Fix Recommendation

Configure the Cisco router to encrypt SNMP messages using a FIPS 140-2 approved algorithm as shown in the example below.

RP/0/0/CPU0:R3(config)#snmp-server group V3GROUP v3 auth read V3READ write V3WRITE
RP/0/0/CPU0:R3(config)#snmp-server user V3USER V3GROUP v3 auth sha xxxxxx priv aes 256 xxxxxx
RP/0/0/CPU0:R3(config)#snmp-server view V3READ iso included
RP/0/0/CPU0:R3(config)#snmp-server view V3WRITE iso included
RP/0/0/CPU0:R3(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 host x.x.x.x traps version 3 auth V3USER
snmp-server user V3USER V3GROUP v3 auth sha encrypted 110B1607150B
snmp-server view V3READ iso included
snmp-server view V3WRITE iso included
snmp-server group V3GROUP v3 auth read V3READ write V3WRITE

If the Cisco router is not configured to encrypt SNMP messages using a FIPS 140-2 approved algorithm, this is a finding.
