Fix Recommendation

Configure RHEL 10 to disable core dumps for all users.

Create or edit the setting in a drop-in configuration file:

$ sudo vi /etc/security/limits.d/core_dumps.conf

Add the following line:

* hard core 0

Remove any entries for users or groups with a value set to anything other than "0".

Check Contents

Note: If kernel dumps are disabled in accordance with RHEL-10-701090, this requirement is not applicable.

Verify RHEL 10 disables core dumps for all users by issuing the following command:

$ sudo grep -r core /etc/security/ | grep -v '#'
/etc/security/limits.d/core_dumps.conf:* hard core 0

This can be set as a global domain (with the * wildcard) but may be set differently for multiple domains.

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