Title

The SNMP service must use only SNMPv3 or its successors. (Cat II impact)

Discussion

SNMP Versions 1 and 2 are not considered secure. Without the strong authentication and privacy provided by the SNMP Version 3 User-based Security Model (USM), an attacker or other unauthorized users may gain access to detailed system management information and use the information to launch attacks against the system.

Check Content

Verify the SNMP daemon is not configured to use community strings. # grep community /etc/snmp/conf | grep -v '^#' If any configuration is found, this is a finding.

Fix Text

Edit /etc/snmp/conf to remove references to community strings. Restart the SNMP service.
