OL 9 must prevent special devices on file systems that are used with removable media.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |

| Description | ||||
| The "nodev" mount option causes the system not to interpret character or block special devices. Executing character or blocking special devices from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access. | ||||

Check Text (C-271645r1091647_chk)
Verify that OL 9 file systems that are used for removable media are mounted with the "nodev" option with the following command:
$ more /etc/fstab
UUID=2bc871e4-e2a3-4f29-9ece-3be60c835222 /mnt/usbflash vfat noauto,owner,ro,nosuid,nodev,noexec 0 0
If a file system found in "/etc/fstab" refers to removable media and it does not have the "nodev" option set, this is a finding.
Fix Text (F-75602r1091646_fix)
Configure the "/etc/fstab" to use the "nodev" option on file systems that are associated with removable media.
