A Layered Approach IPS systems can offer significant benefits, despite their tendency to occasionally misidentify good traffic as an attack and the slight decrease in network performance as packets are checked for potential problems. But that protection needs to be balanced with the costs of keeping the IPS up-to-date with signatures and technology improvements to enable the device to identify attacks. Testing these products reinforces one of my core beliefs: IT managers must take a layered approach to security. Strong firewall protection, a ruthless attention to detail when configuring servers and applications, and user education about the importance of anti-virus and anti-spam usage are part of the security picture.Senior Analyst Cameron Sturdevant can be reached at email@example.com.
