An overview of anomaly detection techniques: Existing solutions and latest technological trends

Java is a programming language with features not found in traditional languages, such as platform independence and dynamic loading. Because of this, the use of Java is extending and it is beginning to be used in many new environments. In particular,…

We present a comparative evaluation of a large number of anomaly detection techniques on a variety of publicly available as well as artificially generated data sets. Many of these are existing techniques while some are slight variants and/or…

In this paper, a tutorial overview on anomaly detection for hyperspectral electro-optical systems is presented. This tutorial is focused on those techniques that aim to detect small man-made anomalies typically found in defense and surveillance…

Web site defacement, the process of introducing unauthorized modifications to a web site, is a very common form of attack. Detecting such events automatically is very difficult because web pages are highly dynamic and their degree of dynamism, as…

In this paper, the emphasis is placed on the evaluation of the impact of various packet sampling techniques that have been proposed in the PSAMP IETF draft, on two widely used anomaly detection approaches. More specifically, we evaluate the behavior…

There is usually a large amount of redundancy in hyperspectral pixels as they are acquired in hundreds of narrow and continuous spectral bands. Numerous techniques have been proposed to reduce the dimensionality of hyperspectral data in order to…

Much data access occurs via HTTP, which is becoming a universal transport protocol. Because of this, it has become a common exploit target and several HTTP specific IDSs have been proposed as a response. However, each IDS is developed and tested…

Anomaly detection is an important and indispensable aspect of any computer security mechanism. Ad hoc and mobile networks consist of a number of peer mobile nodes that are capable of communicating with each other absent a fixed infrastructure.…

This paper presents existing solutions to protect communications within a System-on-Chip which uses a Networkon- Chip. We first present an existing bus-based solution and compare this approach to NoC-based solutions. Two types of techniques are…

The assessment of malingering can pose a challenging task to the forensic evaluator. However, with the increasing role of mental health professionals in evaluations for forensic purposes such as competency, insanity, workers' compensation, and…
