Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In recent years, Wireless Sensor Networks (WSNs) and Wireless Local Area Networks (WLANs) have witnessed dramatic development due to the variety of applications and cost effectiveness in network deployment. However, we believe the wide application of both WSNs and WLANs in the future is contingent on the security of the networks. Considering that wireless nodes in both WSNs and WLANs are less powerful and more vulnerable than their wired counterparts, we focus on studying the attacks targeting on wireless nodes and their defenses in this dissertation. First, we study node destroying attack in WSNs and its defense. In search based node destroying attack we model, the attacker walks through the network using signal detecting equipment to locate active sensors, and then destroys them. To defend against such attack, we design a defense approach based on sacrificial nodes. The core principle of our defense is to trade short term local coverage for long term global coverage through the sacrificial node assisted attack notification and sensors states switching. Second, we study node penetrating attack in WSNs and its defense. In node penetrating attack, the attacker is able to penetrate a certain percentage of the nodes in the network, and access all the secret information stored in the penetrated nodes. We propose a defense methodology called network decoupling to deal with such attack, based on which we design two new key management protocols, i.e., RKP-DE and RKP-DEA. Third, we study node spoofing attack in IEEE 802.11 based WLANs. Such attack takes advantage of the security vulnerabilities of a special but important type of frames in 802.11 WLANs called null data frame. We first model and implement the node spoofing attack, and evaluate its effectiveness based on extensive experiments. Then, we design and implement our defense mechanism based on embedded temporal information in the genuine null data frames. With the popularity and wide applications of WSNs and WLANs, security is becoming increasingly critical to the success of such wireless networks. We hope that our work in this dissertation can provide strong foundations and further motivate other researchers to explore this area in the future.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses and summarizes current research issues, identifies challenges, and outlines future directions for proactive and dynamic network defense. This book also presents the latest fundamental research results toward understanding proactive and dynamic network defense by top researchers in related areas. It includes research results that offer formal frameworks to define proactive and dynamic network defense, and develop novel models to analyze and evaluate proactive designs and strategies in computer systems, network systems, cyber-physical systems and wireless networks. A wide variety of scientific techniques have been highlighted to study these problems in the fundamental domain. As the convergence of our physical and digital worlds grows fast pace, protecting information systems from being tampered or unauthorized access is becoming one of the most importance issues. The traditional mechanisms of network defense are built upon a static, passive, and reactive nature, which has insufficient to defend against today's attackers that attempt to persistently analyze, probe, circumvent or fool such mechanisms. It has not yet been fully investigated to address the early stage of “cyber kill chain” when adversaries carry out sophisticated reconnaissance to plan attacks against a defense system. Recently, proactive and dynamic network defense has been proposed as an important alternative towards comprehensive network defense. Two representative types of such defense are moving target defense (MTD) and deception-based techniques. These emerging approaches show great promise to proactively disrupt the cyber-attack kill chain and are increasingly gaining interest within both academia and industry. However, these approaches are still in their preliminary design stage. Despite the promising potential, there are research issues yet to be solved regarding the effectiveness, efficiency, costs and usability of such approaches. In addition, it is also necessary to identify future research directions and challenges, which is an essential step towards fully embracing proactive and dynamic network defense. This book will serve as a great introduction for advanced-level computer science and engineering students who would like to start R&D efforts in the field of proactive and dynamic network defense. Researchers and professionals who work in this related field will also find this book useful as a reference.
Download or read book Defense Against Node Compromise in Sensor Network Security written by Xiangqian Chen and published by LAP Lambert Academic Publishing. This book was released on 2009-06-09 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Security issues in Wireless sensor networks (WSNs) mainly come from attacks. In general, the attacks in WSNs can be classified as external attacks and internal attacks. In an external attack, the attacking node is not an authorized participant of the sensor network. Cryptography and other security methods can prevent some of external attacks. However, node compromise, the major and unique problem that leads to internal attacks, will eliminate all the efforts. Knowing the probability of node compromise will help systems to detect and defend against it. Although there are some approaches that can be used to detect and defend against node compromise, few of them have the ability to estimate the probability of node compromise. Hence, we develop basic uniform, basic gradient, intelligent uniform and intelligent gradient models for node compromise distribution in order to adapt to different application environments. These models allow systems to estimate the probability of node compromise. Applying these models in system security designs can improve system security and decrease the overheads nearly in every security area.

Available in PDF, EPUB and Kindle. Book excerpt: We study the problem of characterizing the wormhole attack, an attack that can be mounted on a wide range of wireless network protocols without compromising any cryptographic quantity or network node. Making use of geometric random graphs induced by the communication range constraint of the nodes, we present the necessary and sufficient conditions for detecting and defending against wormholes. Using our theory, we also present a defense mechanism based on local broadcast keys. We believe our work is the first one to present analytical calculation of the probabilities of detection. We also present simulation results to illustrate our theory.

As a matter of fact, next-generation emerging networks are exploiting their numerous applications in both military and civil fields. For most applications, it is important to guarantee high security of the deployed network in order to defend against attacks from adversaries, as well as the privacy intrusion. The key target in the development of next-generation wireless networks is to promote the integration of the human, cyber, and physical worlds. Previous work in Cyber Physical Systems (CPS) considered the connection between the cyber world and the physical world. In the recent studies, human involvement brings new channels and initiatives in this interconnection. In this integration process, security and privacy are critical issues to many wireless network applications, and it is a paramount concern for the growth of next-generation wireless networks. This is due to the open nature of wireless communication and the involvement of humans. New opportunities for tackling these security and privacy issues in next-generation wireless networks will be achieved by leveraging the properties of interaction among human, computers and things.

Download or read book Defending Wireless Networks from Radio Interference Attacks written by and published by . This book was released on 2007 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless networks are built upon a shared medium that makes it easy for adversaries to conduct radio interference, or jamming attacks, which effectively cause a denial of service (DoS) of either transmission or reception functionalities. These attacks can be easily accomplished by an adversary by either bypassing MAC-layer protocols, or emitting a radio signal targeted at jamming a particular channel. In this thesis, we examine the issue of jamming wireless networks, and sensor networks in particular, by studying both the attack and defense side of the problem. On the attack side, we present four different jamming attack models that can be used by an adversary to disable the operation of a wireless network, and evaluate their effectiveness in terms of how each method affects the ability of a wireless node to send and receive packets. In order to cope with the problem of jamming, we discuss a two-phase strategy involving the diagnosis of the attack, followed by a suitable defense strategy. For detection, we show that single measurement statistics are not enough to reliably classify the presence of a jamming attack, and propose multimodal detection methods. To cope with jamming, we propose a technique, channel surfing, which involves evading the interferer in the spectral domain. Several different channel surfing models are presented, and we evaluate their effectiveness using a testbed of MICA2 motes. Beyond channel surfing, we overview a second defense strategy whereby it is possible to establish a low data rate jamming resistant communication channel by modulating the interarrival times between jammed packets.

Download or read book System and Control Engineering Approaches to Some Network Vulnerability Problems written by Xiaoyi Wu and published by . This book was released on 2006 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Security and performance optimization are two important issues in communication networks. This dissertation focus on two kinds of network attacks: Denial of Service (DoS) attacks in the Internet and energy-depletion attacks in wireless sensor networks. Defense strategies against them are given that can achieve a good balance between security and performance. DoS attacks are designed to prevent the targeted computer from responding to legitimate connections, and can cause great damage to the current Internet. To defend against DoS attacks, a feedback-control-based strategy is proposed, which consists of a queue-content-based local detection mechanism to detect potential attacks and feedback control mechanism using a node's queue content to control the sending rate of the upstream nodes. Simulation results are included to illustrate the effectiveness of the proposed strategy in detecting DoS attacks at an early stage and reducing the damage to a desired degree. In order to optimize the performance of a network while it is under a DoS attack, this dissertation uses a stochastic fluid model of the target node, and a stochastic gradient-based algorithm to do on-line optimization, in which perturbation analysis techniques are used to obtain the necessary gradient estimates for implementing such an algorithm. Simulation results show that this approach can optimize a network's performance while it is under attack. Next, energy-depletion attacks is investigated, which can easily drain the whole sensor network's main resource, i.e. energy, and eliminate the sensor network's ability to perform its function. In order to defend against such attacks and maximize the lifetime of a network, this dissertation adopts probabilistic routing and use an optimal control approach to control and optimize the network performance. It is proved that in a fixed topology case there exists an optimal policy consisting of time-invariant routing probabilities that may be obtained by solving a set of relatively simple non-linear programming problems. Numerical examples are included to contrast the maximum lifetime obtained from proposed strategy to that resulting from alternative routing policies that are commonly adopted. The routing policy proposed in this thesis provides a good balance between security and performance in a wireless sensor network.
