Fix Recommendation

Configure OL 8 to disable storing core dumps.

Add or edit the following line in a system configuration file, in the "/etc/sysctl.d/" directory:

kernel.core_pattern = |/bin/false

The system configuration files must be reloaded for the changes to take effect. To reload the contents of the files, run the following command:

$ sudo sysctl --system

Check Contents

Verify OL 8 disables storing core dumps with the following commands:

$ sysctl kernel.core_pattern
kernel.core_pattern = |/bin/false

If the returned line does not have a value of "|/bin/false", or a line is not returned and the need for core dumps is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
