Description

The "/var/tmp" partition is used as temporary storage by many programs. Placing "/var/tmp" in its own partition enables the setting of more restrictive mount options, which can help protect programs that use it.

Check Text (C-75487r1091021_chk)

Verify that OL 9 uses a separate file system/partition for "/var/tmp" with the following command:

$ mount | grep /var/tmp
UUID=c274f65f-c5b5-4379-b017-bee96feb7a34 /var/log xfs noatime 1 2

If a separate entry for "/var/tmp" is not in use, this is a finding.

Fix Text (F-75394r1091022_fix)

Migrate the "/var/tmp" path onto a separate file system.
