DEFINITY ProLogix Solutions Release 2 Overview
555-235-100 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.
