Description |
---|
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. |

Review the router configuration to verify that the router does not have any unnecessary or non-secure services enabled. For example, the following commands should not be in the configuration: boot network ip boot server ip bootp server ip dns server ip identd ip finger ip http server ip rcmd rcp-enable ip rcmd rsh-enable service config service finger service tcp-small-servers service udp-small-servers service pad If any unnecessary services are enabled, this is a finding. |
