Check Text ( C-46213r2_chk )
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 the default password is not set, run the following command: # grep -v "^#" /etc/snmp/snmpd.conf| grep public There should be no output. If there is output, this is a finding.

Fix Text (F-43602r1_fix)
Edit "/etc/snmp/snmpd.conf", remove default community string "public". Upon doing that, restart the SNMP service: # service snmpd restart
