DCA Increases Security for Remote LAN Access RLN 3.1 Delivers LAN-Based Security, Adds Mac Support.

ALPHARETTA, Ga.--(BUSINESS WIRE)--Dec. 19, 1994--DCA today announced its RLN remote access software now offers remote users an unprecedented level of network security through support for LAN-based security systems implementing the Terminal Access Controller Access Systems (TACACS) standard.

DCA also announced RLN is now available to Apple Macintosh users through support of the Appletalk routing stack and the Apple Remote Access (ARA) 1.0 and 2.0 protocols, allowing remote access to the RLN server for full LAN functionality. In addition to ARA support, RLN offers Macintosh users zone filtering, password aging and changing and LAN-access group time restrictions.

"The addition of the Apple Remote Access protocols rounds out RLN's desktop platform support," said David Gould, president of DCA's Remote Access Division. "RLN already was accepted by the Global 5000 market as providing the best security capabilities for remote. This release expands our comprehensive security facilities while meeting our commitment to open standards demanded by our customers."

He added that earlier this fall, DCA announced support for an OS/2 client, an addition to existing Windows and DOS clients.

RLN's support of TACACS enables the RLN server to talk transparently to security servers across the network to provide user database authentication. That capability allows enterprises to use state-of-the-art dynamic security systems to provide remote users unlimited access to information resources while providing unprecedented protection of corporate data assets.

LAN-based security products supporting the TACACS protocol, including ACE/Server Authentication from Security Dynamics, Inc. and SafeWord from Enigma Logic Inc., generate unique numerical passwords on the server every few seconds.

Each remote user has a credit card-size "token," or software on their remote computers that simultaneously generate the same numbers. After the user enters the correct code in the remote client software, the RLN server passes on the login request to the security server for authentication before network access is granted.

John Muir, president of Enigma Logic, emphasized that the combination of DCA's RLN product and Enigma Logic's SafeWord Remote software can substantially reduce the cost of network security for DCA customers. "Multiple RLN installations can communicate with a single SafeWord Remote server for authentication services, thus substantially reducing the cost of network security," Muir said.

"The savings are even greater when a customer chooses to use a SafeWord SofToken instead of the standard hardware types of password generators."

RLN 3.1 extends networking environments through corporate applications such as E-mail and databases to remote and mobile PC users, allowing those users to access the network as if it is a locally connected user, providing effective remote connectivity that is essential for an enterprise wide system.

DCA's RLN products offer the widest range of configuration schemes and communications protocol support in the industry. System sizes range from two-to 32-port configurations and RLN has a Windows-based SNMP Manager for easy configuration and management plus full support for Token-Ring and Ethernet topologies on all major network operating systems, including NetWare, LAN Manager, LAN Server, Banyan and Windows for Workgroups.

RLN 3.1 is available now for both Ethernet and Token-Ring through DCA's standard distribution network. The suggested retail prices for RLN Version 3.1 range from $895 for a two-port configuration to $14,395 for a 32-port configuration. Pricing outside North America depends on the local market.
