  • The Cisco multicast Designated switch (DR) must be configured to filter the Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) Report messages to allow hosts to join a multicast group only from sources that have been approved by the organization.

    &lt;VulnDiscussion&gt;Real-time multicast traffic can entail multiple large flows of data. Large unicast flows tend to be fairly isolated (i.e., so...

  • The Cisco multicast Designated switch (DR) must be configured to limit the number of mroute states resulting from Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) Host Membership Reports.

    &lt;VulnDiscussion&gt;The current multicast paradigm can let any host join any multicast group at any time by sending an IGMP or MLD membership rep...

  • The Cisco perimeter switch must be configured drop IPv6 packets with a Routing Header type 0, 1, or 3-255.

    &lt;VulnDiscussion&gt;The routing header can be used maliciously to send a packet through a path where less robust security is in place, rather tha...

  • The Cisco multicast Designated switch (DR) must be configured to set the shortest-path tree (SPT) threshold to infinity to minimalize source-group (S, G) state within the multicast topology where Any Source Multicast (ASM) is deployed.

    &lt;VulnDiscussion&gt;ASM can have many sources for the same groups (many-to-many). For many receivers, the path via the RP may not be ideal compar...

  • The Cisco perimeter switch 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.
