Secure Unit Authentication (SUA)-Supports the ASA 5505 authentication with dynamically generated authentication credentials or with static credentials to be entered at tunnel initiation. With SUA enabled, the user must manually trigger the IKE tunnel using a browser or an interactive CLI.
â¢Individual User Authentication (IUA)-Enables static and one-time password authentication of individual clients on the inside network. IUA and SUA are independent of each other; they work in combination or isolation from each other.
