A fresh new approach to computer security by the authors of the 20-year best-selling classic Security in Computing. • •Introduces computer security the way today's practitioners want to learn it: by identifying threats, explaining the vulnerabilities that cause them, and presenting effective countermeasures. •Contains up-to-date coverage of security management, risk analysis, privacy, controls, forensics, insider attacks, human factors, trust, and more. •Includes 273 problems and 192 illustrations. In this book, the authors of the 20-year best-selling classic Security in Computing take a fresh, contemporary, and powerfully relevant new approach to introducing computer security. Organized around attacks and mitigations, the Pfleegers' new Analyzing Computer Security will attract readers' attention by building on the high-profile security failures they may have already encountered in the popular media. Each section starts with an attack description. Next, the authors explain the vulnerabilities that have allowed this attack to occur. With this foundation in place, they systematically present today's most effective countermeasures for blocking or weakening the attack. One step at a time, readers progress from attack/problem/harm to solution/protection/mitigation, building the powerful real-world problem solving skills they need to succeed as information security professionals. Analyzing Computer Security themes throughout, including effective security management and risk analysis; economics and quantitative study; privacy, ethics, and laws; and the use of overlapping controls.

In Securing VoIP Networks, two leading experts systematically review the security risks and vulnerabilities associated with VoIP networks and offer proven, detailed recommendations for securing them. Drawing on case studies from their own fieldwork, the authors address VoIP security from the perspective of real-world network implementers, managers, and security specialists. The authors identify key threats to VoIP networks, including eavesdropping, unauthorized access, denial of service, masquerading, and fraud; and review vulnerabilities in protocol design, network architecture, software, and system configuration that place networks at risk. They discuss the advantages and tradeoffs associated with protection mechanisms built into SIP, SRTP, and other VoIP protocols; and review key management solutions such as MIKEY and ZRTP. Next, they present a complete security framework for enterprise VoIP networks, and provide detailed architectural guidance for both service providers and enterprise users. 1 Introduction 2 VoIP Architectures and Protocols 3 Threats and Attacks 4 VoIP Vulnerabilites 5 Signaling Protection Mechanisms 6 Media Protection Mechanisms 7 Key Management Mechanisms 8 VoIP and Network Security Controls 9 A Security Framework for Enterprise VoIP Networks 10 Provider Architectures and Security 11 Enterprise Architectures and Security

This new edition of Risk Analysis and Security Countermeasure Selection presents updated case studies and introduces existing and new methodologies and technologies for addressing existing and future threats. It covers risk analysis methodologies approved by the U.S. Department of Homeland Security and shows how to apply them to other organizations, public and private. It also helps the reader understand which methodologies are best to use for a particular facility and demonstrates how to develop an efficient security system. Drawing on over 35 years of experience in the security industry, Thomas L. Norman provides a single, comprehensive reference manual for risk analysis, countermeasure selection, and security program development. The security industry has a number of practitioners and consultants who lack appropriate training in risk analysis and whose services sometimes suffer from conflicts of interest that waste organizations’ money and time. Norman seeks to fill the void in risk analysis training for those security consultants, thereby reducing organizations’ wasting of resources and potential vulnerability. This book helps you find ways to minimize cost and time spent in analyzing and countering security threats. Risk Analysis and Security Countermeasure Selection, Second Edition gives invaluable insight into the risk analysis process while showing how to use analyses to identify and create the most cost efficient countermeasures. It leads you from a basic to an advanced level of understanding of the risk analysis process. The case studies illustrate how to put each theory into practice, including how to choose and implement countermeasures and how to create budgets that allow you to prioritize assets according to their relative risk and select appropriate countermeasures according to their cost effectiveness.

Threat Assessment and Risk Analysis: An Applied Approach details the entire risk analysis process in accessible language, providing the tools and insight needed to effectively analyze risk and secure facilities in a broad range of industries and organizations. The book explores physical vulnerabilities in such systems as transportation, distribution, and communications, and demonstrates how to measure the key risks and their consequences, providing cost-effective and achievable methods for evaluating the appropriate security risk mitigation countermeasures. Users will find a book that outlines the processes for identifying and assessing the most essential threats and risks an organization faces, along with information on how to address only those that justify security expenditures. Balancing the proper security measures versus the actual risks an organization faces is essential when it comes to protecting physical assets. However, determining which security controls are appropriate is often a subjective and complex matter. The book explores this process in an objective and achievable manner, and is a valuable resource for security and risk management executives, directors, and students. Guides readers from basic principles to complex processes in a logical, building block fashion Provides a clear, step-by-step process for performing a physical security threat and risk analysis for any organization Covers quantitative and qualitative risks such as operational risk, legal risk, reputational risk, social risks, and economic risks Utilizes the Department of Homeland Security risk assessment framework and best practices, including CARVER, API/NPRA, and RAMCAP
