A safe communication infrastructure is critical to maintaining the prosperity and pre-eminence of the United States in the 21(st) century. intrusiondetection systems (IDS) help identify and respond to malicious activity targeted at computing and networking resources. In this paper, we shall first give an overview of intrusiondetection concepts and taxonomy. Next, we introduce and discuss several commercial and public-domain IDS's available today. Then, we describe recent developments in conventional intrusiondetection: Distributed, modular system which include both anomaly and misuse detection. Lastly, we give a peek at the new breed of pro-active, preventative tools. These so-called Delphic tools identify the threats and risks in the very early attack stages;ideally, even before an attack takes place. Examples mentioned are quantitative security risk analysis and Bayesian multiple hypothesis tracking.
