Available in PDF, EPUB and Kindle. Book excerpt: Unwelcome intrusions into computer systems are being perpetrated by strangers, and the number of such incidents is rising steadily. One of the things that facilitates this malfeasance is that computer networks provide the ability for a user to log into multiple computer systems in sequence, changing identity with each step. This makes it very difficult to trace actions on a network of computers all the way back to their actual origins. We refer to this as the tracing problem. This thesis attempts to address this problem by the development of a technology called thumbprinting. Thumbprinting involves forming a signature of the data in a network connection. This signature is a small quantity which does not allow complete reconstruction of the data, but does allow comparison with signatures of other connections to determine with reasonable confidence whether the data were the same or not. This is a potential basis for a tracing system. The specific technology developed to perform this task is local thumbprinting. This involves forming linear combinations of the frequencies with which different characters occur in the network data sampled. The optimal linear combinations are chosen using a statistical methodology called principal component analysis. The difficulties which this process must overcome are outlined, and an algorithm for comparing the thumbprints which adaptively handles these difficulties is presented. A number of experiments with a trial implementation of this method are described. The method is shown to work successfully when given at least a minute and a half of reasonably active network connection. This requires presently about 20 bytes per minute per connection of storage for the thumbprints. In addition, the existing (very limited) literature on the tracing problem is reviewed.

Book excerpt: Network based intruders seldom attack directly from their own hosts but rather stage their attacks through intermediate 'stepping stones' to conceal their identity and origin. To track down and apprehend those perpetrators behind stepping stones, it is critically important to be able to correlate connections through stepping stones. Tracing intruders behind stepping stones and correlating intrusion connections through stepping stones are challenging due to various readily available evasive countermeasures by intruders: " nstalling and using backdoor relays (i.e. netcat) at intermediate stepping stones to evade logging of normal logins." sing different types of connections (i.e. TCP, UDP) at different portions of the connection chain through stepping stones to complicate connection matching." sing encrypted connections (with different keys) across stepping stones to defeat any content based comparison." Introducing timing perturbation at intermediate stepping stones to counteract timing based correlation of encrypted connections. In this dissertation, we address these challenges in detail and design solutions to them. For unencrypted intrusion connections through stepping stones, we design and implement a novel intrusion tracing framework called Sleepy Watermark Tracing (SWT), which applies principles of steganography and active networking. SWT is "sleepy" in that it does not introduce overhead when no intrusion is detected. Yet it is "active" in that when an intrusion is detected, the host under attack will inject a watermark into the backward connection of the intrusion, and wake up and collaborate with intermediate routers along the intrusion path. Our prototype shows that SWT can trace back to the trustworthy security gateway closest to the origin of the intrusion, with only a single packet from the intruder. With its unique active tracing, SWT can even trace when intrusion connections are idle. Encryption of connections through steppin.

Book excerpt: As distinct from other security and cryptography conferences, the Information Security Conference (ISC) 2002 brought together individuals involved in a wide variety of different disciplines of information security to foster the exchange of ideas. The conference is an outgrowth of the Information Security Workshop, first held in Ishikawa, Japan 1997. ISC 2002 was held in Sao Paulo, Brazil, on September 30– October 2, 2002. The Program Committee considered 81 submissions of which 38 papers were accepted for presentation. These proceedings contain revised versions of the accepted papers. The papers provide a representative sample of both the variety and the truly international scope of information security research conducted currently. The topics addressed range from e-commerce protocols to access control and trust management, and to cryptography and cryptographic algorithms. Many people deserve our gratitude for their contribution to the success of the conference. We would like to thank the General Chair, Routo Terada, for overseeing the local arrangements, including registration and maintaining the conference website, and for the smooth running of the conference. We are grateful to Robbie Ye for his expert help in processing the electronic submissions, reviews and acceptance notifications. Robbie’s enthusiasm and energy greatly simplified the Program Committee’s task of conducting the on-line evaluation of the submitted papers under tight time constraints.

Book excerpt: Since the early eighties IFIP/Sec has been an important rendezvous for Information Technology researchers and specialists involved in all aspects of IT security. The explosive growth of the Web is now faced with the formidable challenge of providing trusted information. IFIP/Sec’01 is the first of this decade (and century) and it will be devoted to “Trusted Information - the New Decade Challenge” This proceedings are divided in eleven parts related to the conference program. Session are dedicated to technologies: Security Protocols, Smart Card, Network Security and Intrusion Detection, Trusted Platforms. Others sessions are devoted to application like eSociety, TTP Management and PKI, Secure Workflow Environment, Secure Group Communications, and on the deployment of applications: Risk Management, Security Policies andTrusted System Design and Management. The year 2001 is a double anniversary. First, fifteen years ago, the first IFIP/Sec was held in France (IFIP/Sec’86, Monte-Carlo) and 2001 is also the anniversary of smart card technology. Smart cards emerged some twenty years ago as an innovation and have now become pervasive information devices used for highly distributed secure applications. These cards let millions of people carry a highly secure device that can represent them on a variety of networks. To conclude, we hope that the rich “menu” of conference papers for this IFIP/Sec conference will provide valuable insights and encourage specialists to pursue their work in trusted information.

We are currently witnessing a proliferation in mobile/wireless technologies and applications. However, these new technologies have ushered in unprecedented challenges for the research community across the range of networking, mobile computing, network security and wireless web applications, and optical network topics. ICCNMC 2005 was sponsored by the China Computer Federation, in cooperation with the Institute for Electrical and Electronics Engineers (IEEE) Computer Society. The objective of this conference was to address and capture highly innovative and stateof-the-art research and work in the networks and mobile computing industries. ICCNMC 2005 allowed sharing of the underlying theories and applications, and the establishment of new and long-term collaborative channels aimed at developing innovative concepts and solutions geared to future markets. The highly positive response to ICCNMC 2001 and ICCNMC 2003, held in Beijing and Shanghai, respectively, encouraged us to continue this international event. In its third year, ICCNMC 2005 continued to provide a forum for researchers, professionals, and industrial practitioners from around the world to report on new advances in computer network and mobile computing, as well as to identify issues and directions for research and development in the new era of evolving technologies.

Download or read book Mobile Hybrid Intrusion Detection written by Álvaro Herrero and published by Springer Science & Business Media. This book was released on 2011-01-19 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph comprises work on network-based Intrusion Detection (ID) that is grounded in visualisation and hybrid Artificial Intelligence (AI). It has led to the design of MOVICAB-IDS (MObile VIsualisation Connectionist Agent-Based IDS), a novel Intrusion Detection System (IDS), which is comprehensively described in this book. This novel IDS combines different AI paradigms to visualise network traffic for ID at packet level. It is based on a dynamic Multiagent System (MAS), which integrates an unsupervised neural projection model and the Case-Based Reasoning (CBR) paradigm through the use of deliberative agents that are capable of learning and evolving with the environment. The proposed novel hybrid IDS provides security personnel with a synthetic, intuitive snapshot of network traffic and protocol interactions. This visualisation interface supports the straightforward detection of anomalous situations and their subsequent identification. The performance of MOVICAB-IDS was tested through a novel mutation-based testing method in different real domains which entailed several attacks and anomalous situations.
