Cisco IOS XE Switch RTR Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The Cisco multicast Rendezvous Point (RP) switch must be configured to filter Protocol Independent Multicast (PIM) Join messages received from the Designated Cisco switch (DR) for any undesirable multicast groups.

    <VulnDiscussion>Real-time multicast traffic can entail multiple large flows of data. An attacker can flood a network segment with multicast p...

  • The Cisco multicast Rendezvous Point (RP) must be configured to rate limit the number of Protocol Independent Multicast (PIM) Register messages.

  • 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 only multicast groups that have been approved by the organization.

  • 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 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.
