Overview of ASG

The Access Security Gateway (ASG) provides strong authentication for Message Storage Server (MSS) logins. You can administer ASG to protect the server by challenging each potential dial-up session user when the authentication type is set to ASG for that particular login (such as sa or vm). The following table shows each of the available authentication types, including the ASG authentication type, and what information is needed to access the system remotely.

Authentication type Information needed
ASG ASG challenge/response
Password Linux system password
Blocked no remote access allowed

In order to respond to the ASG challenge, the user must have a hand-held device, called the ASG Key. The ASG Key must be set with an ASG secret key number that matches that of the user's ASG secret key number in the server.

For more information about ASG or to start administering ASG, see Administering the Access Security Gateway (ASG).

For more information about ASG and Modular Messaging security, see the ASG Key User Guide, document number 585-212-012.
