| Verify the "snmp" package is installed: # rpm -qa | grep -i snmp net-snmp-5.7.1-31.2.x86_64.rpm If the package is not installed, this is Not Applicable. To ensure only SNMPv3 or newer is used, run the following command: # grep 'v1\|v2c\|com2sec' /etc/snmp/snmpd.conf | grep -v '^#' There should be no output. If there is output, this is a finding. |

| Edit "/etc/snmp/snmpd.conf", removing any references to "v1", "v2c", or "com2sec". Upon doing that, restart the SNMP service: # service snmpd restart |
