prelude_lml_selinux(8) - Linux man page

Name

prelude_lml_selinux - Security Enhanced Linux Policy for the prelude_lml processes

Description

Security-Enhanced Linux secures the prelude_lml processes via flexible mandatory access control.

The prelude_lml processes execute with the prelude_lml_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep prelude_lml_t

Entrypoints

The prelude_lml_t SELinux type can be entered via the "prelude_lml_exec_t" file type. The default entrypoint paths for the prelude_lml_t domain are the following:"

/usr/bin/prelude-lml

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 prelude_lml policy is very flexible allowing users to setup their prelude_lml processes in as secure a method as possible.

The following process types are defined for prelude_lml:

prelude_lml_t

Note: semanage permissive -a prelude_lml_t

can be used to make the process type prelude_lml_t permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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 prelude_lml policy is very flexible allowing users to setup their prelude_lml processes in as secure a method as possible.

The following file types are defined for prelude_lml:

prelude_lml_exec_t

- Set files with the prelude_lml_exec_t type, if you want to transition an executable to the prelude_lml_t domain.

prelude_lml_tmp_t

- Set files with the prelude_lml_tmp_t type, if you want to store prelude lml temporary files in the /tmp directories.

prelude_lml_var_run_t

- Set files with the prelude_lml_var_run_t type, if you want to store the prelude lml files under the /run directory.

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.

Managed Files

The SELinux process type prelude_lml_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

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 policy modules.

system-config-selinux is a GUI tool available to customize SELinux policy settings.
