Security
In addition to Linux™ authentication and authorization, you can use z/VM® IUCV authorizations, and restrictions on your terminal server and target systems to protect your environment.
Access to Linux is
typically controlled by an authentication program, for example, a
login program. In a terminal server setup, you can also use additional
security mechanisms:
- z/VM IUCV authorizations to control which IUCV connections are possible
- Restrictions on the terminal server to only allow connections to specific target systems
- Restrictions for the terminal devices on the target systems to only allow access from specific z/VM guest virtual machines
How you set up security depends on the specific needs of your installation. This section describes the available control points.
