Security Compliance and Identity Domain Map organizes enterprise security into two core pillars: Security and Compliance (covering Shared Responsibility, Defense in Depth, Zero Trust, Encryption, Hashing, and GRC) and Identity (covering Authentication, Authorization, Identity Providers, Directory Services, and Federation). The diagram illustrates how Zero Trust architecture enforces MFA and Authentication, while Defense in Depth integrates Privileged Access Management (PAM) with RBAC and ABAC authorization models. This framework demonstrates that Identity is the Primary Security Perimeter, with Directory Services like Active Directory and federated Identity Providers anchoring access control across hybrid and cloud environments. Use this domain map to align security strategy, governance policies, and identity infrastructure with modern zero-trust principles and compliance requirements. Fork and customize this diagram to map your organization's specific security domains, regulatory obligations, and identity architecture decisions.
