CISC-RT-000070 - The Cisco router must be configured to have all non-essential capabilities disabled.

Information

A compromised router introduces risk to the entire network infrastructure, as well as data resources that are accessible via the network. The perimeter defense has no oversight or control of attacks by malicious users within the network. Preventing network breaches from within is dependent on implementing a comprehensive defense-in-depth strategy, including securing each device connected to the network. This is accomplished by following and implementing all security guidance applicable for each node type. A fundamental step in securing each router is to enable only the capabilities required for operation.

Solution

Disable the following services if enabled as shown in the example below.

RP/0/0/CPU0:R3(config)#no service ipv4 tcp-small-servers
RP/0/0/CPU0:R3(config)#no service ipv4 udp-small-servers
RP/0/0/CPU0:R3(config)#no http client vrf xxxxx
RP/0/0/CPU0:R3(config)#no telnet ipv4 server
