Fix Recommendation

If kernel core dumps are not required, disable the "kdump" service with the following command:

# systemctl disable kdump.service

If kernel core dumps are required, document the need with the ISSO.

Check Contents

Verify that kernel core dumps are disabled unless needed.

Check the status of the "kdump" service with the following command:

# systemctl status kdump.service
kdump.service - Crash recovery kernel arming
Loaded: loaded (/usr/lib/systemd/system/kdump.service; enabled)
Active: active (exited) since Wed 2015-08-26 13:08:09 EDT; 43min ago
Main PID: 1130 (code=exited, status=0/SUCCESS)
kernel arming.

If the "kdump" service is active, ask the System Administrator if the use of the service is required and documented with the Information System Security Officer (ISSO).

If the service is active and is not documented, this is a finding.
