Check Point’s InterSpect appliance is an internal firewall capable of monitoring internal network traffic at packet level, isolating machines or network segments where it detects trouble.
Although the company claims the idea is new, it has been around in different forms for some time.
However, the problem InterSpect is looking to address should be well-known to network administrators the world over.
“Most worm attacks come from people inside the network,” said Check Point’s David Aminzade. “InterSpect will notify the system administrators and users, telling them a virus has been detected.”
Aminzade said that all it takes is one worm-infected laptop to be plugged into the network at the end of its travels and that network can then become the launch pad for further mayhem. Since today’s worms spread at incredible speed, there is a need for wire-speed security appliances monitoring traffic inside the network.
In Check Point’s view, none of the existing security technologies - anti-virus software, intrusion detection systems, and secure switches - can secure networks properly against internal threats such as worms.
An update service, SmartDefense, is also available for customers wanting pre-emptive defence against emerging vulnerabilities.
InterSpect comes in three versions of increasing throughput, which range in price from $9,000 to around $39,000.
