Intrusion Detection: The Old Guard Dog Learns Some New Tricks
How to Increase the Reliability of Your IT Infrastructure Using Predictive Analytics REGISTER >
Intrusion detection systems used to be a must-have for technology security managers. But as threats to the network evolved, so did the tools that counter them. Today, in-house security experts are building defense systems with multiple components--detection and prevention tools, firewalls and fire doors--to ward off threats like worms, spyware, viruses and hacker attacks.
With that advanced mind-set come advanced tools. No longer are software and appliances simply sniffing out or stopping unwanted traffic; vendors today are integrating these capabilities into product suites as well as their network equipment.

Intrusion detection systems aren't too common today as standalone security devices, but some loyal users say the technology shouldn't be taken for granted. But others believe detection is just one piece of the puzzle and that prevention is the key to protecting networks today.
