Fix Recommendation

Configure TOSS 5 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

Reload the system configuration files for the changes to take effect.

$ sudo sysctl --system

Check Contents

Verify TOSS 5 disables storing core dumps with the following commands:

$ sudo 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.
