Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Malware, or malicious software such as viruses, worms, trojan horses or rootkits, pose a grave challenge to the computer user community by obtaining unauthorized access to computer resources. Among various malware, worms interest computer security researchers immensely due to their ability to infect millions of computers in a short period of time and cause hundreds of millions of dollars in damage. Unlike other malware, worms can replicate themselves over the Internet without requiring any human involvement, which makes their damage potential very high. Security researchers strive to prevent, detect and contain worms, as well as model their propagation patterns over the Internet. Our study is primarily directed at effective detection, propagation modeling and design of worms. First, we work towards devising a detection mechanism for an advanced worm called ASCII worm which has a very high damage potential due to its ability to compromise servers that are otherwise not vulnerable to common worms. Second, we derive an exact analytical model for the propagation of permutation-scanning worms, a class of worms that employ a sophisticated propagation strategy called permutation scanning. Finally, we re-examine the classical worm propagation models in light of the pseudo-random nature of the output generated by the random number generators used by the worms, and design a worm that exploits the pseudo-randomness to achieve an optimal scanning strategy with high speed of infection, fault tolerance and low detectability.

Available in PDF, EPUB and Kindle. Book excerpt: As computer and communication networks become prevalent, the Internet has been a battlefield for attackers and defenders. One of the most powerful weapons for attackers is the Internet worm. Specifically, a worm attacks vulnerable computer systems and employs self-propagating methods to flood the Internet rapidly. The objective of this research is to characterize worm attack behaviors, analyze Internet vulnerabilities, and develop effective countermeasures. More specifically, some fundamental factors that enable a worm to be designed with advanced scanning methods are presented and investigated through mathematical modeling, simulations, and real measurements.

Download or read book Malicious Attack Propagation and Source Identification written by Jiaojiao Jiang and published by Springer. This book was released on 2018-11-20 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers and makes four major contributions: 1) analyzing and surveying the pros and cons of current approaches for identifying rumor sources on complex networks; 2) proposing a novel approach to identify rumor sources in time-varying networks; 3) developing a fast approach to identify multiple rumor sources; 4) proposing a community-based method to overcome the scalability issue in this research area. These contributions enable rumor source identification to be applied effectively in real-world networks, and eventually diminish rumor damages, which the authors rigorously illustrate in this book. In the modern world, the ubiquity of networks has made us vulnerable to various risks. For instance, viruses propagate throughout the Internet and infect millions of computers. Misinformation spreads incredibly fast in online social networks, such as Facebook and Twitter. Infectious diseases, such as SARS, H1N1 or Ebola, have spread geographically and killed hundreds of thousands people. In essence, all of these situations can be modeled as a rumor spreading through a network, where the goal is to find the source of the rumor so as to control and prevent network risks. So far, extensive work has been done to develop new approaches to effectively identify rumor sources. However, current approaches still suffer from critical weaknesses. The most serious one is the complex spatiotemporal diffusion process of rumors in time-varying networks, which is the bottleneck of current approaches. The second problem lies in the expensively computational complexity of identifying multiple rumor sources. The third important issue is the huge scale of the underlying networks, which makes it difficult to develop efficient strategies to quickly and accurately identify rumor sources. These weaknesses prevent rumor source identification from being applied in a broader range of real-world applications. This book aims to analyze and address these issues to make rumor source identification more effective and applicable in the real world. The authors propose a novel reverse dissemination strategy to narrow down the scale of suspicious sources, which dramatically promotes the efficiency of their method. The authors then develop a Maximum-likelihood estimator, which can pin point the true source from the suspects with high accuracy. For the scalability issue in rumor source identification, the authors explore sensor techniques and develop a community structure based method. Then the authors take the advantage of the linear correlation between rumor spreading time and infection distance, and develop a fast method to locate the rumor diffusion source. Theoretical analysis proves the efficiency of the proposed method, and the experiment results verify the significant advantages of the proposed method in large-scale networks. This book targets graduate and post-graduate students studying computer science and networking. Researchers and professionals working in network security, propagation models and other related topics, will also be interested in this book.

Download or read book On Countermeasures of Worm Attacks Over the Internet written by Wei Yu and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Worm attacks have always been considered dangerous threats to the Internet since they can infect a large number of computers and consequently cause large-scale service disruptions and damage. Thus, research on modeling worm attacks, and defenses against them, have become vital to the field of computer and network security. This dissertation intends to systematically study two classes of countermeasures against worm attacks, known as traffic-based countermeasure and non-traffic based countermeasure. Traffic-based countermeasures are those whose means are limited to monitoring, collecting, and analyzing the traffic generated by worm attacks. Non-traffic based countermeasures do not have such limitations. For the traffic-based countermeasures, we first consider the worm attack that adopts feedback loop-control mechanisms which make its overall propagation traffic behavior similar to background non-worm traffic and circumvent the detection. We also develop a novel spectrumbased scheme to achieve highly effective detection performance against such attacks. We then consider worm attacks that perform probing traffic in a stealthy manner to obtain the location infrastructure of a defense system and introduce an information-theoretic based framework to obtain the limitations of such attacks and develop corresponding countermeasures. For the non-traffic based countermeasures, we first consider new unseen worm attacks and develop the countermeasure based on mining the dynamic signature of worm programs0́9 run-time execution. We then consider a generic worm attack that dynamically changes its propagation patterns and develops integrated countermeasures based on the attacker's contradicted objectives. Lastly, we consider the real-world system setting with multiple incoming worm attacks that collaborate by sharing the history of their interactions with the defender and develop a generic countermeasure based on establishing the defender's reputation of toughness in its repeated interactions with multiple incoming attackers to optimize the long-term defense performance. This dissertation research has broad impacts on Internet worm research since this work is fundamental, practical and extensible. Our developed framework can be used by researchers to understand key features of other forms of new worm attacks and develop countermeasures against them.
