### Security Mechanisms
|
|
|
|
|
|
#### What physical security mechanisms will be used?
|
|
|
|
- ::Servers will be kept in a locked room with door code known only
|
|
to administrators.
|
|
- ::Servers will be kept in a locked equipment rack.
|
|
- ::Server case itself has a security cable that prevents the case
|
|
from being opened (so the hard-disk with sensitive data cannot
|
|
be removed).
|
|
- ::Backup tapes are stored in a locked cabinet in a locked room.
|
|
|
|
#### What network security mechanisms will be used?
|
|
|
|
- ::A firewall device limits access to specific network ports (e.g.,
|
|
port 80 for web server access).
|
|
- ::Firewall software limits access to specific network ports (e.g.,
|
|
port 80 for web server access).
|
|
- ::Only the front-end machines are accessible over the Internet.
|
|
Other machines in the server cluster communicate over a private
|
|
LAN only.
|
|
- ::Users can only connect to the server from specific ranges of
|
|
IP-address (e.g., university-owned computers in networks
|
|
on campus).
|
|
- ::Certain users (e.g., administrators) can only connect from
|
|
specific ranges of IP-addresses.
|
|
- ::All network communication takes place over a virtual private
|
|
network (VPN) that is encrypted and not accessible to outsiders.
|
|
- ::All network communication takes place over a LAN that does not
|
|
have any connections to the Internet.
|
|
|
|
#### What operating system security will be used?
|
|
|
|
- ::Operating system user accounts will never be created on the
|
|
servers, other than those needed by the application itself.
|
|
- ::Different components in the application execute as different
|
|
operating system users, have only the least possible privileges,
|
|
and may only access the particular files needed by
|
|
that component.
|
|
- ::Operating system permissions on files and directories are set to
|
|
prevent undesired access or modification.
|
|
- ::Intrusion detection software will be used on the server to
|
|
detect any modifications made by hackers.
|
|
- ::Administrators will monitor security mailing lists for
|
|
announcements of security holes in any components that we use
|
|
and security patches and upgrades will be applied quickly.
|
|
- ::Data on disks and backup tapes is stored using an encrypted file
|
|
system so that the data is protected if the media itself is
|
|
stolen or somehow accessed.
|
|
|
|
#### What application security mechanisms will be used?
|
|
|
|
- ::Values input into every field are validated before use
|
|
- ::Usernames and passwords are required for access
|
|
- ::Passwords are stored encrypted
|
|
- ::Verification of user email address
|
|
- ::The quality of passwords is checked
|
|
- ::Users must have certificate files on their client machine before
|
|
they can connect to the server
|
|
- ::Users must have physical security tokens (e.g., hasp, dongle,
|
|
smart-card, or fingerprint reader)
|
|
- ::Users are given roles that define their permissions. Those roles
|
|
are:
|
|
- ::Guest: Visitor to the site is not logged in, no permissions
|
|
to change anything
|
|
- ::Guest: Visitor to the site is not logged in, can post
|
|
messages anonymously
|
|
- ::RegisteredUser: User is logged in, has permissions for X, Y,
|
|
and Z
|
|
- ::Administrator: Permission to change anything, even on behalf
|
|
of other regular users
|
|
- ::Each action (information display or change) requires that the
|
|
user has a role with proper permissions
|
|
- ::Compromised or abused accounts can be quickly disabled
|
|
by administrators. >
|
|
- ::Administrators can review user > permissions
|
|
- ::Administrators can audit all a > ccesses and changes
|
|
- ::All communications with the us > er are encrypted (e.g., SSL)
|
|
- ::Some communications with the user (e.g., the username
|
|
and password) are encrypted (e.g., SSL)
|
|
- ::Sessions are tied to a particular client IP-address so that
|
|
stolen cookies cannot be used.
|
|
- ::Session cookies are long random strings that cannot be guessed.
|
|
- ::Sessions time out so that unattended terminals cannot be abused.
|
|
- ::Actions that seem to destroy data actually move it to a place
|
|
where it can still be reviewed by administrators.
|
|
- ::Sensitive data, such as credit card numbers, are processed but
|
|
not retained in any database or file
|
|
- ::The data access layer will be responsible for preventing SQL
|
|
injection attacks (i.e., hackers attempting to enter SQL
|
|
statements through application UI fields).
|
|
- ::The data access layer will allow read-only connections, which
|
|
will be used for most requests, as well as write connections for
|
|
requests that update the database.
|
|
- ::The HTML generation layer will be responsible for preventing
|
|
cross-site-scripting (XSS) attacks.
|
|
- ::The application will prevent CSRF attacks. It will do this by
|
|
performing updates to the database only after a POST, and
|
|
checking that the referring page was served by the system for
|
|
every POST. Browsers that do not report HTTP-Referrer will not
|
|
be supported.
