Should you outsource IDS?

Outsourcing intrusion detection is gaining in popularity; nearly all IDS vendors now offer services as well as products. Peter Lindstrom, an analyst at Hurwitz Group Inc. in Framingham, Mass., says outsourcing an IDS can be beneficial because "you get a dispassionate group of people" deciding the urgency of threats. These decisions can be politically charged when performed in-house, such as when IT wants to shut down a production server.

While outsourcing IDS requires less investment upfront, it's more expensive in the long run, practitioners say. And sharing critical data with an outsourcer requires trust and confidence in the vendor's abilities -- and viability.
