Designing secure systems and infrastructure
Security Architecture involves designing, building, and maintaining the security structures and frameworks that protect an organization’s information systems and data.
Core Principles
- Defense in Depth - Multiple layers of security controls
- Least Privilege - Minimum necessary access
- Separation of Duties - Dividing critical functions
- Zero Trust - Never trust, always verify
- Secure by Design - Building security into systems from the start
Architecture Components
- Network security architecture
- Identity and access management
- Data protection and encryption
- Application security
- Cloud security architecture
- Endpoint security
Frameworks
- SABSA (Sherwood Applied Business Security Architecture)
- TOGAF Security Architecture
- NIST Cybersecurity Framework
- Zero Trust Architecture (ZTA)
Deliverables
- Security architecture documents
- Reference architectures
- Security standards and patterns
- Technology roadmaps
- Architecture review processes
