Practical software security metrics and measurements are essential to the development of secure software [18]. In this paper, we propose to use a software system's attack surface measurement as an indicator of the system's security; the larger the attack surface, the more insecure the system. We formalize the notion of a system's attack surface using an I/O automata model of the system [15] and define a quantitative measure of the attack surface in terms of three kinds of resources used in attacks on the system: methods, channels, and data. We demonstrate the feasibility of our approach by measuring the attack surfaces of two open source FTP daemons and two IMAP servers. Software developers can use our attack surface measurement method in the software development process and software consumers can use the method in their decision making process....

Moving Target Defense: Creating Asymmetric Uncertainty for Cyber Threats was developed by a group of leading researchers. It describes the fundamental challenges facing the research community and identifies new promising solution paths. Moving Target Defense which is motivated by the asymmetric costs borne by cyber defenders takes an advantage afforded to attackers and reverses it to advantage defenders. Moving Target Defense is enabled by technical trends in recent years, including virtualization and workload migration on commodity systems, widespread and redundant network connectivity, instruction set and address space layout randomization, just-in-time compilers, among other techniques. However, many challenging research problems remain to be solved, such as the security of virtualization infrastructures, secure and resilient techniques to move systems within a virtualized environment, automatic diversification techniques, automated ways to dynamically change and manage the configurations of systems and networks, quantification of security improvement, potential degradation and more. Moving Target Defense: Creating Asymmetric Uncertainty for Cyber Threats is designed for advanced -level students and researchers focused on computer science, and as a secondary text book or reference. Professionals working in this field will also find this book valuable....

Our cyber defenses are static and are governed by lengthy processes, e.g., for testing and security patch deployment. Adversaries could plan their attacks carefully over time and launch attacks at cyber speeds at any given moment. We need a new class of defensive strategies that would force adversaries to continually engage in reconnaissance and re-planning of their cyber operations. One such strategy is to present adversaries with a moving target where the attack surface of a system keeps changing. Moving Target Defense II: Application of Game Theory and Adversarial Modeling includes contributions from world experts in the cyber security field. In the first volume of MTD, we presented MTD approaches based on software transformations, and MTD approaches based on network and software stack configurations. In this second volume of MTD, a group of leading researchers describe game theoretic, cyber maneuver, and software transformation approaches for constructing and analyzing MTD systems. Designed as a professional book for practitioners and researchers working in the cyber security field, advanced -level students and researchers focused on computer science will also find this book valuable as a secondary text book or reference....

The ground segment is the fundamental backbone of every satellite project, yet it is usually not visible to the public or the end user of a satellite service. Also the bulk of existing published space literature tends to focus on the satellite or its subsystems. This book tries to fill this gap and addresses systems engineering concepts applied to the design, development, qualification, and deployment of the ground control segment required to operate a single satellite, a constellation, or even a manned space vehicle. The domain of ground segment engineering has significantly evolved in recent years, mainly driven by major advances in the IT sector. Hardware virtualisation or the availability of on-demand cloud computing services are typical examples of new technologies that have changed fundamental architectural concepts previously standard in heritage ground segments. Furthermore, the stark increase of cyber attacks - today a major risk to almost all critical IT based infrastructure - has made a cyber threat resilient architecture to become one of the indispensable design requirements for ground segment engineers. The new mega constellations recently put into space deploying up to several hundred of flying objects have put very demanding needs on the ground segment for automated satellite operations. These topics and more are addressed in the book’s chapters, along with a detailed explanation of the most relevant components of a typical ground segment architecture. The basic functional requirements, design features, and the most important ground and space segment interfaces are addressed and explained in detail, supported by a wealth of figures for easier understanding. This book is kept at an introductory level, allowing newcomers to get familiar with this fairly complex subject matter. It is therefore suitable for graduate students, but can equally serve as a valuable source of information for already experienced space engineers who seek to gain a deeper understanding of the ground segment infrastructure and related systems engineering processes. It can also help project managers to better interact with their systems engineers, satellite developers to define their ground segment interfaces, and satellite operators to improve their flight and ground procedures. It is very well suited for everyone intending to start a career in satellite ground segment systems engineering....

Learn the Root Causes of Software Vulnerabilities and How to Avoid Them Commonly exploited software vulnerabilities are usually caused by avoidable software defects. Having analyzed tens of thousands of vulnerability reports since 1988, CERT has determined that a relatively small number of root causes account for most of the vulnerabilities. Secure Coding in C and C++, Second Edition, identifies and explains these root causes and shows the steps that can be taken to prevent exploitation. Moreover, this book encourages programmers to adopt security best practices and to develop a security mindset that can help protect software from tomorrow’s attacks, not just today’s. Drawing on the CERT’s reports and conclusions, Robert C. Seacord systematically identifies the program errors most likely to lead to security breaches, shows how they can be exploited, reviews the potential consequences, and presents secure alternatives. Coverage includes technical detail on how to Improve the overall security of any C or C++ application Thwart buffer overflows, stack-smashing, and return-oriented programming attacks that exploit insecure string manipulation logic Avoid vulnerabilities and security flaws resulting from the incorrect use of dynamic memory management functions Eliminate integer-related problems resulting from signed integer overflows, unsigned integer wrapping, and truncation errors Perform secure I/O, avoiding file system vulnerabilities Correctly use formatted output functions without introducing format-string vulnerabilities Avoid race conditions and other exploitable vulnerabilities while developing concurrent code The second edition features Updates for C11 and C++11 Significant revisions to chapters on strings, dynamic memory management, and integer security A new chapter on concurrency Access to the online secure coding course offered through Carnegie Mellon’s Open Learning Initiative (OLI) Secure Coding in C and C++, Second Edition, presents hundreds of examples of secure code, insecure code, and exploits, implemented for Windows and Linux. If you’re responsible for creating secure C or C++ software–or for keeping it safe–no other book offers you this much detailed, expert assistance....
