    <GroupDescription></GroupDescription>
    Group
  • 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...

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

  • SRG-NET-000320

    <GroupDescription></GroupDescription>
    Group
  • The VPN Gateway must transmit organization-defined access authorization information using FIPS 140-2-validated cryptography to a compliant authentication server, which enforces access control decisions.

    &lt;VulnDiscussion&gt;Protecting authentication communications between the client, the VPN Gateway, and the authentication server keeps this critic...

    <GroupDescription></GroupDescription>
    Group
  • The VPN Gateway must notify the user, upon successful logon (access), of the organization-defined information to be included in addition to the date and time of the last logon (access).

    Group
  • The VPN Gateway must provide centralized management and configuration of the content to be captured in log records generated by all network components.

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.
