NAME

       securetty_types - The SELinux secure tty type configuration file.

DESCRIPTION

       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

       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

       # ./contexts/securetty_types
       sysadm_tty_device_t
       user_tty_device_t
       staff_tty_device_t
