gfs_selinux: Security Enhanced Linux Policy for the gfs processes
NAMEgfs_selinux - Security Enhanced Linux Policy for the gfs processes
Security-Enhanced Linux secures the gfs processes via flexible mandatory access control.
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 gfs policy is very flexible allowing users to setup their gfs processes in as secure a method as possible.
The following file types are defined for gfs:
- Set files with the gfs_controld_exec_t type, if you want to transition an executable to the gfs_controld_t domain.
- Set files with the gfs_controld_tmpfs_t type, if you want to store gfs controld files on a tmpfs file system.
- Set files with the gfs_controld_var_log_t type, if you want to treat the data as gfs controld var log data, usually stored under the /var/log directory.
- Set files with the gfs_controld_var_run_t type, if you want to store the gfs controld files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanantly 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 gfs policy is very flexible allowing users to setup their gfs processes in as secure a method as possible.
The following process types are defined for gfs:
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.
system-config-selinux is a GUI tool available to customize SELinux policy settings.
