Enterprise Security Architecture (ESA) Design

Enterprise Security Architecture (ESA) is a structured approach to designing and implementing security controls, policies, and strategies to protect an organization's IT infrastructure, applications, and data. It aligns security with business objectives, ensuring that security measures support and enable business operations while minimizing risks.

✅ Security Governance & Risk Management

✅ Identity & Access Management (IAM)

✅ Network Security Architecture

✅ Data Security & Encryption

✅ Application Security

✅ Endpoint & Mobile Security

✅ Security Monitoring & Incident Response

✅ Compliance & Regulatory Requirements

Frameworks for Enterprise Security Architecture

SABSA (Sherwood Applied Business Security Architecture) – Risk-driven security architecture TOGAF (The Open Group Architecture Framework) – Security integrated into enterprise architecture NIST Cybersecurity Framework – Guidelines for risk management and security controls Zero Trust Architecture – "Never trust, always verify" security model MITRE ATT&CK – Threat intelligence framework for security defense Align security architecture with business objectives Adopt a layered security approach (Defense in Depth) Automate security controls where possible Continuously monitor and improve security posture Educate and train employees on cybersecurity awareness.
Enterprise Security Architecture (ESA) frameworks provide structured approaches to designing, implementing, and managing security across an organization’s IT infrastructure. Several widely recognized frameworks guide enterprises in aligning security strategies with business objectives. The Sherwood Applied Business Security Architecture (SABSA) is a risk-driven framework that ensures security is integrated into business processes from the outset, emphasizing governance, risk management, and compliance. The The Open Group Architecture Framework (TOGAF) includes security as a key aspect of enterprise architecture, helping organizations integrate security controls within their broader IT strategy. The NIST Cybersecurity Framework (NIST CSF) provides guidelines for managing and reducing cybersecurity risks through five core functions: Identify, Protect, Detect, Respond, and Recover, making it a widely adopted framework for risk management and regulatory compliance.
