Check Contents

Review the switch configuration to verify that the switch 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

Note: ip http server can be enabled provided that the "ip http active-session-modules none" command is configured for scenarios such as ISE sending URL redirects to the switch.

If any unnecessary services are enabled, this is a finding.
