NAME         top

       securetty_types - The SELinux secure tty type configuration file

DESCRIPTION         top

       The securetty_types file contains a list of types associated to
       secure tty type that are defined in the policy for use by SELinux-
       aware applications.

       selinux_securetty_types_path(3) will return the active policy path
       to this file. The default securetty types file is:
              /etc/selinux/{SELINUXTYPE}/contexts/securetty_types

       Where {SELINUXTYPE} is the entry from the selinux configuration
       file config (see selinux_config(5)).

       selinux_check_securetty_context(3) reads this file to determine if
       a context is for a secure tty defined in the active policy.

       SELinux-aware applications such as newrole(1) use this information
       to check the status of a tty.

FILE FORMAT         top

       Each line in the file consists of the following entry:

              type
                     One or more type entries that are defined in the
                     policy for secure tty devices.

EXAMPLE         top

       # ./contexts/securetty_types
       sysadm_tty_device_t
       user_tty_device_t
       staff_tty_device_t
