Most intrusion detection systems available today are using a single audit source for detecting all attacks, even though attacks have distinct manifestations in different parts of the system. In this paper we carry out a theoretical investigation of the role of the audit source for the detection capability of the intrusion detection system (IDS). Concentrating on web server attacks, we examine t...
Intrusion Detection Systems (IDS) have nowadays become a necessary component of almost every security infrastructure. So far, many different approaches have been followed in order to increase the efficiency of IDS. Swarm Intelligence (SI), a relatively new bioinspired family of methods, seeks inspiration in the behavior of swarms of insects or other animals. After applied in other fields with s...
In Mobile Ad Hoc Network (MANET), Multimodal Biometric technology plays a vital role in giving security between user-to-device authentications. This paper concentrates on the Intrusion Detection and authentication with data fusion in MANET. To overcome the fault in unimodal biometric systems, Multimodal biometrics is set out to work with Intrusion Detection Systems. Each and every device has di...
Intrusion detection is the process of monitoring and analyzing the events occurring in a computer system in order to detect signs of security problems. The problem of intrusion detection can be solved using anomaly detection techniques. For instance, one is given a set of connection data belonging to different classes (normal activity, different attacks) and the aim is to construct a classifier...
In our world of ever-increasing Internet connectivity, there is an on-going threat of intrusion or denial of service attacks. These intrusions may bring all kinds of misuses. Intrusion Detection Systems (IDS) play a very important role in the security of today's networks by detecting when an attack is happening. IDS have evolved into an integral part of network security which monitors the netwo...
Bio: Christopher Wee is a Researcher in the Computer Security Group at the University of California, Davis, Computer Science Department. His current research interests are intrusion detection, security auditing and Formal policy specifications. Chris has participated in three intrusion detection systems projects: DIDS, a LAN intrusion detection system, GrIDS: a wide-area IDS, and LAFS: a file-s...
DIDMA (Distributed Intrusion Detection using Mobile Agents) is a novel architecture in the field of IDS (Intrusion Detection Systems), utilizing an agent-based approach in order to realize a distributed framework. The novelty in this architecture is the employment of mobile agents as its auditing components. This novel approach overcomes certain problems associated with traditional designs in I...
In this paper we will demonstrate how one can model and analyse Intrusion Detection Systems (IDSs) and their environment using the process algebra Communicating Sequential Processes (CSP) [11, 21] and its model checker FDR [9]. An Intrusion Detection System (IDS) is a system that detects abuses, misuses and unauthorised uses in a network. We show that this analysis can be used to discover two a...
Storage-based intrusion detection allows storage systems to watch for data modifications characteristic of system intrusions. This enables storage systems to spot several common intruder actions, such as adding backdoors, inserting Trojan horses, and tampering with audit logs. Further, an intrusion detection system (IDS) embedded in a storage device continues to operate even after client system...
in recent years mobile networks have expanded dramatically, compared with other wireless networks. routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. in this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...
