Discussion

Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk. A local connection is any connection with a device communicating without the use of a network. A network connection is any connection with a device that communicates through a network (e.g., local area or wide area network, internet). A remote connection is any connection with a device communicating through an external network (e.g., the internet). Because of the challenges of applying this requirement on a large scale, organizations are encouraged to only apply the requirement to those limited number (and type) of devices that truly need to support this capability.

Check Content

To show the current FIPS mode setting, use the show command from the CLI configuration mode.

apic1(config) show fips status

If FIPS mode is not set to "Enable", this is a finding.

Fix Text

From the CLI configuration mode, enable FIPS mode on all nodes and then reboot all nodes to activate FIPS compliance. 

apic1(config)# fips mode enable
