Rules, Groups, and Values defined within the XCCDF Benchmark

  • The Juniper router providing connectivity to the NOC must be configured to forward all in-band management traffic via an IPsec tunnel.

    <VulnDiscussion>When the production network is managed in-band, the management network could be housed at a NOC that is located remotely at s...

  • The Juniper BGP router must be configured to enable the Generalized TTL Security Mechanism (GTSM).

    &lt;VulnDiscussion&gt;GTSM is designed to protect a router's IP-based control plane from DoS attacks. Many attacks focused on CPU load and line-car...

  • The Juniper BGP router must be configured to use a unique key for each autonomous system (AS) that it peers with.

    &lt;VulnDiscussion&gt;If the same keys are used between eBGP neighbors, the chance of a hacker compromising any of the BGP sessions increases. It i...

  • The Juniper BGP router must be configured to reject inbound route advertisements for any Bogon prefixes.

  • The Juniper BGP router must be configured to reject inbound route advertisements from a customer edge (CE) Juniper router for prefixes that are not allocated to that customer.
