Information

The Cisco switch must be configured to prohibit the use of all unnecessary and nonsecure functions and services.

GROUP ID: V-220486
RULE ID: SV-220486r1043177

Network devices are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations. Additionally, it is sometimes convenient to provide multiple services from a single component (e.g., email and web services); however, doing so increases risk over limiting the services provided by any one component.

To support the requirements and principles of least functionality, the network device must support the organizational requirements providing only essential capabilities and limiting the use of ports, protocols, and/or services to only those required, authorized, and approved. Some network devices have capabilities enabled by default; if these capabilities are not necessary, they must be disabled. If a particular capability is used, then it must be documented and approved.

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

Solution

Disable features that should not be enabled unless required for operations.

SW2(config)# no feature telnet
SW2(config)# no feature dhcp
SW2(config)# no feature wccp
SW2(config)# no feature nxapi
SW2(config)# no feature imp

Note: Telnet must always be disabled.
