NAMEmount_selinux - Security Enhanced Linux Policy for the mount processes
SELinux Linux secures mount (Policy for mount) processes via flexible mandatory access control.
BOOLEANSSELinux policy is customizable based on least access required. mount policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mount with the tightest access possible.
If you want to allow the mount command to mount any directory or file, you must turn on the allow_mount_anyfile boolean.
setsebool -P allow_mount_anyfile 1
If you want to allow xguest users to mount removable medi, you must turn on the xguest_mount_media boolean.
setsebool -P xguest_mount_media 1
FILE CONTEXTSSELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux mount policy is very flexible allowing users to setup their mount processes in as secure a method as possible.
The following file types are defined for mount:
- Set files with the mount_exec_t type, if you want to transition an executable to the mount_t domain.
/sbin/mount.*, /sbin/umount.*, /bin/umount.*, /bin/mount.*
- Set files with the mount_loopback_t type, if you want to treat the files as mount loopback data.
- Set files with the mount_tmp_t type, if you want to store mount temporary files in the /tmp directories.
- Set files with the mount_var_run_t type, if you want to store the mount files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
PROCESS TYPESSELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux mount policy is very flexible allowing users to setup their mount processes in as secure a method as possible.
The following process types are defined for mount:
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
COMMANDSsemanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
