Juniper Router RTR Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The Juniper PE router providing Virtual Private LAN Services (VPLS) must be configured to have traffic storm control thresholds on CE-facing interfaces.

    <VulnDiscussion>A traffic storm occurs when packets flood a VPLS bridge, creating excessive traffic and degrading network performance. Traffi...

  • The Juniper PE router must be configured to have each VRF with the appropriate Route Distinguisher (RD).

    &lt;VulnDiscussion&gt;An RD provides uniqueness to the customer address spaces within the MPLS L3VPN infrastructure. The concept of the VPN-IPv4 an...

  • The Juniper PE router providing MPLS Layer 2 Virtual Private Network (L2VPN) services must be configured to authenticate targeted Label Distribution Protocol (LDP) sessions used to exchange virtual circuit (VC) information using a FIPS-approved message authentication code algorithm.

    &lt;VulnDiscussion&gt;LDP provides the signaling required for setting up and tearing down pseudowires (virtual circuits used to transport Layer 2 f...

  • The Juniper PE router providing MPLS Virtual Private Wire Service (VPWS) must be configured to have the appropriate virtual circuit identification (VC ID) for each attachment circuit.

    &lt;VulnDiscussion&gt;VPWS is an L2VPN technology that provides a virtual circuit between two PE routers to forward Layer 2 frames between two cust...

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.
