  • The VPN Gateway must generate unique session identifiers using FIPS-validated Random Number Generator (RNG) based on the Deterministic Random Bit Generators (DRBG) algorithm.

    &lt;VulnDiscussion&gt;Both IPsec and TLS gateways use the RNG to strengthen the security of the protocols. Using a weak RNG will weaken the protoco...

  • The VPN Gateway must fail to a secure state if system initialization fails, shutdown fails, or aborts fail.

    &lt;VulnDiscussion&gt;Failure to a known safe state helps prevent systems from failing to a state that may cause loss of data or unauthorized acces...

  • The VPN Gateway administrator accounts or security policy must be configured to allow the system administrator to immediately disconnect or disable remote access to devices and/or users when needed.

    &lt;VulnDiscussion&gt;Without the ability to immediately disconnect or disable remote access, an attack or other compromise taking progress would n...

  • The IPsec VPN Gateway must use AES encryption for the Internet Key Exchange (IKE) proposal to protect confidentiality of remote access sessions.

    &lt;VulnDiscussion&gt;Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote...

  • The VPN Gateway must off-load audit records onto a different system or media than the system being audited.

    &lt;VulnDiscussion&gt;Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common...

  • The VPN Gateway must generate a log record or an SNMP trap that can be forwarded as an alert to, at a minimum, the SCA and ISSO, of all log failure events where the detection and/or prevention function is unable to write events to either local storage or the centralized server.

    &lt;VulnDiscussion&gt;It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required....

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
