This book constitutes the thoroughly refereed post-proceedings of the Second Mext-NSF-JSPS Interntional Symposium on Software Security, ISSS 2003, held in Tokyo, Japan in November 2003. The 18 revised full invited and selected papers presented were carefully reviewed and improved for inclusion in the book. The papers are organized in topical sections on analysis of protocols and cryptography, verification of security properties, safe implementation of programming languages, secure execution environments, and secure systems and security management.

For more than the last three decades, the security of software systems has been an important area of computer science, yet it is a rather recent general recognition that technologies for software security are highly needed. This book assesses the state of the art in software and systems security by presenting a carefully arranged selection of revised invited and reviewed papers. It covers basic aspects and recently developed topics such as security of pervasive computing, peer-to-peer systems and autonomous distributed agents, secure software circulation, compilers for fail-safe C language, construction of secure mail systems, type systems and multiset rewriting systems for security protocols, and privacy issues as well.

In today’s globalized world, businesses and governments rely heavily on technology for storing and protecting essential information and data. Despite the benefits that computing systems offer, there remains an assortment of issues and challenges in maintaining the integrity and confidentiality of these databases. As professionals become more dependent cyberspace, there is a need for research on modern strategies and concepts for improving the security and safety of these technologies. Modern Theories and Practices for Cyber Ethics and Security Compliance is a collection of innovative research on the concepts, models, issues, challenges, innovations, and mitigation strategies needed to improve cyber protection. While highlighting topics including database governance, cryptography, and intrusion detection, this book provides guidelines for the protection, safety, and security of business data and national infrastructure from cyber-attacks. It is ideally designed for security analysts, law enforcement, researchers, legal practitioners, policymakers, business professionals, governments, strategists, educators, and students seeking current research on combative solutions for cyber threats and attacks.

Following the success of the International Symposium on Software Security 2002 (ISSS 2002), held in Keio University, Tokyo, November, 2002, ISSS 2003 was held in the Tokyo Institute of Technology, Tokyo, on November 4-6, 2003. This volume is the collection of the papers that were presented at ISSS 2003. The proceedings of ISSS 2002 was published as LNCS 2609. Although the security and reliability of software systems for networked c- puter systems are major concerns of current society, the technology for software securitystillneedstobedevelopedinmanydirections.SimilartoISSS2002,ISSS 2003 aimed to provide a forum for research discussions and exchanges among world-leading scientists in the ?elds of both theoretical and systems aspects of security in software construction. The program of ISSS 2003 was a combination of invited talks and selected research contributions. It included the most recent visions and researches of the 9invitedspeakers,aswellas11contributionsofresearchesfundedbytheMEXT grant-in-aid for scienti?c research on the priority area "Implementation Scheme for Secure Computing" (AnZenKaken). We collected the original contributions after their presentation at the symposium and began a review procedure that resulted in the selection of the papers in this volume. They appear here in ?nal form. ISSS 2003 required a lot of work that was heavily dependent on members of the program committee, and sta?s and graduate students who participated in AnZenKaken. We sincerely thank them for their e?orts and time.
