  • For site-to-site VPN implementations, the L2TP protocol must be blocked or denied at the security boundary with the private network so unencrypted L2TP packets cannot traverse into the private network of the enclave.

    &lt;VulnDiscussion&gt;Unlike GRE (a simple encapsulating header) L2TP is a full-fledged communications protocol with control channel, data channels...

  • The VPN Client must implement multifactor authentication for network access to nonprivileged accounts such that one of the factors is provided by a device separate from the system gaining access.

    &lt;VulnDiscussion&gt;Using an authentication device, such as a common access card (CAC) or token that is separate from the information system, ens...

  • The VPN Gateway, when utilizing PKI-based authentication, must validate certificates by constructing a certification path (which includes status information) to an accepted trust anchor.

    &lt;VulnDiscussion&gt;Without path validation, an informed trust decision by the relying party cannot be made when presented with any certificate n...
