This book investigates the challenge of establishing a consistent, scalable methodology for evaluating and mitigating security risks within complex information technology infrastructures. John McCumber, a recognized authority in information assurance, leverages his foundational 'McCumber Cube' framework to provide a structured approach that remains relevant despite the rapid evolution of hardware and software. By focusing on the core attributes of information security, the author argues that effective risk management relies on repeatable processes rather than reactive, technology-specific patches.

Experts frequently cite this work as a foundational text for understanding the structural components of information assurance. Readers often note that while the technology discussed is dated, the underlying methodology remains highly applicable for modern security professionals seeking a systematic approach to risk assessment.
