Juniper Router RTR Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The Juniper router must be configured to have Internet Control Message Protocol (ICMP) unreachable messages disabled on all external interfaces.

    The ICMP supports IP traffic by relaying information about paths, routes, and network conditions. Routers automatically send ICMP messages under a wide variety of conditions. Host unreachable ICMP ...

  • The Juniper router must be configured to have Internet Control Message Protocol (ICMP) redirect messages disabled on all external interfaces.

    The ICMP supports IP traffic by relaying information about paths, routes, and network conditions. Routers automatically send ICMP messages under a wide variety of conditions. Redirect ICMP messages...

  • The Juniper router must be configured to log all packets that have been dropped.

    Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being done or attempted to be done, and by whom, to compile an accurate ...

  • SRG-NET-000077-RTR-000001

    Group
  • The Juniper router must be configured to produce audit records containing information to establish the source of the events.

    Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessmen...

    Group
  • The Juniper perimeter router must be configured to deny network traffic by default and allow network traffic by exception.

    A deny-all, permit-by-exception network communications traffic policy ensures that only connections that are essential and approved are allowed. This requirement applies to both inbound and outbou...

  • SRG-NET-000019-RTR-000002

    Group
  • The Juniper perimeter router must be configured to enforce approved authorizations for controlling the flow of information between interconnected networks in accordance with applicable policy.

    Information flow control regulates authorized information to travel within a network and between interconnected networks. Controlling the flow of network traffic is critical so it does not introduc...

  • The Juniper perimeter router must be configured to block inbound packets with source Bogon IP address prefixes.

    Packets with Bogon IP source addresses should never be allowed to traverse the IP core. Bogon IP networks are RFC1918 addresses or address blocks that have never been assigned by the IANA or have b...

  • The Juniper perimeter router must be configured to not be a Border Gateway Protocol (BGP) peer to an approved gateway service provider.

    Internet service providers (ISPs) use BGP to share route information with other autonomous systems (i.e., other ISPs and corporate networks). If the perimeter router was configured to BGP peer with...
