The modern dependence upon information technology and the corresponding information security regulations and requirements force companies to evaluate the security of their core business processes, mission critical data, and supporting IT environment. Combine this with a slowdown in IT spending resulting in justifications of every purchase, and security professionals are forced to scramble to find comprehensive and effective ways to assess their environment in order to discover and prioritize vulnerabilities, and to develop cost-effective solutions that show benefit to the business. A Practical Guide to Security Assessments is a process-focused approach that presents a structured methodology for conducting assessments. The key element of the methodology is an understanding of business goals and processes, and how security measures are aligned with business risks. The guide also emphasizes that resulting security recommendations should be cost-effective and commensurate with the security risk. The methodology described serves as a foundation for building and maintaining an information security program. In addition to the methodology, the book includes an Appendix that contains questionnaires that can be modified and used to conduct security assessments. This guide is for security professionals who can immediately apply the methodology on the job, and also benefits management who can use the methodology to better understand information security and identify areas for improvement.

This book is a detailed methodology of performing a security assessment. The book emphasizes the approach of first understanding the business and then the technology that supports it.

With the emphasis on the business driving security, this book presents a standard methodology for performing a security assessment as well as the reasons for doing it that way.
