Fix Recommendation

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

$ sudo 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 if "kdump" service is active with the following command:

$ systemctl is-active kdump.service
inactive

If the "kdump" service is active, ask the SA if the use of the service is required and documented with the ISSO.

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