Check Text (C-261270r996860_chk)
Verify that SLEM 5 kernel core dumps are disabled unless needed with the following command:
> systemctl status kdump.service
kdump.service - Load kdump kernel and initrd
Loaded: loaded (/usr/lib/systemd/system/kdump.service; disabled; vendor preset: disabled)
Active: inactive (dead)
If "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.
