run_selinux: Security Enhanced Linux Policy for the run processes
NAMErun_selinux - Security Enhanced Linux Policy for the run processes
Security-Enhanced Linux secures the run processes via flexible mandatory access control.
BOOLEANSSELinux policy is customizable based on least access required. run policy is extremely flexible and has several booleans that allow you to manipulate the policy and run run with the tightest access possible.
If you want to allow Apache to run in stickshift mode, not transition to passenge, you must turn on the httpd_run_stickshift boolean.
setsebool -P httpd_run_stickshift 1
If you want to allow xend to run qemu-dm. Not required if using paravirt and no vfb, you must turn on the xend_run_qemu boolean.
setsebool -P xend_run_qemu 1
If you want to allow xend to run blktapctrl/tapdisk. Not required if using dedicated logical volumes for disk images, you must turn on the xend_run_blktap boolean.
setsebool -P xend_run_blktap 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 users to login using a sssd serve for the run_init_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the run_init_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 run_init_t, you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 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 run policy is very flexible allowing users to setup their run processes in as secure a method as possible.
The following file types are defined for run:
- Set files with the run_init_exec_t type, if you want to transition an executable to the run_init_t domain.
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 run policy is very flexible allowing users to setup their run processes in as secure a method as possible.
The following process types are defined for run:
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.
