Ensure rstatd daemon is not in use
Description
This entry starts the rstatd daemon. This service is used to provide kernel statistics and other monitorable parameters such as CPU usage, system uptime, network usage etc. This service should be disabled if not explicitly required by performance monitoring software to collect statistics. 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. Audit: `lssrc -s inetd -l` must not list the service (count 0).
How it is checked
Audit method: Shell command
command -v lssrc >/dev/null 2>&1 || exit 1; n=$(lssrc -s inetd -l 2>/dev/null | grep -c 'rstatd'); echo "$n"- Expected output
0
How it is fixed
Fix method: Guidance or infrastructure patch
In /etc/inetd.conf, comment out the rstatd entry and refresh the inetd process: chsubserver -r inetd -C /etc/inetd.conf -d -v 'rstatd' -p udp lssrc -s inetd && refresh -s inetd
