Title

The rstatd daemon must be disabled on AIX. (Cat II impact)

Discussion

The rstatd service is used to provide kernel statistics and other monitorable parameters pertinent to the system such as: CPU usage, system uptime, network usage etc. An attacker may use this information in a DoS attack. This service should be disabled.

Check Content

From the command prompt, execute the following command: # grep "^rstatd[[:blank:]]" /etc/inetd.conf If there is any output from the command, this is a finding.

Fix Text

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