Risk Analysis And Security Countermeasure Selection

When properly conducted, risk analysis enlightens, informs, and illuminates, helping management organize their thinking into properly prioritized, cost-effective action. Poor analysis, on the other hand, usually results in vague programs with no clear direction and no metrics for measurement. Although there is plenty of information on risk analysis

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.

Deploying an appropriate collection of information security countermeasures in an organization should result in high-level blocking power against existing threats. In this chapter, a new knapsack-based approach is proposed for finding out which subset of countermeasures is the best at preventing probable security attacks. In this regard, an effectiveness score is defined for each countermeasure based on its mitigation level against all threats. Organizations are always looking for more effective low-cost solutions, so another consideration is that the implementation cost of the selected countermeasure portfolio should not exceed the allocated budget. Following the knapsack idea, the implementation cost of each countermeasure and its effectiveness, defined as inputs and the best subset, are chosen with respect to budget limits. Our results are compared with similar research and recommend the same countermeasure portfolio.

The risk management process supports executive decision-making, allowing managers and owners to perform their fiduciary responsibility of protecting the assets of their enterprises. This crucial process should not be a long, drawn-out affair. To be effective, it must be done quickly and efficiently. Information Security Risk Analysis, Second Edition enables CIOs, CSOs, and MIS managers to understand when, why, and how risk assessments and analyses can be conducted effectively. This book discusses the principle of risk management and its three key elements: risk analysis, risk assessment, and vulnerability assessment. It examines the differences between quantitative and qualitative risk assessment, and details how various types of qualitative risk assessment can be applied to the assessment process. The text offers a thorough discussion of recent changes to FRAAP and the need to develop a pre-screening method for risk assessment and business impact analysis.

Risk is a cost of doing business. The question is, "What are the risks, and what are their costs?" Knowing the vulnerabilities and threats that face your organization's information and systems is the first essential step in risk management. Information Security Risk Analysis shows you how to use cost-effective risk analysis techniques to id

This book describes the risk management methodology as a specific process, a theory, or a procedure for determining your assets, vulnerabilities, and threats and how security professionals can protect them. Risk Management for Security Professionals is a practical handbook for security managers who need to learn risk management skills. It goes beyond the physical security realm to encompass all risks to which a company may be exposed. Risk Management as presented in this book has several goals: Provides standardized common approach to risk management through a framework that effectively links security strategies and related costs to realistic threat assessment and risk levels Offers flexible yet structured framework that can be applied to the risk assessment and decision support process in support of your business or organization Increases awareness in terms of potential loss impacts, threats and vulnerabilities to organizational assets Ensures that various security recommendations are based on an integrated assessment of loss impacts, threats, vulnerabilities and resource constraints Risk management is essentially a process methodology that will provide a cost-benefit payback factor to senior management. Provides a stand-alone guide to the risk management process Helps security professionals learn the risk countermeasures and their pros and cons Addresses a systematic approach to logical decision-making about the allocation of scarce security resources

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.
