OL 9 must use a separate file system for /tmp.

Rule version OL09-00-000004 · STIG v1 · 2026-08-21

Discussion

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

Check

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

$ mount | grep /tmp tmpfs /tmp tmpfs noatime,mode=1777 0 0

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

Fix

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