AIX7-00-003076 - The rusersd daemon must be disabled on AIX.

Information

The rusersd service runs as root and provides a list of current users active on a system. An attacker may use this service to learn valid account names on the system. This is not an essential service and should be disabled.

Solution

In '/etc/inetd.conf', comment out the 'rusersd' entry by running command:
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'rusersd' -p 'udp'

Restart inetd:
# refresh -s inetd
