Internal versus external security

When you start the Classic Interface, it checks if an exit routine for an external security package is installed.

You can use external security alone, internal security alone, or external security on some commands and internal on others.

Important: The use of the term authorized implies APF authorization.

• If the exit routine exists, it gets control for the commands that are marked for external security. It determines authorization through the external security package. If external security allows the command, the Classic Interface does not check internal security.
• If external security is not used for the command, internal security takes effect. The Classic Interface includes specific authorized commands. They require an internal security password for execution.
