Assessment Title

Rule Text

The snmpd.conf file must be group-owned by root, sys, bin or other.

Description

Discussion Text

The snmpd.conf file contains authenticators and must be protected from unauthorized access and modification. If the file is not group-owned by root or a system group, it may be subject to access and modification from unauthorized users.

Remediation

Change the group ownership of the SNMP configuration file.
# chgrp root /etc/SnmpAgent.d/snmpd.conf
