AlmaLinux OS 9 must prevent code from being executed on file systems that are used with removable media.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-269282 | ALMA-09-022790 | SV-269282r1050164_rule | CCI-000366 | medium |
| Description | ||||
| The "noexec" mount option causes the system to not execute binary files. This option must be used for mounting any file system not containing approved binary files, as they may be incompatible. Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access. | ||||

Check Text (C-269282r1050164_chk)
Verify file systems that are used for removable media are mounted with the "noexec" option with the following command:
$ cat /etc/fstab
UUID=0cb43738-b102-48f8-9174-061d8ee537b8 /mnt/usbdrive 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 "noexec" option set, this is a finding.
Fix Text (F-73214r1048223_fix)
Configure the "/etc/fstab" to use the "noexec" option on file systems that are associated with removable media.
