Heuristic local search algorithms are used to find "good" solutions to the NP-hard combinatorial optimization problems that cannot be solved using analytical methods. Chapter one discusses the characterization and computation of heuristic local search algorithm for the Traveling Salesman Problem (TSP) from the perspective of dynamical systems. The purpose of chapter 2 is to show the practical application of CBIR technology in the security and protection of personal data, access to classified documents and objects, identification of illegal attacks that are part of the social life of the present and future of mankind. Continuous search space problems are difficult problems to solve because the number of solutions is infinite. Moreover, the search space gets more complex as we add constraints to the problem. In this context, chapter 3 aims to show the usage of the differential evolution algorithm for solving continuous search space problems using unconstrained functions and a constrained real-world problem.

A typical Oracle database has multiple users working simultaneously. Data is shared amongst the users, and this of course leads to security concerns. This book comes in from the angle of developing and maintaining a secure Oracle database with multiple users. The book shows how data can be shared in an orderly fashion and what a good secure database is. In this book, we assume that you are acquainted with basic Oracle SQL and fundamentals of relational database.

This book comprehensively covers the principles of Risk-based vulnerability management (RBVM) - one of the most challenging tasks in cybersecurity -- from the foundational mathematical models to building your own decision engine to identify, mitigate, and eventually forecast the vulnerabilities that pose the greatest threat to your organization. You will learn: how to structure data pipelines in security and derive and measure value from them; where to procure open-source data to better your organization's pipeline and how to structure it; how to build a predictive model using vulnerability data; how to measure the return on investment a model in security can yield; which organizational structures and policies work best, and how to use data science to detect when they are not working in security; and ways to manage organizational change around data science implementation. You'll also be shown real-world examples of how to mature an RBVM program and will understand how to prioritize remediation efforts based on which vulnerabilities pose the greatest risk to your organization. The book presents a fresh approach, rooted in risk management, and taking advantage of rich data and machine learning, helping you focus more on what matters and ultimately make your organization more secure with a system commensurate to the scale of the threat. This is a timely and much-needed book for security managers and practitioners who need to evaluate their organizations and plan future projects and change. Students of cybersecurity will also find this a valuable introduction on how to use their skills in the enterprise workplace to drive change.

Private entities, especially those critical to our nation's infrastructure, are responsible for assessing their individual risk and investing in technology to prevent breaches. At the same time, the federal government must develop a comprehensive approach to not only defend against cyberattacks, but also to punish foreign adversaries who continue to perpetrate them. This book examines policies that will help secure our critical infrastructure networks.

The global Internet and cyberspace age witness a new generation of cybercriminals, hackers, cybergangs, cyber terrorists, and cyber sexual harassers. This phenomenon, broadly defined as cybercrimes, is the focus of this book. The International Telecommunication Union's Global Cyber Security Index found that about 90 percent of the world's countries have enacted laws and regulations to control and combat cybercrime. This book has examined some of those cyber laws and regulations in 12 countries, including the United States, United Kingdom, Canada, China, Russia, Japan, Singapore, Nigeria, South Africa, India, Pakistan, and Bangladesh. Different chapters of this book have found some common themes. First, in most of the countries of the world, there is an advancing process of legally criminalizing cybercrimes, including such behaviors as unauthorized access, use, and interception; damage and deletion of computer data; damage and destruction of computer networks; and dissemination and transportation of illegally obtained computer data. Second, there is high sensitivity in all countries studied about the security of the information infrastructure and their critical economic, political, and social infrastructures such as power plants, chemical industries, aviation systems, and electoral systems. Third, all forms of cybercrime committed by using the computer and the Internet are also defined as fraud and forgery, identity theft, cyber espionage, sexual harassment, cyber sexual extortion, online child pornography, and revenge pornography. One of the more critical themes that emerged is that no country defines cybersecurity as just a technical matter-a matter only of coding and decoding and encryption and decryption. Cybersecurity is also broadly perceived as a legal, political, organizational, and educational issue. It is perceived as a matter to be dealt with by a government in cooperation with international partners, potentially barring China and Russia. One of the other themes that emerged as a genuine concern is the rapid escalation of cyber sexual violence against women and minors. In most countries examined in this book, the policymakers and law enforcement believe that social media is partly responsible for increasing cyber sexual violence.

Machine learning is a subfield of artificial intelligence, broadly defined as a machine's capability to imitate intelligent human behavior. Like humans, machines become capable of making intelligent decisions by learning from their past experiences. Machine learning is being employed in many applications, including fraud detection and prevention, self-driving cars, recommendation systems, facial recognition technology, and intelligent computing. This book helps beginners learn the art and science of machine learning. It presens real-world examples that leverage the popular Python machine learning ecosystem,

The genius and artistry behind Superbrothers and the making of an indie video game, from inception to its highly anticipated launch. Superbrothers: Sword & Sworcery was released in 2011 at the forefront of an exciting era of "indie games" - with the aesthetic of punk rock and the edge of modernist fiction, indie games pushed gaming into the realm of the avant-garde. Superbrothers (Craig D. Adams) was hailed as a visionary in the video game world. Now, his long-awaited follow-up, JETT: The Far Shore, has been released for Sony PlayStation and Epic Games Store. In the decade from inception to launch, Adams brought author Adam Hammond along for the ride, allowing unprecedented insight into the complicated genesis of Jett. The Far Shore offers a portrait of the enigmatic Adams and his team, the genius and artistry, the successes and setbacks, that went into building the world of JETT, in which you're tasked with scouting a new home for a humanoid people after they've decimated their planet. To provide context, Hammond recounts the history of indie games and how their trajectory has followed that of independent art and literature. A riveting insider's look at one of our most popular art forms.

For centuries, thinkers of all stripes have said that life is a game. What if that is true? What if life really is a game? What if our presence here is part of a vast and beautiful interactive machine? Edward Castronova urges readers to think about the human condition in the same way that a player thinks about a game. So many of the mechanics we see in games are present in daily life, from role-playing and levelling up, to investing, diplomacy, and the sublime tension between the risk of loss and the thrill of victory. What is 'victory,' though? We all have our own ideas about how to win this game. Some say the point is to feel good. Others say it is all about God, with Heaven as the win condition. However we envision our lives, game designs tells us how best to play. We decide what it means to win this game; game thinking tells us the most sensible way to do it. Thus, though it is new, the field of game design has much to say about the fundamental questions of human existence. Philosophy asks why we are here. Game Design answers: To interact, to choose, to play.
