Security Architecture is important for making sure security is built into the business process and systems of the organization.
Key outcomes of security architecture include:
Security and control specifications serving as guidance for implementing and auditing systems and operations
Security architecture patterns for reuse and consistency across technical solutions
Security guiding principles for consideration in change initiatives
Security architecture is closely aligned with IT and infrastructure architecture, and provides best practice guidance on an organizations security policies. Risk management is another important discipline relating to and supporting security architecture. Risks are identified in the context of the security structures and policies.
