# Workflows: CISA Zero Trust Maturity Model Implementation
|
|
|
|
## Workflow 1: Initial Maturity Assessment
|
|
|
|
```
|
|
Step 1: Establish Assessment Team
|
|
- Identify stakeholders from IT, security, compliance, and business units
|
|
- Assign pillar owners for each of the five ZTMM pillars
|
|
- Define assessment timeline and reporting cadence
|
|
|
|
Step 2: Inventory Current Capabilities
|
|
- Identity: Catalog authentication methods, identity providers, MFA coverage
|
|
- Devices: Enumerate all endpoints, document endpoint security tools
|
|
- Networks: Map network architecture, segmentation, encryption status
|
|
- Applications: List all applications, classify access controls
|
|
- Data: Identify data repositories, classification, DLP status
|
|
|
|
Step 3: Map to ZTMM Stages
|
|
- For each pillar, evaluate each function against the four maturity stages
|
|
- Document evidence for current stage determination
|
|
- Identify gaps between current and target maturity
|
|
- Rate cross-cutting capabilities (visibility, automation, governance)
|
|
|
|
Step 4: Produce Assessment Report
|
|
- Pillar-by-pillar maturity scores
|
|
- Gap analysis with prioritized recommendations
|
|
- Quick wins vs. long-term transformation items
|
|
- Resource requirements and estimated timelines
|
|
```
|
|
|
|
## Workflow 2: Identity Pillar Advancement (Traditional to Advanced)
|
|
|
|
```
|
|
Phase A: MFA Deployment
|
|
1. Inventory all user accounts (privileged, standard, service)
|
|
2. Select phishing-resistant MFA solution (FIDO2/WebAuthn)
|
|
3. Deploy MFA for privileged accounts first
|
|
4. Extend MFA to all user accounts
|
|
5. Implement MFA for service accounts and APIs
|
|
6. Configure conditional access policies
|
|
|
|
Phase B: Identity Governance
|
|
1. Implement identity lifecycle management
|
|
2. Connect IAM to HR system for automated provisioning
|
|
3. Establish access certification reviews
|
|
4. Deploy identity threat detection
|
|
5. Implement just-in-time access for elevated privileges
|
|
|
|
Phase C: Continuous Verification
|
|
1. Integrate identity signals into access decisions
|
|
2. Deploy risk-based authentication
|
|
3. Implement session-level re-authentication for sensitive actions
|
|
4. Enable behavioral analytics for identity anomalies
|
|
```
|
|
|
|
## Workflow 3: Cross-Pillar Integration
|
|
|
|
```
|
|
Step 1: Establish Unified Policy Engine
|
|
- Define access policies that incorporate all five pillars
|
|
- Implement Policy Decision Point (PDP) per NIST 800-207
|
|
- Deploy Policy Enforcement Points (PEP) at all access boundaries
|
|
|
|
Step 2: Integrate Signal Sources
|
|
- Identity signals -> trust score component
|
|
- Device posture -> trust score component
|
|
- Network context -> trust score component
|
|
- Application risk -> trust score component
|
|
- Data sensitivity -> access control component
|
|
|
|
Step 3: Implement Continuous Evaluation
|
|
- Real-time trust scoring engine
|
|
- Dynamic policy adjustment based on risk
|
|
- Automated access revocation on policy violation
|
|
- Audit logging for all access decisions
|
|
|
|
Step 4: Measure and Report
|
|
- Track maturity progression per pillar quarterly
|
|
- Report to leadership with ZTMM scorecard
|
|
- Adjust roadmap based on threat landscape changes
|
|
- Document lessons learned for continuous improvement
|
|
```
|
|
|
|
## Workflow 4: Governance and Compliance Reporting
|
|
|
|
```
|
|
Step 1: Establish Zero Trust Governance Board
|
|
- Executive sponsor, CISO, pillar owners, compliance
|
|
- Monthly review of zero trust maturity progress
|
|
- Annual strategic review and roadmap adjustment
|
|
|
|
Step 2: Continuous Compliance Monitoring
|
|
- Map ZTMM controls to OMB M-22-09 requirements
|
|
- Automate evidence collection for each pillar
|
|
- Generate compliance dashboards
|
|
- Prepare for FISMA and other audit requirements
|
|
|
|
Step 3: Reporting to CISA
|
|
- Submit agency zero trust implementation plan
|
|
- Provide quarterly progress updates
|
|
- Document deviations and remediation plans
|
|
```
