Published: 05 December 2007

ID: G00203440

Analyst(s): Daniel Blum


An important part of an organization's security architecture, network intrusion detection and response systems (NIDRS) involve a complex set of choices. Enterprise security teams must determine how to select solutions, decide on appropriate detection and response techniques, and grapple with issues surrounding automated response. In this revised Security and Risk Management Strategies technical position, Analyst Pete Lindstrom augments Trent Henry's guidance for creating a NIDRS architecture.
