Description
Whether active or not, default SNMP passwords, users, and passphrases must be changed to maintain security. If the service is running with the default authenticators, then anyone can gather data about the system and the network and use the information to potentially compromise the integrity of the system or network(s).

Fix Text (F-1147r2_fix)
Change the default passwords. To change them, locate the snmpd.conf file and edit it. Locate the line system-group-read-community which has a default password of public and make the password something more random (less guessable). Make the same changes for the lines that read 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 is not a password, but the name of a host.
