Description
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.
ℹ️ Check
Verify that a separate file system/partition has been created for "/tmp" with the following command: $ mount | grep /tmp /dev/mapper/rhel-tmp on /tmp type xfs (rw,nodev,nosuid,noexec,seclabel) If a separate entry for "/tmp" is not in use, this is a finding.
✔️ Fix
Migrate the "/tmp" path onto a separate file system.
