Allied Telesis Malaysia has announced a new innovation in fibre security called Active Fibre Monitoring, which prevents eavesdropping, said the global IP networking systems provider.
Paul Choy, country sales manager, Allied Telesis Malaysia, said, "With increasing cybercrime and the risk from terrorists and other undesirable elements, Active Fibre Monitoring provides a simple and effective means to identify and take action when communications fibre is tampered with."
Choy said this new patent-pending technology can detect when a cable is being tampered with, and will raise an alarm to warn of a possible security breach.
He said that fibre-optic links were used extensively for long-range data communications and within the LAN environment. One of the perceived advantages of fibre was that eavesdropping on traffic within the cable is not possible.
However, it is now possible to acquire devices that can snoop traffic on fibre cables, said Choy. Allied Telesis therefore developed Active Fiber Monitoring, a technology that detects small changes in the amount of light received on a fibre link. When an intrusion is attempted, the light level changes because some of the light is redirected by the eavesdropper onto another fibre. As soon as this happens, Active Fiber Monitoring detects the intrusion and will raise an alarm. The link can either be shut down automatically, or an operator can be alerted and manually intervene.
"Service providers, financial organisations, government and defence have all expressed a keen interest in this innovative technology," he added.
"The security of data on fibre links used to be taken for granted," said Graham Walker, senior product manager at Allied Telesis. "But companies need to be made aware that it's now very easy to snoop traffic on fibre undetected. Until now, the only countermeasures have been encryption, which is expensive and introduces latency, or sensitive light meters, which are complex to set up and can give false positives. Active Fiber Monitoring is an effective alternative that is easy to use and completely free."
Active Fiber Monitoring is built-in to all Allied Telesis "x" Series switches and firewalls running the latest AlliedWare PlusTM Operating System firmware. It requires the use of DDM-capable optical modules, which are readily available from Allied Telesis.
