  • The Juniper perimeter router must be configured to protect an enclave connected to an alternate gateway by using an inbound filter that only permits packets with destination addresses within the sites address space.

    &lt;VulnDiscussion&gt;Enclaves with alternate gateway connections must take additional steps to ensure there is no compromise on the enclave networ...

  • The Juniper perimeter router must be configured to not be a Border Gateway Protocol (BGP) peer to an alternate gateway service provider.

    &lt;VulnDiscussion&gt;ISPs use BGP to share route information with other autonomous systems (i.e. other ISPs and corporate networks). If the perime...

  • The Juniper perimeter router must be configured to not redistribute static routes to an alternate gateway service provider into BGP or an IGP peering with the NIPRNet or to other autonomous systems.

    &lt;VulnDiscussion&gt;If the static routes to the alternate gateway are being redistributed into an Exterior Gateway Protocol or Interior Gateway P...

  • The Juniper perimeter router must be configured to restrict it from accepting outbound IP packets that contain an illegitimate address in the source address field via egress filter or by enabling Unicast Reverse Path Forwarding (uRPF).

    &lt;VulnDiscussion&gt;A compromised host in an enclave can be used by a malicious platform to launch cyberattacks on third parties. This is a commo...

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.
