| 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-271437r1091023_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.
