netlabel_selinux: Security Enhanced Linux Policy for the netlabel processes
NAMEnetlabel_selinux - Security Enhanced Linux Policy for the netlabel processes
Security-Enhanced Linux secures the netlabel 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 netlabel policy is very flexible allowing users to setup their netlabel processes in as secure a method as possible.
The following file types are defined for netlabel:
- Set files with the netlabel_mgmt_exec_t type, if you want to transition an executable to the netlabel_mgmt_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 netlabel policy is very flexible allowing users to setup their netlabel processes in as secure a method as possible.
The following process types are defined for netlabel:
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.
