ProcessSizeMax=0

Check Contents

Verify TOSS 5 disables core dump backtraces using 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.
