Fix Recommendation

Configure OL 8 so that "/dev/shm" is mounted with the "nodev" option by adding/modifying "/etc/fstab" with the following line:

tmpfs /dev/shm tmpfs defaults,nodev,nosuid,noexec 0 0

Check Contents

Verify "/dev/shm" is mounted with the "nodev" option:

$ sudo mount | grep /dev/shm

tmpfs on /dev/shm type tmpfs (rw,nodev,nosuid,noexec,seclabel)

Verify that the "nodev" option is configured for "/dev/shm":

$ sudo cat /etc/fstab | grep /dev/shm

tmpfs /dev/shm tmpfs defaults,nodev,nosuid,noexec 0 0

If results are returned and the "nodev" option is missing, or if "/dev/shm" is mounted without the "nodev" option, this is a finding.
