Security Architecture

Security architecture is the design framework that describes how security controls are positioned within your IT environment to protect systems and data. It encompasses network topology, security zones, data flow patterns, authentication systems, encryption deployment, and the integration of security tools into a cohesive defensive system.

A well-designed security architecture implements defense in depth, segments sensitive data environments, places controls at appropriate boundaries, and ensures that security tools work together rather than as isolated components. Your security architecture should be documented and reviewed as part of your System Security Plan.
