Such issues discussed include formal methods and models, software testing, safety critical systems, reliability and safety assessment, total quality management, human factors for safety, management, social and legal aspects, and security-critical systems. In addition, the book includes a number of papers on issues with a given practical value. These papers have emerged from applications in several different domains.

It is, indeed, widely acceptable today that nowhere is it more important to focus on the improvement of software quality than in the case of systems with requirements in the areas of safety and reliability - especially for distributed, real-time and embedded systems. Thus, much research work is under progress in these fields, since software process improvement impinges directly on achieved levels of quality, and many application experiments aim to show quantitative results demonstrating the efficacy of particular approaches. Requirements for safety and reliability - like other so-called non-functional requirements for computer-based systems - are often stated in imprecise and ambiguous terms, or not at all. Specifications focus on functional and technical aspects, with issues like safety covered only implicitly, or not addressed directly because they are felt to be obvious; unfortunately what is obvious to an end user or system user is progressively less so to others, to the extend that a software developer may not even be aware that safety is an issue. Therefore, there is a growing evidence for encouraging greater understanding of safety and reliability requirements issues, right across the spectrum from end user to software developer; not just in traditional safety-critical areas (e.g. nuclear, aerospace) but also acknowledging the need for such things as heart pacemakers and other medical and robotic systems to be highly dependable.

This book presents the latest trends in attacks and protection methods of Critical Infrastructures. It describes original research models and applied solutions for protecting major emerging threats in Critical Infrastructures and their underlying networks. It presents a number of emerging endeavors, from newly adopted technical expertise in industrial security to efficient modeling and implementation of attacks and relevant security measures in industrial control systems; including advancements in hardware and services security, interdependency networks, risk analysis, and control systems security along with their underlying protocols.Novel attacks against Critical Infrastructures (CI) demand novel security solutions. Simply adding more of what is done already (e.g. more thorough risk assessments, more expensive Intrusion Prevention/Detection Systems, more efficient firewalls, etc.) is simply not enough against threats and attacks that seem to have evolved beyond modern analyses and protection methods.The knowledge presented here will help Critical Infrastructure authorities, security officers, Industrial Control Systems (ICS) personnel and relevant researchers to (i) get acquainted with advancements in the field, (ii) integrate security research into their industrial or research work, (iii) evolve current practices in modeling and analyzing Critical Infrastructures, and (iv) moderate potential crises and emergencies influencing or emerging from Critical Infrastructures.

This book provides a holistic overview of current state of the art and practice in malware research as well as the challenges of malware research from multiple angles. It also provides step-by-step guides in various practical problems, such as unpacking real-world malware and dissecting it to collect and perform a forensic analysis. Similarly, it includes a guide on how to apply state-of-the-art Machine Learning methods to classify malware. Acknowledging that the latter is a serious trend in malware, one part of the book is devoted to providing the reader with the state-of-the-art in Machine Learning methods in malware classification, highlighting the different approaches that are used for, e.g., mobile malware samples and introducing the reader to the challenges that are faced when shifting from a lab to production environment.Modern malware is fueling a worldwide underground economy. The research for this book is backed by theoretical models that simulate how malware propagates and how the spread could be mitigated. The necessary mathematical foundations and probabilistic theoretical models are introduced, and practical results are demonstrated to showcase the efficacy of such models in detecting and countering malware. It presents an outline of the methods that malware authors use to evade detection. This book also provides a thorough overview of the ecosystem, its dynamics and the geopolitical implications are introduced. The latter are complemented by a legal perspective from the African legislative efforts, to allow the reader to understand the human and social impact of malware.This book is designed mainly for researchers and advanced-level computer science students trying to understand the current landscape in malware, as well as applying artificial intelligence and machine learning in malware detection and classification. Professionals who are searching for a perspective to streamline the challenges that arise, when bringing lab solutions into a production environment, and how to timely identify ransomware signals at scale will also want to purchase this book. Beyond data protection experts, who would like to understand how malware siphons private information, experts from law enforcement authorities and the judiciary system, who want to keep up with the recent developments will find this book valuable as well.

This book constitutes the refereed proceedings of the 13th International Conference on Cryptology and Network Security, CANS 2014, held in Heraklion, Creete, Greece, in October 2014. The 25 revised full papers presented together with the abstracts of 3 invited talks were carefully reviewed and selected from 86 submissions.

It was an honor and a privilege to chair the 24th IFIP International Information Se- rity Conference (SEC 2009), a 24-year-old event that has become a tradition for - formation security professionals around the world. SEC 2009 was organized by the Technical Committee 11 (TC-11) of IFIP, and took place in Pafos, Cyprus, during May 18–20, 2009. It is an indication of good fortune for a Chair to serve a conference that takes place in a country with the natural beauty of Cyprus, an island where the hospitality and frie- liness of the people have been going together, hand-in-hand, with its long history. This volume contains the papers selected for presentation at SEC 2009. In response to the call for papers, 176 papers were submitted to the conference. All of them were evaluated on the basis of their novelty and technical quality, and reviewed by at least two members of the conference Program Committee. Of the papers submitted, 39 were selected for presentation at the conference; the acceptance rate was as low as 22%, thus making the conference a highly competitive forum. It is the commitment of several people that makes international conferences pos- ble. That also holds true for SEC 2009. The list of people who volunteered their time and energy to help is really long.

The EuropeanSymposium on Researchin Computer Security (ESORICS) has a tradition that goes back two decades. It tries to bring together the international research community in a top-quality event that covers all the areas of computer security, ranging from theory to applications. ESORICS 2010 was the 15th edition of the event. It was held in Athens, Greece, September 20-22, 2010. The conference received 201 submissions. The papers went through a careful review process. In a ?rst round, each paper - ceived three independent reviews. For the majority of the papers an electronic discussion was also organized to arrive at the ?nal decision. As a result of the review process, 42 papers were selected for the ?nal program, resulting in an - ceptance rate of as low as 21%. The authors of accepted papers were requested to revise their papers, based on the comments received. The program was c- pleted with an invited talk by Udo Helmbrecht, Executive Director of ENISA (European Network and Information Security Agency). ESORICS 2010 was organized under the aegisof three Ministries of the G- ernment of Greece, namely: (a) the Ministry of Infrastructure, Transport, and Networks, (b) the General Secretariat for Information Systems of the Ministry of Economy and Finance, and (c) the General Secretariat for e-Governance of the Ministry of Interior, Decentralization, and e-Government.
