GDC's Secure Access Provides Protection Against Malicious or Unauthorized Tampering of Analog NetworksGDC's Secure Access Modem

General DataComm, Inc. (GNRD) announces the addition of
Secure Access to its family of V.34 modems. GDC's new Secure Access
Modem (SAM) now provides User Authentication and AES Data Encryption
protection from malicious or unauthorized users on network equipment
connected via the PSTN.
   The Secure Access Modem (SAM) and Secure Access Control System
(SAC) have been a collaborative development between General DataComm
Inc. of Naugatuck, CT, Bell Canada, and SecureNex Systems of Ottawa,
Ontario Canada for secure out-of-band management of network equipment.
In a SAC system, GDC's family of NEBS Level III Certified, SpectraComm
V.34 Modems integrate seamlessly with SecureNex Systems, Secure Access
Servers and Client software. GDC's AES encryption and authentication
capable SAM modems enable secure access to local and remote network
equipment via a dial-up connection, thereby addressing any data
security exposure.
   "GDC's Secure Access Modem offers our customers in the U. S. and
Canada a higher level of network security," said George Best, vice
president sales and marketing at General DataComm. "GDC SpectraComm
V.34 modems equipped with the Secure Access Modem option deliver added
protection for corporate and personal information and provided the
highest level of modem security available today."
   The Secure Access Modem (SAM) in conjunction with a Secure Access
Controller (SAC) , authenticates remote users attempting to access
protected network equipment, such as switches, routers and
multiplexers. The Authentication Server generates public and private
keys, which are exchanged by the modem and remote user's client
software. Each connection sets up a secure tunnel that passes
AES-Encrypted data to the authorized user. When a user terminates a
session, the Secure Access Modem requests a connection to the
authentication Server to obtain a new private key, thus preventing
further access from the previous remote user or intruder.
   General DataComm has been designing rigorous security solutions
into its systems and products for over 30 years to meet the mandatory
requirements for mission-critical network access applications used by
service providers, enterprise users, and government agencies.
   GDC's new Secure Access Modem feature is available now. Customers
who already have SpectraComm V.34 modems in their networks can
purchase a Secure Access Modem firmware upgrade.
