Information

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 are commonly used by attackers for network mapping and diagnosis.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Disable ICMP redirects on all external interfaces as shown in the example below.

[edit interfaces]
set ge-1/0/0 unit 0 family inet no-redirects
set ge-1/1/0 unit 0 family inet no-redirects
