Eight sites participated in the second DARPA off-line intrusion detection evaluation in 1999. A test bed generated live background traffic similar to that on a government site containing hundreds of users on thousands of hosts. More than 200 instances of 58 attack types were launched against victim UNIX and Windows NT hosts in three weeks of training data(More)
Eight sites participated in the second DARPA off-line intrusion detection evaluation in 1999. Three weeks of training and two weeks of test data were generated on a test bed that emulates a small government site. More than 200 instances of 58 attack types were launched against victim UNIX and Windows NT hosts. False alarm rates were low (less than 10 per(More)
An important goal of the 1999 DARPA Intrusion Detection Evaluation was to promote the development of intrusion detection systems that can detect new attacks. This thesis describes UNIX attacks developed for the 1999 DARPA Evaluation. Some attacks were new in 1999 and others were stealthy versions of 1998 User-to-Root attacks designed to evade network-based(More)

Abstract The 1999 DARPA Off-Line Intrusion Detection Evaluation provided a standard corpus for evaluating intrusion detection systems. It improved on the 1998 evaluation by providing training data containing no attacks to(More)
A solid corrosion-resistant torsional waveguide of diamond cross section has been developed to sense, online and in real-time, the characteristics of the liquid in which it is submerged. The sensor can measure, among other things, the liquid content of a bubbly medium, the density of adjacent pure liquids, the equivalent density of liquid-vapor mixtures or(More)

In recent days, technology has reached new heights. In the same way malicious programs has also touched the level of sky and the above. Secret information are nowadays stored and managed through high secure sites. However, critical problems like hacking happens due to DDOS(Distributed Denial of Service Attacks) resulting in crashing of website for certain(More)
