A collection of articles on the topic of computer and computer network security, ranging from the technical details and history of intruders, worms, and viruses, to the sociopolitical, ethical, and legal implications of computer attacks.

The wording "Under Attack" implies a dangerous situation - one that signifies we are currently under assault. In this book, the Celebrity Experts(r) showcased are in the vanguard of protecting data and sensitive information under threat - the threat of digital information being made available to unscrupulous sources, and at times just pure vandalism. There are very few businesses, organizations or even individuals left in this country that don't use electronics today. The Electronic Revolution has been all-encompassing. Remaining vestiges of 'old world' practices - like manually writing or recording transactions or events, or the time-honored tradition of 'hiding money under the mattress' - have all but disappeared. So, along with the use of bows and arrows and pony dispatch riders, these are becoming historical markers strewn along the path of progress. The Celebrity Experts(r) in this book are people who are in business to protect digital information. In addition to unscrupulous sources that wish to profit from competitive information, businesses also have to deal with governmental regulations that ensure both consumers privacy as well as organizational transparency as well. Penalties for not adopting legislated governmental requirements in medical, financial and various other industries are severe. The information herein highlights the usefulness and ability of these experts - and their expertise is varied. We should not be surprised that electronic systems are "Under Attack," and also, that these Celebrity Experts(r) are not merely qualified, but more importantly, experienced in helping stave off the inevitable attacks that businesses, governments and organizations face daily. Using such expertise is a form of insurance, without which the cost of remediation can be devastatin

We depend on information and information technology (IT) to make many of our day-to-day tasks easier and more convenient. Computers play key roles in transportation, health care, banking, and energy. Businesses use IT for payroll and accounting, inventory and sales, and research and development. Modern military forces use weapons that are increasingly coordinated through computer-based networks. Cybersecurity is vital to protecting all of these functions. Cyberspace is vulnerable to a broad spectrum of hackers, criminals, terrorists, and state actors. Working in cyberspace, these malevolent actors can steal money, intellectual property, or classified information; impersonate law-abiding parties for their own purposes; damage important data; or deny the availability of normally accessible services. Cybersecurity issues arise because of three factors taken together - the presence of malevolent actors in cyberspace, societal reliance on IT for many important functions, and the presence of vulnerabilities in IT systems. What steps can policy makers take to protect our government, businesses, and the public from those would take advantage of system vulnerabilities? At the Nexus of Cybersecurity and Public Policy offers a wealth of information on practical measures, technical and nontechnical challenges, and potential policy responses. According to this report, cybersecurity is a never-ending battle; threats will evolve as adversaries adopt new tools and techniques to compromise security. Cybersecurity is therefore an ongoing process that needs to evolve as new threats are identified. At the Nexus of Cybersecurity and Public Policy is a call for action to make cybersecurity a public safety priority. For a number of years, the cybersecurity issue has received increasing public attention; however, most policy focus has been on the short-term costs of improving systems. In its explanation of the fundamentals of cybersecurity and the discussion of potential policy responses, this book will be a resource for policy makers, cybersecurity and IT professionals, and anyone who wants to understand threats to cyberspace.

Advanced Persistent Security covers secure network design and implementation, including authentication, authorization, data and access integrity, network monitoring, and risk assessment. Using such recent high profile cases as Target, Sony, and Home Depot, the book explores information security risks, identifies the common threats organizations face, and presents tactics on how to prioritize the right countermeasures. The book discusses concepts such as malignant versus malicious threats, adversary mentality, motivation, the economics of cybercrime, the criminal infrastructure, dark webs, and the criminals organizations currently face. - Contains practical and cost-effective recommendations for proactive and reactive protective measures - Teaches users how to establish a viable threat intelligence program - Focuses on how social networks present a double-edged sword against security programs

This guide empowers network and system administrators to defend their information and computing assets--whether or not they have security experience. Skoudis presents comprehensive, insider's explanations of today's most destructive hacker tools and tactics, and specific, proven countermeasures for both UNIX and Windows environments.

This book constitutes the refereed proceedings of the 18th International Conference on Computer-Aided Systems Theory, EUROCAST 2022, held in Las Palmas de Gran Canaria, Spain, during February 20–25, 2022. The 77 full papers included in this book were carefully reviewed and selected from 110 submissions. They were organized in topical sections as follows: Systems Theory and Applications, Theory and Applications of Metaheuristic Algorithms, Model-Based System Design, Verification and Simulation, Applications of Signal Processing Technology, Artificial Intelligence and Data Mining for Intelligent Transportation Systems and Smart Mobility, Computer Vision, Machine Learning for Image Analysis and Applications, Computer and Systems Based Methods and Electronic Technologies in Medicine, Systems in Industrial Robotics, Automation and IoT, Systems Thinking. Relevance for Technology, Science and Management Professionals.

In 2013, the FBI started posting a new most wanted list—not for kidnappers, murderers, or armed robbers, but for online crooks. These "Cyber's Most Wanted" criminals have committed serious offenses ranging from hijacking Internet traffic to spying on businesses and governments. They steal online passwords and financial information, break into online bank accounts, install malicious software on computers, and hack into computers via spam and phishing e-mails. Cyber crime is serious business. Internet security companies report that worldwide cyber crimes cost consumers about $113 billion per year. Cyber crimes cost businesses around the world even more, up to $500 billion each year. Technology experts continue to improve security software, but the attacks keep coming. Hackers are hitting electrical power grids, oil and gas pipelines, and other critical national infrastructures. Cyber criminals relentlessly strike corporate computers, trying to steal financial data, industrial blueprints, and business plans. They steal passwords from personal computers, which in turn can give them access to credit card, Social Security, and bank account numbers. Some cyber criminals steal military secrets. Others disrupt the workings of governments and political organizations. Many cyber crooks are lone individuals while others work in gangs. Many cyber criminals use botnets, or armies of robot computers, to inflict massive damage that could not be accomplished with individual computers alone. Who are these criminals and what motivates them? How can we stop them—and what might happen if we don't?

This volume presents the reader with an interesting and, at times, provocative selection of contemporary thinking about cybercrimes and their regulation. The contributions cover the years 2002-2007, during which period internet service delivery speeds increased a thousand-fold from 56kb to 56mb per second. When combined with advances in networked technology, these faster internet speeds not only made new digital environments more easily accessible, but they also helped give birth to a completely new generation of purely internet-related cybercrimes ranging from spamming, phishing and other automated frauds to automated crimes against the integrity of the systems and their content. In order to understand these developments, the volume introduces new cybercrime viewpoints and issues, but also a critical edge supported by some of the new research that is beginning to challenge and surpass the hitherto journalistically-driven news stories that were once the sole source of information about cybercrimes.
