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.
