Cloud Controls Matrix (CCM)

**Current Version**: CCM v4.0 (released 2021) **Control Objectives**: 197 controls across 17 domains **Purpose**: Provide cloud-specific security controls framework **Scope**: Applies to all cloud service models (IaaS, PaaS, SaaS) and deployment models (public, private, hybrid, multi-cloud)

**Key Features**:

• Cloud-specific security controls
• Shared responsibility model alignment
• Framework harmonization (ISO, SOC, PCI, NIST, GDPR)
• CAIQ self-assessment tool
• CSA STAR certification program

17 CCM Domains (197 Controls)

1. A&A - Audit and Assurance (6 controls)

Independent verification and compliance validation.

**Key Controls**:

• **A&A-01**: Audit Planning - Scope, objectives, methodology
• **A&A-02**: Independent Audits - Third-party assessments (SOC 2, ISO 27001)
• **A&A-03**: Regulatory Mapping - Framework alignment documentation
• **A&A-04**: Audit Controls Assurance - Evidence collection and retention
• **A&A-05**: SOC 2 Reporting - AICPA attestation
• **A&A-06**: Annual Certification - Ongoing compliance validation

**Implementation Priorities**:

• SOC 2 Type II certification (annual)
• ISO 27001 certification
• Third-party penetration testing
• CAIQ self-assessment publication (CSA STAR Level 1)

2. AIS - Application & Interface Security (11 controls)

Secure software development and API protection.

**Key Controls**:

• **AIS-01**: Application Security - SDLC integration
• **AIS-03**: API Security - Authentication, authorization, rate limiting
• **AIS-04**: Automated Security Testing - SAST/DAST/IAST
• **AIS-10**: Secure Coding - OWASP Top 10 mitigation
• **AIS-11**: Third-Party Software - Vendor security assessment

**Cloud-Specific Considerations**:

• API-first architecture security
• Microservices security
• Serverless security (AWS Lambda, Azure Functions)
• Container security (Docker, Kubernetes)
• CI/CD pipeline security (DevSecOps)

**OWASP Top 10 Cloud Risks**:

1. Broken authentication and session management 2. Sensitive data exposure 3. Broken access control 4. Security misconfiguration 5. Cross-site scripting (XSS) 6. Insecure deserialization 7. Using components with known vulnerabilities 8. Insufficient logging and monitoring 9. SQL injection 10. Server-side request forgery (SSRF)

3. BCR - Business Continuity & Operational Resilience (11 controls)

High availability and disaster recovery.

**Key Controls**:

• **BCR-01**: Business Continuity Planning - BCP documentation
• **BCR-04**: Disaster Recovery - DR plan and testing
• **BCR-06**: Service Availability - SLA targets and monitoring
• **BCR-07**: Backup - 3-2-1 backup strategy
• **BCR-09**: Business Continuity Testing - Annual DR drills

**Cloud Resilience Patterns**:

• Multi-region deployment (active-active, active-passive)
• Auto-scaling and load balancing
• Database replication (synchronous, asynchronous)
• Chaos engineering (failure injection testing)
• Disaster recovery SLAs: RTO (Recovery Time Objective), RPO (Recovery Point Objective)

**SLA Tiers**:

• **99.9%** ("three nines"): 8.76 hours downtime/year
• **99.95%**: 4.38 hours downtime/year
• **99.99%** ("four nines"): 52.56 minutes downtime/year
• **99.999%** ("five nines"): 5.26 minutes downtime/year

4. CCC - Change Control & Configuration Management (9 controls)

Managing changes and maintaining secure configurations.

**Key Controls**:
