Description
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 Text (C-220500r961506_chk)

Review the Cisco switch configuration to verify that it is compliant with this requirement as shown in the example below: snmp-server user NETOPS auth sha 5Er23@#as178 priv aes-128 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx snmp-server host 10.1.48.10 traps version 3 priv NETOPS Authentication used by the SNMP users can be viewed via the show snmp user command as shown in the example below: SW1# show snmp user ______________________________________________________________ SNMP USERS ______________________________________________________________ User Auth Priv(enforce) Groups acl_filter ____ ____ ___________ ______ __________ NETOPS sha aes-128 network-operator If the Cisco switch is not configured to authenticate SNMP messages using a FIPS-validated HMAC, this is a finding.

Fix Text (F-22204r940002_fix)

Configure the Cisco switch to authenticate SNMP messages as shown in the example below: SW1(config)# snmp-server user NETOPS auth sha xxxxxxxxxxxxx priv aes-128 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx SW1(config)# snmp-server host 10.1.48.10 traps version 3 priv NETOPS
