Fix Recommendation

Configure Amazon Linux 2023 so that "/dev/shm" is mounted with the "nodev" option.

Modify "/etc/fstab" to use the "nodev" option on the "/dev/shm" file system.

Check Contents

Verify Amazon Linux 2023 is configured so that "/dev/shm" is mounted with the "nodev" option with the following command:

$ mount | grep /dev/shm
tmpfs on /dev/shm type tmpfs (rw,nodev,nosuid,noexec,seclabel)

If the /dev/shm file system is mounted without the "nodev" option, this is a finding.
