Discussion

A compromised switch 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 switch is to enable only the capabilities required for operation.

Fix

Disable features that should not be enabled unless required for operations. SW2(config)# no feature telnet SW2(config)# no feature wccp SW2(config)# no feature nxapi SW2(config)# no feature imp Note: Telnet must always be disabled.
