Intrusion detection and prevention

Intrusion detection and prevention technology has remained a mainstay at the network perimeter, though predicted to be a dead technology by security experts five to seven years ago. The IPS market is thriving, and enterprises are finding value and regulatory compliance in the platform used to stop malicious attacks at the perimeter. While several firewall technologies are integrating intrusion prevention into their offerings, there has not been a complete shift to this implementation. As with other security areas, there are multiple perspectives that drive technology theory and practice. Typically, the shift to an integrated solution becomes more of an consideration when the network segments requiring protection increase to the extent that it is simply cost prohibitive to deploy standalone intrusion prevention.

Larger enterprises seem to be interested in this capability to reduce cost on a grand scale. Smaller enterprises look at the integrated solutions...
