The book's insistence on starting with the business outcome—rather than the technology tool—is the perfect cure for the "vendor sprawl" that plagues many modern IT departments.

SABSA is the gold standard for business-driven security architecture. It uses a matrix model based on six layers of abstraction, answering six fundamental questions: The layers of the SABSA matrix include: As Sherwood, Clark, and Lynas wrote: Security is

The core argument presented in the "Enterprise Security Architecture: A Business-Driven Approach" PDF is a direct challenge to conventional wisdom. Historically, security was treated as an inhibitor—a necessary set of restrictions placed upon the business.
