SMART cards, personal identification numbers (PINs) and access codes are the basis of a new SecurID system from SynOptics Communications that is claimed can guarantee the integrity of local area networks providing remote access links. The new security system was designed for SynOptics' own LattisNet family of hubs. It was developed by Security Dynamics Inc, of the United States, and is supposed to ensure that only authorised users gain access to a protected system. ''With the growing number of telecommuters requiring remote access to enterprise networks, our customers have a definite need for higher levels of authentication and bullet-proof security for their networks,'' Gary Law, director of business alliances at SynOptics, said. ''Now . . . our customers have a solution that can defend against hackers who might otherwise infiltrate corporate networks.'' The SecurID system uses a technique known as dynamic two-factor authentication combined with a smart card, a credit-card-sized token that displays a randomly-generated access code that changes every minute. To access a network, users enter a PIN as well as the code displayed on the card's liquid-crystal display. The SecurID module is at the hub and centrally manages and administers pass-codes and access to network resources. James Geary, vice-president of marketing at Security Dynamics, said network access resources were being centralised at the hub because there was now more remote and local network access. Yankee Group, a US information technology research organisation, estimated that computer-related crime accounted for business losses of almost US$5 billion each year.
