Overview
Security Architecture is the practice of designing a robust and resilient security framework that aligns with an organization's business goals and risk tolerance. It involves the integration of people, processes, and technology to create a 'defense in depth' strategy.
Key Components
- Network Security Design: Firewalls, VPNs, segmentation, and intrusion detection.
- Identity and Access Management (IAM): Authentication, authorization, and directory services.
- Data Protection: Encryption, DLP, and backup strategies.
- Application Security: Secure coding practices and testing frameworks.
- Cloud Security: Securing resources in public, private, and hybrid clouds.
- Governance and Compliance: Aligning the architecture with industry standards (e.g., NIST, ISO).
Importance
A well-designed security architecture ensures that security is built-in rather than bolted-on, making the organization more resilient to attacks and easier to manage.
