Information

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, it must be documented and approved.

Solution

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

SW2(config)#no boot network
SW2(config)#no ip boot server
SW2(config)#no ip bootp server
SW2(config)#no ip dns server
SW2(config)#no ip identd
SW2(config)#no ip finger
SW2(config)#no ip http server
SW2(config)#no ip rcmd rcp-enable
SW2(config)#no ip rcmd rsh-enable
SW2(config)#no service config
SW2(config)#no service finger
SW2(config)#no service tcp-small-servers
SW2(config)#no service udp-small-servers
SW2(config)#no service pad
SW2(config)#end
