This book presents a comprehensive overview of security issues in Cyber Physical Systems (CPSs), by analyzing the issues and vulnerabilities in CPSs and examining state of the art security measures. Furthermore, this book proposes various defense strategies including intelligent attack and anomaly detection algorithms. Today's technology is continually evolving towards interconnectivity among devices. This interconnectivity phenomenon is often referred to as Internet of Things (IoT). IoT technology is used to enhance the performance of systems in many applications. This integration of physical and cyber components within a system is associated with many benefits; these systems are often referred to as Cyber Physical Systems (CPSs). The CPSs and IoT technologies are used in many industries critical to our daily lives. CPSs have the potential to reduce costs, enhance mobility and independence of patients, and reach the body using minimally invasive techniques. Although this interconnectivity of devices can pave the road for immense advancement in technology and automation, the integration of network components into any system increases its vulnerability to cyber threats. Using internet networks to connect devices together creates access points for adversaries. Considering the critical applications of some of these devices, adversaries have the potential of exploiting sensitive data and interrupting the functionality of critical infrastructure. Practitioners working in system security, cyber security & security and privacy will find this book valuable as a reference. Researchers and scientists concentrating on computer systems, large-scale complex systems, and artificial intelligence will also find this book useful as a reference.

Earth at Risk in the 21st Century offers critical interdisciplinary reflections on peace, security, gender relations, migration and the environment, all of which are threatened by climate change, with women and children affected most. Deep-rooted gender discrimination is also a result of the destructive exploitation of natural resources and the pollution of soils, water, biota and air. In the Anthropocene, the management of human society and global resources has become unsustainable and has created multiple conflicts by increasing survival threats primarily for poor people in the Global South. Alternative approaches to peace and security, focusing from bottom-up on an engendered peace with sustainability, may help society and the environment to be managed in the highly fragile natural conditions of a 'hothouse Earth'. Thus, the book explores systemic alternatives based on indigenous wisdom, gift economy and the economy of solidarity, in which an alternative cosmovision fosters mutual care between humankind and nature. * Special analysis of risks to the survival of humankind in the 21st century. * Interdisciplinary studies on peace, security, gender and environment related to global environmental and climate change. * Critical reflections on gender relations, peace, security, migration and the environment * Systematic analysis of food, water, health, energy security and its nexus. * Alternative proposals from the Global South with indigenous wisdom for saving Mother Earth.

There are three fundamental components in Control-Flow Integrity (CFI) enforcement. The first component is accurately recovering the policy (CFG). Usually, the more precise the policy is, the more security CFI improves, but precise CFG generation was considered hard without the support of source code. The second component is embedding the CFI policy securely. Current CFI enforcement usually inserts checks before indirect branches to consult a read-only table which stores the valid CFG information. However, this kind of read-only table can be overwritten by some kinds of attacks (e.g., the Rowhammer attack and data-oriented programming). The third component is to efficiently enforce the CFI policy. In current approaches CFI checks are always executed whenever there is an indirect control flow transfer. Therefore, it is critical to minimize the performance impact of CFI checks. In this book, we propose novel solutions to handle these three fundamental components. To generate a precise CFI policy without the support of the source code, we systematically study two methods which recover CFI policy based on function signature matching at the binary level and propose our novel rule- and heuristic-based mechanism to more accurately recover function signature. To embed CFI policy securely, we design a novel platform which encodes the policy into the machine instructions directly without relying on consulting any read-only data structure, by making use of the idea of instruction-set randomization. Each basic block is encrypted with a key derived from the CFG. To efficiently enforce CFI policy, we make use of a mature dynamic code optimization platform called DynamoRIO to enforce the policy so that we are only required to do the CFI check when needed.

"A much-needed service for society today. I hope this book reaches information managers in the organization now vulnerable to hacks that are stealing corporate information and even holding it hostage for ransom." - Ronald W. Hull, author, poet, and former professor and university administrator A comprehensive entity security program deploys information asset protection through stratified technological and non-technological controls. Controls are necessary for counteracting threats, opportunities, and vulnerabilities risks in a manner that reduces potential adverse effects to defined, acceptable levels. This book presents a methodological approach in the context of normative decision theory constructs and concepts with appropriate reference to standards and the respective guidelines. Normative decision theory attempts to establish a rational framework for choosing between alternative courses of action when the outcomes resulting from the selection are uncertain. Through the methodological application, decision theory techniques can provide objectives determination, interaction assessments, performance estimates, and organizational analysis. A normative model prescribes what should exist according to an assumption or rule.
