Fix Recommendation

If the "/etc/snmp/snmpd.conf" file exists, modify any lines that contain a community string value of "public" or "private" to another string value.

Check Contents

Verify that a system using SNMP is not using default community strings.

Check to see if the "/etc/snmp/snmpd.conf" file exists with the following command:

# ls -al /etc/snmp/snmpd.conf
-rw------- 1 root root 52640 Mar 12 11:08 snmpd.conf

If the file does not exist, this is Not Applicable.

If the file does exist, check for the default community strings with the following commands:

# grep public /etc/snmp/snmpd.conf
# grep private /etc/snmp/snmpd.conf

If either of these commands returns any output, this is a finding.
