Issue 2 June 1999 3-7
The Access Security Gateway consists of two components: 
~
Access Security Gateway Guard
The Access Security Gateway Guard protects the DEFINITY ProLogix 
system from unauthorized access. When users attempt to access the ProLogix 
system remotely, the Access Security Gateway Guard prompts the users to 
enter their login ID and then issues a challenge. Using the Access Security 
Gateway Key, authorized users are able to provide the correct response to the 
challenge issued by the DEFINITY ProLogix system. The challenge issued by 
the DEFINITY ProLogix system and the response that the system expects are 
constantly changed, helping to prevent unauthorized users from accessing the 
DEFINITY ProLogix system.

Access Security Gateway Key
The Access Security Gateway Key enables authorized users to access the 
DEFINITY ProLogix system remotely. When the Access Security Gateway 
issues a challenge, users must enter the challenge into the Access Security 
Gateway Key to receive the correct response to the challenge. The users then 
enter the response to the Access Security Gateway Guard to access the 
system.
