getty_selinux(8) - Linux man page

Name

getty_selinux - Security Enhanced Linux Policy for the getty processes

Description

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

The getty processes execute with the getty_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 getty_t

Entrypoints

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

/sbin/.*getty

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

The following process types are defined for getty:

getty_t

Note: semanage permissive -a getty_t

can be used to make the process type getty_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 getty policy is very flexible allowing users to setup their getty processes in as secure a method as possible.

The following file types are defined for getty:

getty_etc_t

- Set files with the getty_etc_t type, if you want to store getty files in the /etc directories.

getty_exec_t

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

getty_lock_t

- Set files with the getty_lock_t type, if you want to treat the files as getty lock data, stored under the /var/lock directory

getty_log_t

- Set files with the getty_log_t type, if you want to treat the data as getty log data, usually stored under the /var/log directory.

getty_tmp_t

- Set files with the getty_tmp_t type, if you want to store getty temporary files in the /tmp directories.

getty_var_run_t

- Set files with the getty_var_run_t type, if you want to store the getty 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 getty_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.
