Making false positives go away
Network intrusion-detection systems (IDS) have long been recognized as a necessary component of a multilayered security architecture. False positives have long been the bane of IDSs, leading some to even question the value of these products. In the past, many security professionals have found the effectiveness of intrusion detection limited by the need to process a large number of alert notifications, many of which are either incorrect or irrelevant.
However, new network IDS products are appearing that help to tackle the false-positive problem with a smarter detection engine that uses three key technologies: operating system fingerprinting, alert-flood suppression and meta-alert correlation.
