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.

Check Text (C-73332r1048279_chk)

Verify that a separate file system/partition has been created for "/tmp" with the following command:

$ mount | grep ' /tmp '

tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noexec,relatime,seclabel,size=2097152k,inode64)

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

Fix Text (F-73233r1048280_fix)

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