DESCRIPTION
Security-Enhanced Linux secures the sge processes via flexible manda‐
tory access control.
BOOLEANS
SELinux 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 connect to the network using any TCP por,
you must turn on the sge_domain_can_network_connect boolean.
setsebool -P sge_domain_can_network_connect 1
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
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the
sge_execd_t, sge_job_ssh_t, you must turn on the authlogin_nss‐
witch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
sge_execd_t, sge_job_ssh_t, you must turn on the allow_kerberos bool‐
ean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the sge_execd_t,
sge_job_ssh_t, you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux 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 ls
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:
sge_execd_exec_t
- Set files with the sge_execd_exec_t type, if you want to transition
an executable to the sge_execd_t domain.
sge_job_exec_t
- Set files with the sge_job_exec_t type, if you want to transition an
executable to the sge_job_t domain.
sge_shepherd_exec_t
- Set files with the sge_shepherd_exec_t type, if you want to transi‐
tion an executable to the sge_shepherd_t domain.
sge_spool_t
- Set files with the sge_spool_t type, if you want to store the sge
files under the /var/spool directory.
sge_tmp_t
- 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 permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
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.
COMMANDS
semanage 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 pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
