Title
All device files must be monitored by the system Linux Security Module. (Cat III impact)
Discussion
If a device file carries the SELinux type "unlabeled_t", then SELinux cannot properly restrict access to the device file.
Check Content
To check for unlabeled device files, run the following command: # ls -RZ /dev | grep unlabeled_t It should produce no output in a well-configured system. If there is output, this is a finding.
Fix Text
Device files, which are used for communication with important system resources, should be labeled with proper SELinux types. If any device files carry the SELinux type "unlabeled_t", investigate the cause and correct the file's context.
