There are so many reference models and open-source material available for enterprise architects – so it isn’t surprising that some of this material is less well known. One useful specialized resource is free-use the open-source Security Architecture development and management method and framework – SABSA.

SABSA stands for ‘Sherwood Applied Business Security Architecture’. This summary is from the official SABSA website:

SABSA is a proven methodology for developing business-driven, risk and opportunity focused Security Architectures at both enterprise and solutions level that traceably support business objectives. It is also widely used for Information Assurance Architectures, Risk Management Frameworks, and to align and seamlessly integrate security and risk management into IT Architecture methods and frameworks.

SABSA is comprised of a series of integrated frameworks, models, methods and processes, used independently or as an holistic integrated enterprise solution, including:

  • Business Requirements Engineering Framework (known as Attributes Profiling)

  • Risk and Opportunity Management Framework

  • Policy Architecture Framework

  • Security Services-Oriented Architecture Framework

  • Governance Framework

  • Security Domain Framework

  • Through-life Security Service Management & Performance Management Framework

The SABSA Institute develops and maintains the method and certifies and accredits the professional Architects who use it in approximately 50 countries around the world.
