processes
DESCRIPTION
Security-Enhanced Linux secures the unconfined processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. uncon‐
fined policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run unconfined with the tightest
access possible.
If you want to allow database admins to execute DML statemen, you must
turn on the sepgsql_unconfined_dbadm boolean.
setsebool -P sepgsql_unconfined_dbadm 1
If you want to allow unconfined users to transition to the Mozilla
plugin domain when running xulrunner plugin-container, you must turn on
the unconfined_mozilla_plugin_transition boolean.
setsebool -P unconfined_mozilla_plugin_transition 1
If you want to allow a user to login as an unconfined domai, you must
turn on the unconfined_login boolean.
setsebool -P unconfined_login 1
If you want to allow unconfined users to transition to the chrome sand‐
box domains when running chrome-sandbo, you must turn on the uncon‐
fined_chrome_sandbox_transition boolean.
setsebool -P unconfined_chrome_sandbox_transition 1
If you want to allow samba to run unconfined script, you must turn on
the samba_run_unconfined boolean.
setsebool -P samba_run_unconfined 1
If you want to allow video playing tools to run unconfine, you must
turn on the unconfined_mplayer boolean.
setsebool -P unconfined_mplayer 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the uncon‐
fined_dbusd_t, unconfined_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
unconfined_dbusd_t, unconfined_t, you must turn on the allow_kerberos
boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the unconfined_dbusd_t,
unconfined_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 unconfined policy is very flexible allowing users to setup
their unconfined processes in as secure a method as possible.
The following file types are defined for unconfined:
unconfined_exec_t
- Set files with the unconfined_exec_t type, if you want to transition
an executable to the unconfined_t domain.
Paths:
/usr/sbin/xrdp, /usr/sbin/xrdp-sesman, /usr/bin/vncserver
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
unconfined policy is very flexible allowing users to setup their uncon‐
fined processes in as secure a method as possible.
The following process types are defined for unconfined:
unconfined_cronjob_t, unconfined_dbusd_t, unconfined_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.
