Rules and Groups employed by this XCCDF Profile

  • SRG-NET-000362-RTR-000122

    <GroupDescription></GroupDescription>
    Group
  • The Juniper multicast Designated Router (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...

  • SRG-NET-000362-RTR-000123

    <GroupDescription></GroupDescription>
    Group
  • The Juniper multicast Designated Router (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...

    <GroupDescription></GroupDescription>
    Group
  • The Juniper Multicast Source Discovery Protocol (MSDP) router must be configured to only accept MSDP packets from known MSDP peers.

    &lt;VulnDiscussion&gt;MSDP peering with customer network routers presents additional risks to the DISN Core, whether from a rogue or misconfigured ...

    Group
  • The Juniper Multicast Source Discovery Protocol (MSDP) router must be configured to authenticate all received MSDP packets.

    &lt;VulnDiscussion&gt;MSDP peering with customer network routers presents additional risks to the core, whether from a rogue or misconfigured MSDP-...

    <GroupDescription></GroupDescription>
    Group
  • The Juniper Multicast Source Discovery Protocol (MSDP) router must be configured to filter received source-active multicast advertisements for any undesirable multicast groups and sources.

    &lt;VulnDiscussion&gt;The interoperability of BGP extensions for interdomain multicast routing and MSDP enables seamless connectivity of multicast ...

  • SRG-NET-000018-RTR-000008

    <GroupDescription></GroupDescription>
    Group
  • The Juniper Multicast Source Discovery Protocol (MSDP) router must be configured to filter source-active multicast advertisements to external MSDP peers to avoid global visibility of local-only multicast sources and groups.

    &lt;VulnDiscussion&gt;To avoid global visibility of local information, there are a number of source-group (S, G) states in a PIM-SM domain that mus...

  • SRG-NET-000018-RTR-000009

    <GroupDescription></GroupDescription>
    Group
  • The Juniper Multicast Source Discovery Protocol (MSDP) router must be configured to limit the amount of source-active messages it accepts on per-peer basis.

    &lt;VulnDiscussion&gt;To reduce any risk of a denial-of-service (DoS) attack from a rogue or misconfigured MSDP router, the router must be configur...
    Rule Low Severity
  • SRG-NET-000512-RTR-000011

    <GroupDescription></GroupDescription>
    Group
  • The Juniper Multicast Source Discovery Protocol (MSDP) router must be configured to use its loopback address as the source address when originating MSDP traffic.

    &lt;VulnDiscussion&gt;Using a loopback address as the source address offers a multitude of uses for security, access, management, and scalability o...

  • SRG-NET-000512-RTR-000014

    <GroupDescription></GroupDescription>
    Group
  • The Juniper perimeter router must be configured to suppress Router Advertisements on all external IPv6-enabled interfaces.

    &lt;VulnDiscussion&gt;Many of the known attacks in stateless autoconfiguration are defined in RFC 3756 were present in IPv4 ARP attacks. To mitigat...

  • SRG-NET-000512-RTR-000013

    <GroupDescription></GroupDescription>
    Group
  • The Juniper router must not be configured to use IPv6 Site Local Unicast addresses.

    &lt;VulnDiscussion&gt;As currently defined, site local addresses are ambiguous and can be present in multiple sites. The address itself does not co...

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.
