Available in PDF, EPUB and Kindle. Book excerpt: A "botnet" is a network of compromised computers (bots) that are controlled by an attacker (botmasters). Botnets are one of the most serious threats to today's Internet; they are the root cause of many current Internet attacks, such as email spam, distributed denial of service (DDoS) attacks, click fraud, etc. There have been many researches on how to detect, monitor, and defend against botnets that have appeared and their attack techniques. However, it is equally important for us to investigate possible attack techniques that could be used by the next generation botnets, and develop effective defense techniques accordingly in order to be well prepared for future botnet attacks. In this dissertation, we focus on two areas of the next generation botnet attacks and defenses: the peer-to-peer (P2P) structured botnets and the possible honeypot detection techniques used by future botnets. Currently, most botnets have centralized command and control (C & C) architecture. However, P2P structured botnets have gradually emerged as a new advanced form of botnets. Without C & C servers, P2P botnets are more resilient to defense countermeasures than traditional centralized botnets. Therefore, we first systematically study P2P botnets along multiple dimensions: bot candidate selection, network construction and C & C mechanisms and communication protocols. As a further illustration of P2P botnets, we then present the design of an advanced hybrid P2P botnet, which could be developed by botmasters in the near future. Compared with current botnets, the proposed botnet is harder to be shut down, monitored, and hijacked. It provides robust network connectivity, individualized encryption and control traffic dispersion, limited botnet exposure by each bot, and easy monitoring and recovery by its botmaster. We suggest and analyze several possible defenses against this advanced botnet. Upon our understanding of P2P botnets, we turn our focus to P2P botnet countermeasures. We provide mathematical analysis of two P2P botnet mitigation approaches--index poisoning defense and Sybil defense, and one monitoring technique--passive monitoring. We are able to give analytical results to evaluate their performance. And simulation-based experiments show that our analysis is accurate. Besides P2P botnets, we investigate honeypot-aware botnets as well. This is because honeypot techniques have been widely used in botnet defense systems, botmasters will have to find ways to detect honeypots in order to protect and secure their botnets. We point out a general honeypot-aware principle, that is security professionals deploying honeypots have liability constraint such that they cannot allow their honeypots to participate in real attacks that could cause damage to others, while attackers do not need to follow this constraint. Based on this principle, a hardware- and software- independent honeypot detection methodology is proposed. We present possible honeypot detection techniques that can be used in both centralized botnets and P2P botnets. Our experiments show that current standard honeypot and honeynet programs are vulnerable to the proposed honeypot detection techniques. In the meantime, we discuss some guidelines for defending against general honeypot-aware botnet attacks.

Book excerpt: The existing state-of-the-art in the field of application layer Distributed Denial of Service (DDoS) protection is generally designed, and thus effective, only for static web domains. To the best of our knowledge, our work is the first that studies the problem of application layer DDoS defense in web domains of dynamic content and organization, and for next-generation bot behaviour. In the first part of this thesis, we focus on the following research tasks: 1) we identify the main weaknesses of the existing application-layer anti-DDoS solutions as proposed in research literature and in the industry, 2) we obtain a comprehensive picture of the current-day as well as the next-generation application-layer attack behaviour and 3) we propose novel techniques, based on a multidisciplinary approach that combines offline machine learning algorithms and statistical analysis, for detection of suspicious web visitors in static web domains. Then, in the second part of the thesis, we propose and evaluate a novel anti-DDoS system that detects a broad range of application-layer DDoS attacks, both in static and dynamic web domains, through the use of advanced techniques of data mining. The key advantage of our system relative to other systems that resort to the use of challenge-response tests (such as CAPTCHAs) in combating malicious bots is that our system minimizes the number of these tests that are presented to valid human visitors while succeeding in preventing most malicious attackers from accessing the web site. The results of the experimental evaluation of the proposed system demonstrate effective detection of current and future variants of application layer DDoS attacks.

The next generation of mobile networks continues to transform the way people communicate and access information. 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 Handbook of Information and Communication Security written by Peter Stavroulakis and published by Springer Science & Business Media. This book was released on 2010-02-23 with total page 863 pages. Available in PDF, EPUB and Kindle. Book excerpt: At its core, information security deals with the secure and accurate transfer of information. While information security has long been important, it was, perhaps, brought more clearly into mainstream focus with the so-called “Y2K” issue. Te Y2K scare was the fear that c- puter networks and the systems that are controlled or operated by sofware would fail with the turn of the millennium, since their clocks could lose synchronization by not recognizing a number (instruction) with three zeros. A positive outcome of this scare was the creation of several Computer Emergency Response Teams (CERTs) around the world that now work - operatively to exchange expertise and information, and to coordinate in case major problems should arise in the modern IT environment. Te terrorist attacks of 11 September 2001 raised security concerns to a new level. Te - ternational community responded on at least two fronts; one front being the transfer of reliable information via secure networks and the other being the collection of information about - tential terrorists. As a sign of this new emphasis on security, since 2001, all major academic publishers have started technical journals focused on security, and every major communi- tions conference (for example, Globecom and ICC) has organized workshops and sessions on security issues. In addition, the IEEE has created a technical committee on Communication and Information Security. Te ?rst editor was intimately involved with security for the Athens Olympic Games of 2004.
Download or read book Next Generation Enterprise Security and Governance written by Mohiuddin Ahmed and published by CRC Press. This book was released on 2022-04-19 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Internet is making our daily lives as digital as possible, and this new era is called the Internet of Everything (IoE). The key force behind the rapid growth of the Internet is the technological advancement of enterprises. The digital world we live in is facilitated by these enterprises’ advances and business intelligence. These enterprises need to deal with gazillions of bytes of data, and in today’s age of General Data Protection Regulation, enterprises are required to ensure privacy and security of large-scale data collections. However, the increased connectivity and devices used to facilitate IoE are continually creating more room for cybercriminals to find vulnerabilities in enterprise systems and flaws in their corporate governance. Ensuring cybersecurity and corporate governance for enterprises should not be an afterthought or present a huge challenge. In recent times, the complex diversity of cyber-attacks has been skyrocketing, and zero-day attacks, such as ransomware, botnet, and telecommunication attacks, are happening more frequently than before. New hacking strategies would easily bypass existing enterprise security and governance platforms using advanced, persistent threats. For example, in 2020, the Toll Group firm was exploited by a new crypto-attack family for violating its data privacy, where an advanced ransomware technique was launched to exploit the corporation and request a huge figure of monetary ransom. Even after applying rational governance hygiene, cybersecurity configuration and software updates are often overlooked when they are most needed to fight cyber-crime and ensure data privacy. Therefore, the threat landscape in the context of enterprises has become wider and far more challenging. There is a clear need for collaborative work throughout the entire value chain of this network. In this context, this book addresses the cybersecurity and cooperate governance challenges associated with enterprises, which will provide a bigger picture of the concepts, intelligent techniques, practices, and open research directions in this area. This book serves as a single source of reference for acquiring the knowledge on the technology, process, and people involved in next-generation privacy and security.

Book excerpt: Emerging alongside the widespread adoption of networked information technologies, cybersecurity incidents represent a significant threat to our common well-being. The institutional construct of a Computer-Emergency Response Team (CERT) began to evolve thirty years ago as a response to security incidents in the nascent Internet. This book, Next Generation CERTs, presents papers arising from the NATO Advanced Research Workshop “New Generation CERT: from Response to Readiness - Strategy and Guidelines”, held in Chiavari, Italy, from 28 - 30 March 2017. The workshop enabled 38 leading experts from NATO members and affiliate states to discuss the limitations of current CERTs and identify the improvements that are likely to shape the CERTs of the future. After the workshop, participants were invited to submit the papers included here. The book is divided into 3 main sections: state of the art; next generation CERTs; and the experience of CERTs. A number of approaches are covered – technical, tactical, strategic – which could be applied to both civilian and military environments. Providing an insight into the likely future development of CERTs, the book will be of interest to all those involved in the field of cybersecurity.
Download or read book Covert Botnet Implementation and Defense Against Covert Botnets written by Lokesh Babu Ramesh Babu and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of the Internet and its benevolent use has benefited mankind in private and business use alike. However, like any other technology, the Internet is often used for malevolent purposes. One such malevolent purpose is to attack computers using botnets. Botnets are stealthy, and the victims are typically unaware of the malicious activities and the resultant havoc they can cause. Computer security experts seek to combat the botnet menace. However, attackers come up with new botnet designs that exploit the weaknesses in existing defense mechanisms and, thus, continue to evade detection. Therefore, it is necessary to analyze the weaknesses of existing defense mechanisms to find the lacunae in them and design new models of bot infection before the attackers do so. It is also necessary to validate the analysis and the design of such a model by implementing the attack and fine-tuning the design. This thesis validates the weaknesses found in existing defense mechanisms against botnets by implementing a new model of botnet and carrying out experiments on it. To merely analyze and present the weaknesses of a defense would open the door for attackers and make their job easier. Thus, creating a defense mechanism against the new attack is equally important. This thesis proposes a design against the new model of bot infection and also implements the design. Experiments were conducted to validate and fine-tune the design and eliminate flaws in the new defense mechanism.
