To date, IT security organizations have focused on the network perimeter. However, many of today's attacks are introduced from inside the network. Laptops, PDAs and other devices travel into and out of the network daily, making it possible for legitimate users to infect the network or unwittingly grant attackers access to the network via a Trojan horse or other spyware. For example, many worms have propagated inside the network after being introduced by an internal source. Once a single network device has been infected, the entire network can be compromised very quickly. Fast-spreading worms, often called "flash" or "blitz" worms, can spread worldwide in a matter of minutes! With such costly threats becoming increasingly common, organizations have come to realize that they must provide better defenses against worms, unauthorized access threats and other attacks within their internal network. Check Point InterSpect is an internal security gateway that blocks the spread of worms and attacks inside the network and provides network zone segmentation. Based on Check Point's proven security technologies: INSPECT, Stateful Inspection and Application Intelligence, and SMART (Security Management Architecture), InterSpect is built specifically for internal network security.
