Lucent representative.

Access Security Gateway (ASG) is an authentication interface used to protect the 
system administration and maintenance ports and logins on DEFINITY ECS. 
ASG uses a challenge and response protocol to validate the user and reduce 
unauthorized access. 

You can administer ASG authentication on either a port type or login ID. If you 
set ASG authentication for a specific port, it restricts access to that port for all 
logins. If you set ASG authentication for a specific login ID, it restricts access to 
that login, even when the port is not administered to support ASG. 

Authentication is successful only when DEFINITY ECS and ASG communicate 
with a compatible key. You must maintain consistency between the Access 
Security Gateway Key and the secret key assigned to the DEFINITY ECS login. 
For more information about ASG, refer to 

‘‘Using access security gateway’’ on 

page 319

.

Before you can log into the system with ASG authentication, you need an Access 
Security Gateway Key, and you need to know your personal identification number 
(PIN). The Access Security Gateway Key must be pre-programmed with the same 
secret key (such as, ASG Key, ASG Passkey, or ASG Mobile) assigned to the 
DEFINITY ECS login. 

Verify that the Access Security Gateway (ASG) field on the System-Parameters 
Customer Options screen is set to 

. If not, contact your Lucent representative.
