Worms, viruses and denial of service attacks continue to plague internet users, and businesses will continue to protect themselves by buying new network intrusion prevention systems, according to In-Stat/MDR.

The market researcher said the world market for intrusion prevention and detection systems would reach $1.4bn (£720m) by 2008, up from $541m in 2003. Most of the revenue growth will be through hardware-based network intrusion prevention appliances.

"Intrusion prevention systems are a proactive technology that can block attacks before they reach the intended target," said In-Stat/MDR analyst Victoria Fodale. "Besides protecting the network from undesired access, next-generation intrusion prevention products also safeguard the network from malicious content and the inappropriate traffic rates that precede worm or denial of service attacks."

In-Stat also found that four in five companies now used intrusion prevention systems inline with blocking protection and that 19% of intrusion prevention systems were deployed at critical segments within the network.

For companies buying intrusion prevention systems the three factors that influence purchasing decisions are increased functionality, business liability and improved network performance.
