Description
Whether active or not, default SNMP passwords, users, and passphrases must be changed to maintain security.

Fix Text (F-31974r1_fix)
Change the default passwords. To change them, edit the /etc/SnmpAgent.d/snmpd.conf file. Locate the line system-group-read-community which has a default password of public and make the password something more random (less guessable). Do the same for the lines reading system-group-write-community, read-community, write-community, trap, and trap-community. Read the information in the file carefully. The trap is defining who to send traps to, for instance, by default. It will not be a password, but the name of a host.
