Fix Recommendation

Configure the operating system to disable core dump backtraces.

Add or modify the following line in the [Coredump} section of /etc/systemd/coredump.conf:

ProcessSizeMax=0

Check Contents

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

$ systemd-analyze cat-config systemd/coredump.conf | grep ProcessSizeMax

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.
