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
