Definition
Security Architecture is the way systems, processes and safeguards are designed to provide an appropriate level of Asset protection and reduce Risk.
Human Explanation
Good Security Architecture makes safeguards work together as one coherent system.
Why it Matters
Without suitable architecture, even good individual safeguards may leave gaps that enable a successful Attack.
Conceptual Boundary
Security Architecture is not a list of products or devices. It describes how protection elements work together.
Practical Perspective
Security is most effective when included in system design rather than added after implementation.
