Dial-up ports provide access to data networks and computers that contain critical
data and software applications. While these ports help to improve productivity and
increase customer satisfaction, they also provide potential access to hackers.
The “key and lock” authentication process uses a sophisticated dynamic
challenge/response technique to assist you in preventing unauthorized access to
your administration and maintenance ports. This authentication process is as
follows:
■ The lock answers the incoming call destined for the dial-up modem port. It
generates a dynamic challenge, unique to every call, and transmits it to the
RPSD installed at the calling end. The lock and key must be initialized with
the same secret encryption key value. This secret encryption key has
approximately 70 quadrillion combinations.
■ When the RPSD key receives the challenge, it generates a response using
the secret encryption key. It then transmits the expected response back to
the RPSD lock. If the RPSD lock successfully authenticates the response,
it provides ringing to the terminating modem and the call completes. The
RPSD terminates a call immediately if any step in the challenge/response
authentication process is not completed successfully.
The RPSD helps to:
■ Protect remote locations that communicate with a central network via
dial-up lines
■ Safeguard companies that remotely administer PBX and voice mail
systems
■ Ensure that critical network routing information and PBX feature
translations are not compromised
■ control access of dial-up ports by remote maintenance or service personnel
Key and lock features
■ Uses randomly-generated encrypted data to perform key/lock
authentication handshake.
■ Time of Day/Day of Week restrictions can control key access to locks. Each
user profile can have up to 14 restrictions set.
■ History logs provide audit trails of the last 500 administrative changes,
accesses, and failures.
■ System administration provides menu-driven commands with online help
and security options for administrative access.
■ Self-check and built-in diagnostics enable simple and fast problem
diagnosis.
