NAMEsge_selinux - Security Enhanced Linux Policy for the sge processes
SELinux Linux secures sge (Policy for gridengine MPI jobs) processes via flexible mandatory access control.
BOOLEANSSELinux policy is customizable based on least access required. sge policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sge with the tightest access possible.
If you want to allow sge to access nfs file systems, you must turn on the sge_use_nfs boolean.
setsebool -P sge_use_nfs 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 sge policy is very flexible allowing users to setup their sge processes in as secure a method as possible.
The following file types are defined for sge:
- Set files with the sge_execd_exec_t type, if you want to transition an executable to the sge_execd_t domain.
- Set files with the sge_job_exec_t type, if you want to transition an executable to the sge_job_t domain.
- Set files with the sge_shepherd_exec_t type, if you want to transition an executable to the sge_shepherd_t domain.
- Set files with the sge_spool_t type, if you want to store the sge files under the /var/spool directory.
- Set files with the sge_tmp_t type, if you want to store sge temporary files in the /tmp directories.
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 sge policy is very flexible allowing users to setup their sge processes in as secure a method as possible.
The following process types are defined for sge:
sge_execd_t, sge_job_ssh_t, sge_shepherd_t, sge_job_t
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.
