+# Standards Reference: CISA Zero Trust Maturity Model
+
+## Primary Standards
+
+### CISA Zero Trust Maturity Model v2.0 (April 2023)
+- **Source**: Cybersecurity and Infrastructure Security Agency
+- **Scope**: Federal agencies and organizations implementing zero trust
+- **Five Pillars**: Identity, Devices, Networks, Applications & Workloads, Data
+- **Four Maturity Stages**: Traditional, Initial, Advanced, Optimal
+- **Cross-Cutting**: Visibility & Analytics, Automation & Orchestration, Governance
+
+### NIST SP 800-207: Zero Trust Architecture
+- **Published**: August 2020
+- **Tenets**: Never trust, always verify; assume breach; least privilege access
+- **Deployment Models**: Device agent/gateway, enclave, resource portal
+- **Key Requirement**: Policy decision point (PDP) and policy enforcement point (PEP)
+
+### Executive Order 14028: Improving the Nation's Cybersecurity
+- **Signed**: May 12, 2021
+- **Mandate**: Federal agencies must adopt zero trust architecture
+- **Timeline**: Agencies required to develop zero trust implementation plans
+
+### OMB Memorandum M-22-09: Federal Zero Trust Strategy
+- **Published**: January 2022
+- **Requirements per pillar**:
+  - Identity: Phishing-resistant MFA for all staff
+  - Devices: EDR deployed across federal endpoints
+  - Networks: DNS traffic encrypted, HTTP traffic encrypted
+  - Applications: Application security testing in CI/CD
+  - Data: Data categorization and automated classification
