Fix Recommendation

Configure the Cisco router to authenticate SNMP messages as shown in the example below.

R4(config)#snmp-server group V3GROUP v3 auth read V3READ write V3WRITE
R4(config)#snmp-server user V3USER V3GROUP v3 auth sha xxxxxxx
R4(config)#snmp-server view V3READ iso included
R4(config)#snmp-server view V3WRITE iso included
R4(config)#snmp-server host x.x.x.x version 3 auth V3USER

Check Contents

Review the Cisco router configuration to verify that it is compliant with this requirement as shown in the example below.

snmp-server group V3GROUP v3 auth read V3READ write V3WRITE
snmp-server view V3READ iso included
snmp-server view V3WRITE iso included
snmp-server host x.x.x.x version 3 auth V3USER

Authentication used by the SNMP users can be viewed via the show snmp user command as shown in the example below.

R4#show snmp user

User name: V3USER
Engine ID: 800000090300C2042B540000
storage-type: nonvolatile active
Authentication Protocol: SHA
Privacy Protocol: None
Group-name: V3GROUP

If the Cisco router is not configured to authenticate SNMP messages using a FIPS-validated HMAC, this is a finding.
