This book presents the most interesting talks given at ISSE 2006 - the forum for the interdisciplinary discussion of how to adequately secure electronic business processes. The topics include: Smart Token and e-ID-Card Developments and their Application - Secure Computing and how it will change the way we trust computers - Risk Management and how to quantify security threats - Awareness raising, Data Protection and how we secure corporate information.Adequate information security is one of the basic requirements of all electronic business processes. It is crucial for effective solutions that the possibilities offered by security technology can be integrated with the commercial requirements of the applications. The reader may expect state-of-the-art: best papers of the Conference ISSE 2006.

Since 1998, RAID has established its reputation as the main event in research on intrusion detection, both in Europe and the United States. Every year, RAID gathers researchers, security vendors and security practitioners to listen to the most recent research results in the area as well as experiments and deployment issues. This year, RAID has grown one step further to establish itself as a well-known event in the security community, with the publication of hardcopy proceedings. RAID 2000 received 26 paper submissions from 10 countries and 3 continents. The program committee selected 14 papers for publication and examined 6 of them for presentation. In addition RAID 2000 received 30 extended abstracts proposals; 15 of these extended abstracts were accepted for presentation. - tended abstracts are available on the website of the RAID symposium series, http://www.raid-symposium.org/. We would like to thank the technical p- gram committee for the help we received in reviewing the papers, as well as all the authors for their participation and submissions, even for those rejected. As in previous RAID symposiums, the program alternates between fun- mental research issues, such as newtechnologies for intrusion detection, and more practical issues linked to the deployment and operation of intrusion det- tion systems in a real environment. Five sessions have been devoted to intrusion detection technology, including modeling, data mining and advanced techniques.

Digitalisierung und Informationssicherheit gehören untrennbar zusammenInformationssicherheit und Digitalisierung sind zwei Seiten derselben Medaille. Das BSI steht für beides und ist als die Cyber-Sicherheitsbehörde des Bundes Gestalter einer sicheren Digitalisierung. Wie die Spinne im Netz der Cyber-Sicherheit ist es vielfach vernetzt - nach innen und nach außen. Teil dieses vernetzten Denkens ist auch der Deutsche IT-Sicherheitskongress, den das BSI am 2. und 3. Februar 2021 zum 17. Mal ausgerichtet hat. Das Programm des in diesem Jahr virtuell stattfindenden Kongresses umfasste rund 30 Fachvorträge zu Themen wie Social Engineering, Notfallangebote für KMU, Hochsichere Cloud, Cyber Resilience, Post-Quanten-Kryptografie, Umgang mit Datenschutzkatastrophen, Awareness Trainings und Identitätsdiebstahl. Im Jubiläumsjahr des BSI bot der IT-Sicherheitskongress unter dem Motto "Deutschland. Digital. Sicher. 30 Jahre BSI" gleichzeitig eine Möglichkeit, auf 30 Jahre Informationssicherheit in Deutschland zurückzublicken.

Mit seiner Tagung 2020 zum Thema "Kommunikationssicherheit im IoT" greift der GI/GMA/ITG-Fachausschuss Echtzeitsysteme ein immer wichtiger werdendes Thema in einer mehr und mehr vernetzten Welt auf.

This SpringerBrief explores graphical password systems and examines novel drawing-based methods in terms of security, usability, and human computer-interactions. It provides a systematic approach for recognizing, comparing, and matching sketch-based passwords in the context of modern computing systems. The book offers both a security and usability analysis of the accumulative framework used for incorporating handwriting biometrics and a human computer-interaction performance analysis. The chapters offer new perspectives and experimental results regarding model uniqueness, recognition tolerance, and the human-computer interaction. The results demonstrate that biometrics reduce the equal error rate (EER) by more than 10%, and show that people are capable of accurately reproducing a sketch-based password. Fundamentals of Sketch-based Passwords: A General Framework targets computer scientists and engineers focused on computer security, biometrics, and human factors. Advanced-level students in computer science and electrical engineering will find this material useful as a study guide for their classes.

This book is the first publication to give a comprehensive, structured treatment to the important topic of situational awareness in cyber defense. It presents the subject in a logical, consistent, continuous discourse, covering key topics such as formation of cyber situational awareness, visualization and human factors, automated learning and inference, use of ontologies and metrics, predicting and assessing impact of cyber attacks, and achieving resilience of cyber and physical mission. Chapters include case studies, recent research results and practical insights described specifically for this book. Situational awareness is exceptionally prominent in the field of cyber defense. It involves science, technology and practice of perception, comprehension and projection of events and entities in cyber space. Chapters discuss the difficulties of achieving cyber situational awareness ¿ along with approaches to overcoming the difficulties - in the relatively young field of cyber defense where key phenomena are so unlike the more conventional physical world. Cyber Defense and Situational Awareness is designed as a reference for practitioners of cyber security and developers of technology solutions for cyber defenders. Advanced-level students and researchers focused on security of computer networks will also find this book a valuable resource.

Platform Embedded Security Technology Revealed is an in-depth introduction to Intel’s platform embedded solution: the security and management engine. The engine is shipped inside most Intel platforms for servers, personal computers, tablets, and smartphones. The engine realizes advanced security and management functionalities and protects applications’ secrets and users’ privacy in a secure, light-weight, and inexpensive way. Besides native built-in features, it allows third-party software vendors to develop applications that take advantage of the security infrastructures offered by the engine. Intel’s security and management engine is technologically unique and significant, but is largely unknown to many members of the tech communities who could potentially benefit from it. Platform Embedded Security Technology Revealed reveals technical details of the engine. The engine provides a new way for the computer security industry to resolve critical problems resulting from booming mobile technologies, such as increasing threats against confidentiality and privacy. This book describes how this advanced level of protection is made possible by the engine, how it can improve users’ security experience, and how third-party vendors can make use of it. It's written for computer security professionals and researchers; embedded system engineers; and software engineers and vendors who are interested in developing new security applications on top of Intel’s security and management engine.It’s also written for advanced users who are interested in understanding how the security features of Intel’s platforms work.

This Festschrift volume, published in honor of Brian Randell on the occasion of his 75th birthday, contains a total of 37 refereed contributions. Two biographical papers are followed by the six invited papers that were presented at the conference 'Dependable and Historic Computing: The Randell Tales', held during April 7-8, 2011 at Newcastle University, UK. The remaining contributions are authored by former scientific colleagues of Brian Randell.The papers focus on the core of Brian Randell's work: the development of computing science and the study of its history. Moreover, his wider interests are reflected and so the collection comprises papers on software engineering, storage fragmentation, computer architecture, programming languages and dependability. There is even a paper that echoes Randell's love of maps.After an early career with English Electric and then with IBM in New York and California, Brian Randell joined Newcastle University. His main research has been on dependable computing in all its forms, especially reliability, safety and security aspects, and he has led several major European collaborative projects.
