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
