Enterprise Security Architecture
A business-driven, enterprise-wide architecture that links security to strategy — from business context down to logical and physical design, so every control traces back to a goal.
What it is, and why it matters.
Enterprise security architecture is the top-down, business-driven discipline that connects security to the organisation's strategy across the whole enterprise. It works from business context and drivers through conceptual, logical, and physical layers — so that every security decision is traceable back to a business goal and a risk, rather than chosen in isolation. Where information security architecture designs the controls, enterprise security architecture sets the frame they sit in. It's how security stays aligned to the business as both evolve.
Who it affects.
Larger or more complex organisations — and those undergoing significant change — that need security to be coherent across the whole enterprise and genuinely tied to business strategy, not just technically sound in pockets.
What it involves.
Business context, drivers, and goals
Conceptual, logical, and physical architecture layers
Traceability from business goals to risks to controls
Alignment to the target operating model
