Intrusion Detection and Prevention Systems



Karen A. Scarfone, Peter M. Mell


Intrusion detection is the process of monitoring the events occurring in a computer system or network and analyzing them for signs of possible incidents. An intrusion detection and prevention system (IDPS) is software that automates the intrusion detection process and can also attempt to stop possible incidents. This chapter provides an overview of IDPS technologies. It explains the key functions that IDPS technologies perform and the detection methodologies that they use. Next, it highlights the most important characteristics of each of the major classes of IDPS technologies. The chapter also discusses IDPS interoperability and complementary technologies.
