SonicWALL has developed a new deep packet inspection technique that does not require the analysis engine to play an entire message stream before it can perform its analysis.
The emerging popularity of virtual computing has very few blemishes considering its youth. One of those, unfortunately, is security both of the underlying operating environment and of the individual virtual machines.
The VPN Firewall Brick is a selective, but major upgrade over the stateful inspection firewall commonly deployed in the late 1990s. It is an appliance that offers many interfaces. The core of the Brick is a stateful inspection engine. This has been allowing administrators to more easily manage security for more than a decade.
The first conference I attended was a Check Point conference in 1996. The company pioneered stateful inspection, and it seemed that a good portion of the conference was devoted to explaining the new technology. Since Check Point was the leader in 1996, the question hovers: what has the company done to handle emerging threats.
