Fix Recommendation

Configure the operating system to disable core dump backtraces.

Add or modify the following line in /etc/systemd/coredump.conf:

ProcessSizeMax=0

Check Contents

Note: If kernel dumps are disabled in accordance with OL09-00-002380, this requirement is not applicable.

Verify OL 9 disables core dump backtraces by issuing the following command:

$ grep -i process /etc/systemd/coredump.conf
ProcessSizeMax=0

If the "ProcessSizeMax" item is missing, commented out, or the value is anything other than "0" and the need for core dumps is not documented with the information system security officer (ISSO) as an operational requirement for all domains that have the "core" item assigned, this is a finding.
