1.10 CISC-RT-000190

Information

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

GROUP ID: V-221002
RULE ID: SV-221002r856407

The ICMP supports IP traffic by relaying information about paths, routes, and network conditions. Switches 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:

SW1(config)#int g0/1
SW1(config-if)#no ip redirects
