattern
```bash
function test_function_name() {
echo "🔍 Testing specific functionality..."
local failed=0
# Test implementation
if [[ condition ]]; then
echo "✅ Test passed"
else
echo "❌ Test failed"
((failed++))
fi
return $failed
}
```
## Security Standards
### Configuration Backup
- Always backup configurations before modification
- Use timestamped backup directories
- Provide restore instructions
- Test backup/restore procedures
### Service Management
- Test configurations before restarting services
- Provide rollback procedures
- Validate service status after changes
- Include service dependency handling
### User Safety
- Use `nullok` for gradual 2FA rollout
- Provide clear setup instructions
- Include emergency access procedures
- Test all access methods before enforcement
## Documentation Standards
### Script Headers
```bash
#!/bin/bash
# TSYS Module Name - Brief Description
# Longer description of what this script does
# Author: TSYS Development Team
# Version: 1.0
# Last Updated: YYYY-MM-DD
set -euo pipefail
```
### Inline Documentation
- Comment complex logic
- Explain non-obvious decisions
- Document external dependencies
- Include troubleshooting notes
### User Documentation
- Create comprehensive guides for complex features
- Include step-by-step procedures
- Provide troubleshooting sections
- Include examples and use cases
## Performance Optimization
### Package Management
- Single apt-get commands (as noted above)
- Cache package lists appropriately
- Use specific package versions when stability required
- Clean up package cache when appropriate
### Network Operations
- Use connection timeouts for external requests
- Implement retry logic with backoff
- Cache downloaded resources when possible
- Validate download integrity
### File Operations
- Use efficient file processing tools
- Minimize file system operations
- Use appropriate file permissions

## Version Control Practices
### Commit Messages
- Use descriptive commit messages
- Include scope of changes
- Reference related issues/requirements
- Follow established commit message format
### Branch Management
- Test changes in feature branches
- Use pull requests for review
- Maintain clean commit history
- Tag releases appropriately
### Code Review Requirements
- All changes require review
- Security changes require security team review
- Test coverage must be maintained
- Documentation must be updated
## Deployment Practices
### Pre-Deployment
- Run full test suite
- Validate in test environment
- Review security implications
- Update documentation
### Deployment Process
- Use configuration validation
- Implement gradual rollout when possible
- Monitor for issues during deployment
- Have rollback procedures ready

# Create backup directory
mkdir -p "$BACKUP_DIR"
print_header "TSYS Module Template"
function backup_configs() {
print_info "Creating configuration backup..."
if [[ -f "$CONFIG_FILE" ]]; then
cp "$CONFIG_FILE" "$BACKUP_DIR/"
print_success "Configuration backed up"
fi
}
function install_packages() {
print_info "Installing required packages..."
# Update package cache
apt-get update
# Install all packages in single command
apt-get install -y package1 package2 package3
print_success "Packages installed successfully"
}
function configure_module() {
print_info "Configuring module..."
# Configuration logic here
print_success "Module configured successfully"
}
function validate_configuration() {
print_info "Validating configuration..."
local failed=0
# Validation logic here
if [[ $failed -eq 0 ]]; then
print_success "Configuration validation passed"
return 0
else
print_error "Configuration validation failed"
return 1
fi
}
function main() {
# Check if running as root
if [[ $EUID -ne 0 ]]; then
print_error "This script must be run as root"
exit 1
fi

# Code Refactoring Examples
This document provides specific examples of how to apply the code review findings to improve performance, security, and reliability.
## Package Installation Optimization
### Before (Current - Multiple Commands)
```bash
# Line 27 in SetupNewSystem.sh
apt-get -y install git sudo dmidecode curl
# Lines 117-183 (later in script)
DEBIAN_FRONTEND="noninteractive" apt-get -qq --yes -o Dpkg::Options::="--force-confold" install \
virt-what \
auditd \
aide \
# ... many more packages
```
### After (Optimized - Single Command)
```bash
function install_all_packages() {
print_info "Installing all required packages..."
# All packages in logical groups for better readability
local packages=(
# Core system tools
git sudo dmidecode curl wget net-tools htop
# Security and auditing
auditd aide fail2ban lynis rkhunter
# Monitoring and SNMP
snmpd snmp-mibs-downloader libsnmp-dev
# Virtualization detection
virt-what
# System utilities
rsyslog logrotate ntp ntpdate
cockpit cockpit-ws cockpit-system
# Development and debugging
build-essential dkms
# Network services
openssh-server ufw
)
# Single package installation command with retry logic
local max_attempts=3
local attempt=1
while [[ $attempt -le $max_attempts ]]; do
if DEBIAN_FRONTEND="noninteractive" apt-get -qq --yes -o Dpkg::Options::="--force-confold" install "${packages[@]}"; then
print_success "All packages installed successfully"
return 0
else
print_warning "Package installation attempt $attempt failed"
if [[ $attempt -lt $max_attempts ]]; then
print_info "Retrying in 10 seconds..."
sleep 10
apt-get update # Refresh package cache before retry
fi
((attempt++))
fi
done
print_error "Package installation failed after $max_attempts attempts"
return 1
}
```
## Safe Download Implementation
### Before (Current - Unsafe Downloads)
```bash
# Lines 61-63 in SetupNewSystem.sh
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/ZSH/tsys-zshrc >/etc/zshrc
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/SMTP/aliases >/etc/aliases
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/Syslog/rsyslog.conf >/etc/rsyslog.conf
```
### After (Safe Downloads with Error Handling)
```bash
function download_system_configs() {
print_info "Downloading system configuration files..."
# Source the safe download framework
source "$PROJECT_ROOT/Framework-Includes/SafeDownload.sh"
# Define configuration downloads with checksums (optional)
declare -A config_downloads=(
["${DL_ROOT}/ProjectCode/ConfigFiles/ZSH/tsys-zshrc"]="/etc/zshrc"
["${DL_ROOT}/ProjectCode/ConfigFiles/SMTP/aliases"]="/etc/aliases"
["${DL_ROOT}/ProjectCode/ConfigFiles/Syslog/rsyslog.conf"]="/etc/rsyslog.conf"
["${DL_ROOT}/ProjectCode/ConfigFiles/SSH/Configs/tsys-sshd-config"]="/etc/ssh/sshd_config.tsys"
)
# Validate all URLs are accessible before starting
local urls=()
for url in "${!config_downloads[@]}"; do
urls+=("$url")
done
if ! validate_required_urls "${urls[@]}"; then
print_error "Some configuration URLs are not accessible"
return 1
fi
# Perform batch download with backup
local failed_downloads=0
for url in "${!config_downloads[@]}"; do
local dest="${config_downloads[$url]}"
if ! safe_config_download "$url" "$dest"; then
((failed_downloads++))
fi
done
if [[ $failed_downloads -eq 0 ]]; then
print_success "All configuration files downloaded successfully"
return 0
else
print_error "$failed_downloads configuration downloads failed"
return 1
fi
}
```
## Variable Quoting Fixes
### Before (Unsafe Variable Usage)
```bash
# Line 244 in SetupNewSystem.sh
chsh -s $(which zsh) root
# Multiple instances throughout codebase
if [ -f $CONFIG_FILE ]; then
cp $CONFIG_FILE $BACKUP_DIR
fi
```
### After (Proper Variable Quoting)
```bash
# Safe variable usage with proper quoting
chsh -s "$(which zsh)" root
# Consistent quoting pattern
if [[ -f "$CONFIG_FILE" ]]; then
cp "$CONFIG_FILE" "$BACKUP_DIR/"
fi
# Function parameter handling
function configure_service() {
local service_name="$1"
local config_file="$2"
if [[ -z "$service_name" || -z "$config_file" ]]; then
print_error "configure_service: service name and config file required"
return 1
fi
print_info "Configuring service: $service_name"
# Safe operations with quoted variables
}
```
## Service Management with Error Handling
### Before (Basic Service Operations)
```bash
# Current pattern in various modules
systemctl restart snmpd
systemctl enable snmpd
```
### After (Robust Service Management)
```bash
function safe_service_restart() {
local service="$1"
local config_test_cmd="${2:-}"
if [[ -z "$service" ]]; then
print_error "safe_service_restart: service name required"
return 1
fi
print_info "Managing service: $service"
# Test configuration if test command provided
if [[ -n "$config_test_cmd" ]]; then
print_info "Testing $service configuration..."
if ! eval "$config_test_cmd"; then
print_error "$service configuration test failed"
return 1
fi
print_success "$service configuration test passed"
fi
# Check if service exists
if ! systemctl list-unit-files "$service.service" >/dev/null 2>&1; then
print_error "Service $service does not exist"
return 1
fi
# Stop service if running
if systemctl is-active "$service" >/dev/null 2>&1; then
print_info "Stopping $service..."
if ! systemctl stop "$service"; then
print_error "Failed to stop $service"
return 1
fi
fi
# Start and enable service
print_info "Starting and enabling $service..."
if systemctl start "$service" && systemctl enable "$service"; then
print_success "$service started and enabled successfully"
# Verify service is running
sleep 2
if systemctl is-active "$service" >/dev/null 2>&1; then
print_success "$service is running properly"
return 0
else
print_error "$service failed to start properly"
return 1
fi
else
print_error "Failed to start or enable $service"
return 1
fi
}
# Usage examples
safe_service_restart "sshd" "sshd -t"
safe_service_restart "snmpd"
safe_service_restart "rsyslog"
```
## Batch Configuration Deployment
### Before (Individual File Operations)
```bash
# Lines 66-77 in secharden-scap-stig.sh
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/ModProbe/usb_storage.conf > /etc/modprobe.d/usb_storage.conf
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/ModProbe/dccp.conf > /etc/modprobe.d/dccp.conf
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/ModProbe/rds.conf > /etc/modprobe.d/rds.conf
# ... 12 more individual downloads
```
### After (Batch Operations with Error Handling)
```bash
function deploy_modprobe_configs() {
print_info "Deploying modprobe security configurations..."
source "$PROJECT_ROOT/Framework-Includes/SafeDownload.sh"
local modprobe_configs=(
"usb_storage" "dccp" "rds" "sctp" "tipc"
"cramfs" "freevxfs" "hfs" "hfsplus"
"jffs2" "squashfs" "udf"
)
# Create download map
declare -A config_downloads=()
for config in "${modprobe_configs[@]}"; do
local url="${DL_ROOT}/ProjectCode/ConfigFiles/ModProbe/${config}.conf"
local dest="/etc/modprobe.d/${config}.conf"
config_downloads["$url"]="$dest"
done
# Validate URLs first
local urls=()
for url in "${!config_downloads[@]}"; do
urls+=("$url")
done
if ! validate_required_urls "${urls[@]}"; then
print_error "Some modprobe configuration URLs are not accessible"
return 1
fi
# Perform batch download
if batch_download config_downloads; then
print_success "All modprobe configurations deployed"
# Update initramfs to apply changes
if update-initramfs -u; then
print_success "Initramfs updated with new module configurations"
else
print_warning "Failed to update initramfs - reboot may be required"
fi
return 0
else
print_error "Failed to deploy some modprobe configurations"
return 1
fi
}
```
## Input Validation and Error Handling
### Before (Minimal Validation)
```bash
# pi-detect.sh current implementation
function pi-detect() {
print_info Now running "$FUNCNAME"....
if [ -f /sys/firmware/devicetree/base/model ] ; then
export IS_RASPI="1"
fi
}
```
### After (Comprehensive Validation)
```bash
function pi-detect() {
print_info "Now running $FUNCNAME..."
# Initialize variables with default values
export IS_RASPI="0"
export PI_MODEL=""
export PI_REVISION=""
# Check for Raspberry Pi detection file
local device_tree_model="/sys/firmware/devicetree/base/model"
local cpuinfo_file="/proc/cpuinfo"
if [[ -f "$device_tree_model" ]]; then
# Try device tree method first (most reliable)
local model_info
model_info=$(tr -d '\0' < "$device_tree_model" 2>/dev/null)
if [[ "$model_info" =~ [Rr]aspberry.*[Pp]i ]]; then
export IS_RASPI="1"
export PI_MODEL="$model_info"
print_success "Raspberry Pi detected via device tree: $PI_MODEL"
fi
elif [[ -f "$cpuinfo_file" ]]; then
# Fallback to cpuinfo method
if grep -qi "raspberry" "$cpuinfo_file"; then
export IS_RASPI="1"
PI_MODEL=$(grep "^Model" "$cpuinfo_file" | cut -d: -f2 | sed 's/^[[:space:]]*//' 2>/dev/null || echo "Unknown Pi Model")
PI_REVISION=$(grep "^Revision" "$cpuinfo_file" | cut -d: -f2 | sed 's/^[[:space:]]*//' 2>/dev/null || echo "Unknown")
export PI_MODEL
export PI_REVISION
print_success "Raspberry Pi detected via cpuinfo: $PI_MODEL (Rev: $PI_REVISION)"
fi
fi
if [[ "$IS_RASPI" == "1" ]]; then
print_info "Raspberry Pi specific optimizations will be applied"
else
print_info "Standard x86/x64 system detected"
fi
return 0
}
```
## Function Framework Integration
### Before (Inconsistent Framework Usage)
```bash
# Mixed patterns throughout codebase
function some_function() {
echo "Doing something..."
command_that_might_fail
echo "Done"
}
```
### After (Standardized Framework Integration)
```bash
function some_function() {
print_info "Now running $FUNCNAME..."
# Local variables
local config_file="/etc/example.conf"
local backup_dir="/root/backup"
local failed=0
# Validate prerequisites
if [[ ! -d "$backup_dir" ]]; then
if ! mkdir -p "$backup_dir"; then
print_error "Failed to create backup directory: $backup_dir"
return 1
fi
fi
# Backup existing configuration
if [[ -f "$config_file" ]]; then
if cp "$config_file" "$backup_dir/$(basename "$config_file").bak.$(date +%Y%m%d-%H%M%S)"; then
print_info "Backed up existing configuration"
else
print_error "Failed to backup existing configuration"
return 1
fi
fi
# Perform main operation with error handling
if command_that_might_fail; then
print_success "Operation completed successfully"
else
print_error "Operation failed"
return 1
fi
print_success "Completed $FUNCNAME"
return 0
}
```
## Performance Monitoring Integration
### Enhanced Deployment with Metrics
```bash
function deploy_with_metrics() {
local start_time end_time duration
local operation_name="$1"
shift
local operation_function="$1"
shift
print_info "Starting $operation_name..."
start_time=$(date +%s)
# Execute the operation
if "$operation_function" "$@"; then
end_time=$(date +%s)
duration=$((end_time - start_time))
print_success "$operation_name completed in ${duration}s"
# Log performance metrics
echo "$(date '+%Y-%m-%d %H:%M:%S') - $operation_name: ${duration}s" >> /var/log/fetchapply-performance.log
# Alert if operation took too long
case "$operation_name" in
"Package Installation")
if [[ $duration -gt 300 ]]; then
print_warning "Package installation took longer than expected (${duration}s > 300s)"
fi
;;
"Configuration Download")
if [[ $duration -gt 120 ]]; then
print_warning "Configuration download took longer than expected (${duration}s > 120s)"
fi
;;
esac
return 0
else
end_time=$(date +%s)
duration=$((end_time - start_time))
print_error "$operation_name failed after ${duration}s"
echo "$(date '+%Y-%m-%d %H:%M:%S') - $operation_name: FAILED after ${duration}s" >> /var/log/fetchapply-performance.log
return 1
fi
}
# Usage example
deploy_with_metrics "Package Installation" install_all_packages
deploy_with_metrics "Configuration Download" download_system_configs
deploy_with_metrics "SSH Hardening" configure_ssh_hardening
```
## Testing Integration
### Comprehensive Validation Function

function validate_deployment() {
print_header "Deployment Validation"
local validation_failures=0
# Test package installation
local required_packages=("git" "curl" "wget" "snmpd" "auditd" "fail2ban")

# TSYS Two-Factor Authentication Implementation Guide
## Overview
This guide provides complete instructions for implementing and managing two-factor authentication (2FA) on TSYS servers using Google Authenticator (TOTP).
## What This Implementation Provides
### Services Protected by 2FA
- **SSH Access:** Requires SSH key + 2FA token
- **Cockpit Web Interface:** Requires password + 2FA token
- **Webmin Administration:** Requires password + 2FA token (if installed)
### Security Features
- **Time-based One-Time Passwords (TOTP):** Standard 6-digit codes
- **Backup Codes:** Emergency access codes
- **Gradual Rollout:** Optional nullok mode for phased deployment
- **Configuration Backup:** Automatic backup of all configs
## Implementation Steps
### Step 1: Run the 2FA Setup Script
```bash
# Navigate to the security modules directory
cd ProjectCode/Modules/Security
# Run the 2FA setup script as root
sudo bash secharden-2fa.sh
```
### Step 2: Validate Installation
```bash
# Run 2FA validation tests
./Project-Tests/security/2fa-validation.sh
# Run specific 2FA security test
./Project-Tests/run-tests.sh security
```
### Step 3: Setup Individual Users
For each user that needs 2FA access:
```bash
# Check setup instructions
cat /home/username/2fa-setup-instructions.txt
# Run user setup script
sudo /tmp/setup-2fa-username.sh
```
### Step 4: Test 2FA Access
1. **Test SSH access** from another terminal
2. **Test Cockpit access** via web browser
3. **Test Webmin access** if installed
## User Setup Process
### Installing Authenticator Apps
Users need one of these apps on their phone:
- **Google Authenticator** (Android/iOS)
- **Authy** (Android/iOS)
- **Microsoft Authenticator** (Android/iOS)
- **1Password** (with TOTP support)
### Setting Up 2FA for a User
1. **Run setup script:**
```bash
sudo /tmp/setup-2fa-username.sh
```
2. **Follow prompts:**
- Answer "y" to update time-based token
- Scan QR code with authenticator app
- Save emergency backup codes securely
- Answer "y" to remaining security questions
3. **Test immediately:**
```bash
# Test SSH from another terminal
ssh username@server-ip
# You'll be prompted for 6-digit code
```
## Configuration Details
### SSH Configuration Changes
File: `/etc/ssh/sshd_config`
```
ChallengeResponseAuthentication yes
UsePAM yes
AuthenticationMethods publickey,keyboard-interactive
```
### PAM Configuration
File: `/etc/pam.d/sshd`
```
auth required pam_google_authenticator.so nullok
```
### Cockpit Configuration
File: `/etc/cockpit/cockpit.conf`
```
[WebService]
LoginTitle = TSYS Server Management
LoginTo = 300
RequireHost = true
[Session]
Banner = /etc/cockpit/issue.cockpit
IdleTimeout = 15
```
### Webmin Configuration
File: `/etc/webmin/miniserv.conf`
```
twofactor_provider=totp
twofactor=1
```
## Security Considerations
### Gradual vs Strict Enforcement
#### Gradual Enforcement (Default)
- Uses `nullok` option in PAM
- Users without 2FA can still log in
- Allows phased rollout
- Good for initial deployment
#### Strict Enforcement
- Remove `nullok` from PAM configuration
- All users must have 2FA configured
- Immediate security enforcement
- Risk of lockout if misconfigured
### Backup and Recovery
#### Emergency Access
- **Backup codes:** Generated during setup
- **Root access:** Can disable 2FA if needed
- **Console access:** Physical/virtual console bypasses SSH
#### Configuration Backup
- Automatic backup to `/root/backup/2fa-TIMESTAMP/`
- Includes all modified configuration files
- Can be restored if needed
## Troubleshooting
### Common Issues
#### 1. User Cannot Generate QR Code
```bash
# Ensure qrencode is installed
sudo apt-get install qrencode
# Re-run user setup
sudo /tmp/setup-2fa-username.sh
```
#### 2. SSH Connection Fails
```bash
# Check SSH service status
sudo systemctl status sshd
# Test SSH configuration
sudo sshd -t
# Check logs
sudo journalctl -u sshd -f
```
#### 3. 2FA Code Not Accepted
- **Check time synchronization** on server and phone
- **Verify app setup** - rescan QR code if needed
- **Try backup codes** if available
#### 4. Locked Out of Server
```bash
# Access via console (physical/virtual)
# Disable 2FA temporarily
sudo cp /root/backup/2fa-*/pam.d.bak/sshd /etc/pam.d/sshd
sudo systemctl restart sshd
```
### Debug Commands
```bash
# Check 2FA status
./Project-Tests/security/2fa-validation.sh
# Check SSH configuration
sudo sshd -T | grep -E "(Challenge|PAM|Authentication)"
# Check PAM configuration
cat /etc/pam.d/sshd | grep google-authenticator
# Check user 2FA status
ls -la ~/.google_authenticator
```
## Management and Maintenance
### Adding New Users
1. Ensure user account exists
2. Run setup script for new user
3. Provide setup instructions
4. Test access
### Removing User 2FA
```bash
# Remove user's 2FA configuration
sudo rm /home/username/.google_authenticator
# User will need to re-setup 2FA
```
### Disabling 2FA System-Wide
```bash
# Restore original configurations
sudo cp /root/backup/2fa-*/sshd_config.bak /etc/ssh/sshd_config
sudo cp /root/backup/2fa-*/pam.d.bak/sshd /etc/pam.d/sshd
sudo systemctl restart sshd
```
### Updating 2FA Configuration
```bash
# Re-run setup script
sudo bash secharden-2fa.sh
# Validate changes
./Project-Tests/security/2fa-validation.sh
```
## Best Practices
### Deployment Strategy
1. **Test in non-production** environment first
2. **Enable gradual rollout** (nullok) initially
3. **Train users** on 2FA setup process
4. **Test emergency procedures** before strict enforcement
5. **Monitor logs** for authentication issues
### Security Recommendations
- **Enforce strict mode** after successful rollout
- **Regular backup code rotation**
- **Monitor failed authentication attempts**
- **Document emergency procedures**
- **Regular security audits**
### User Training
- **Provide clear instructions**
- **Demonstrate setup process**
- **Explain backup code importance**
- **Test login process with users**
- **Establish support procedures**
## Monitoring and Logging
### Authentication Logs
```bash
# SSH authentication logs
sudo journalctl -u sshd | grep -i "authentication"
# PAM authentication logs
sudo journalctl | grep -i "pam_google_authenticator"
# Failed login attempts
sudo journalctl | grep -i "failed"
```
### Security Monitoring
- Monitor for repeated failed 2FA attempts
- Alert on successful logins without 2FA (during gradual rollout)
- Track user 2FA setup completion
- Monitor for emergency access usage
## Integration with Existing Systems
### LDAP/Active Directory
- 2FA works with existing authentication systems
- Users still need local 2FA setup
- Consider centralized 2FA solutions for large deployments
### Monitoring Systems
- LibreNMS: Will continue to work with SNMP
- Wazuh: Will log 2FA authentication events
- Cockpit: Enhanced with 2FA protection
### Backup Systems
- Ensure backup procedures account for 2FA
- Test restore procedures with 2FA enabled
- Document emergency access procedures
## Support and Resources
### Files Created by Setup
- `/tmp/setup-2fa-*.sh` - User setup scripts
- `/home/*/2fa-setup-instructions.txt` - User instructions
- `/root/backup/2fa-*/` - Configuration backups
### Validation Tools
- `./Project-Tests/security/2fa-validation.sh` - Complete 2FA validation
- `./Project-Tests/run-tests.sh security` - Security test suite
### Emergency Contacts
- System Administrator: [Contact Info]
- Security Team: [Contact Info]
- 24/7 Support: [Contact Info]
## Compliance and Audit
### Security Benefits
- Significantly reduces risk of unauthorized access
- Meets multi-factor authentication requirements
- Provides audit trail of authentication events
- Complies with security frameworks (NIST, ISO 27001)
### Audit Trail
- All authentication attempts logged
- 2FA setup events recorded
- Configuration changes tracked
- Emergency access documented

GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate. Many developers of free software are heartened and encouraged by the resulting cooperation. However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. It requires the operator of a network server to provide the source code of the modified version running there to the users of that server. Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals. This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based on the Program.
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU Affero General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source. For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code. There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.
You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU AGPL, see <http://www.gnu.org/licenses/>.
