🚫 Segregation of Duties

Role-based access control supports segregation of duties principles by enforcing separation between incompatible functions. See 🚫 Segregation of Duties Policy for:

Incompatible role pairs requiring separation
Single-person organization compensating controls
Temporal and tool-based separation mechanisms
Audit trail and external validation requirements

Key access control aspects supporting SoD:

Least Privilege: Default to minimum permissions required for role
Time-Limited Elevation: Administrator access granted just-in-time with automatic expiration
Audit Trail: All permission changes and elevated access logged in CloudTrail
Quarterly Review: Access permissions reviewed against principle of least privilege

🏢 Single-Person Company Adaptation

Traditional Multi-Person Requirement

Industry best practice and NIST 800-53 guidance recommend separation of duties for access control administration:

Access Provisioner: Administrator who grants/revokes access rights
Access Reviewer: Independent security team member who validates access appropriateness
Audit Function: Separate audit team reviewing access control compliance

Traditional separation provides:

Independent validation of access decisions
Detection of unauthorized access grants
Prevention of insider threats through collusion resistance
Compliance with segregation of duties requirements

Typical Process:

User requests access (or access change)
Manager/provisioner approves and grants access
Separate security team conducts quarterly access review
Independent auditor validates access control effectiveness annually

Hack23 AB Single-Person Adaptation

As CEO/Founder is the sole employee and performs all roles (access provisioner, reviewer, and user), traditional multi-person access review is not possible. Instead, Hack23 AB implements automated tool validation + external audit model:

🎯 CEO As Access Administrator

Roles Consolidated:

Access Provisioner (grants/revokes all access)
Access Reviewer (validates access appropriateness)
Primary User (uses all systems for business operations)

Limitations of Single-Person Model:

No independent human review of access decisions
Self-review cannot detect own errors or excessive permissions
Risk of "privilege creep" without external validation

🎯 Automated Access Analysis

AWS IAM Access Analyzer (Primary Compensating Control):

Feature	Capability	Business Value	Validation Frequency
Unused Access Detection	Identifies credentials and permissions not used in 90+ days	Reduces attack surface, enforces least privilege	Real-time continuous
External Access Analysis	Detects resources shared outside AWS organization	Prevents unauthorized external access	Real-time continuous
Policy Validation	Validates IAM policies against AWS security best practices	Ensures secure policy configuration	On policy change
Access Preview	Simulates policy changes before implementation	Prevents unintended access grants	Pre-deployment

GitHub Security Features (Development Platform):

Organization Audit Log: Complete history of all access changes, permission grants
Security Alerts: Notifications for suspicious access patterns or unauthorized changes
Required Reviewers: Branch protection requires PR approval (self-review documented as accepted risk)
Dependency Review: Automated analysis of third-party access via dependencies

🎯 External Validation Model

Annual External Auditor Review:

Validation Activity	Auditor Scope	Frequency	Deliverable
Access Control Effectiveness	Review access grants, permissions, MFA compliance	Annual	Audit report with findings and recommendations
Least Privilege Validation	Verify users have minimum necessary permissions	Annual	Excessive permission identification
Segregation of Duties Assessment	Evaluate compensating controls for SoD violations	Annual	Control adequacy assessment
Compliance Verification	Validate ISO 27001/NIST CSF alignment	Annual	Compliance attestation

Compensating Controls

Control Type	Implementation	ISO 27001 Alignment	Effectiveness
🤖 AWS IAM Access Analyzer	Continuous automated analysis of access permissions, unused access detection	A.5.18 - Access Rights Management	Provides independent (machine) validation superior to manual review
📊 Quarterly CEO Self-Review	CEO reviews all access grants, permissions, MFA status using IAM Access Analyzer findings	A.9.2.5 - Review of User Access Rights	Systematic review process with automated tool assistance
🔍 External Annual Audit	Independent auditor validates access control effectiveness and least privilege compliance	A.5.18 - Access Rights Management	Independent human validation catches systematic issues
📋 Complete Audit Trail	AWS CloudTrail + GitHub Audit Log provide tamper-evident access change history	A.8.15 - Logging	Enables retrospective review and forensic investigation
⏱️ Automated Alerts	Real-time notifications for suspicious access patterns, policy changes, external sharing	A.8.16 - Monitoring Activities	Immediate detection of access anomalies

ISO 27001:2022 Compliance

This adaptation maintains control objectives of A.5.18 (Access Rights Management) and A.9.2.5 (Review of User Access Rights) by ensuring:

✅ Access Rights Allocation: CEO manages all access with documented procedures
✅ Regular Reviews: Quarterly CEO review + AWS IAM Access Analyzer continuous monitoring
✅ Least Privilege: Automated unused access detection enforces minimum permissions
✅ Access Right Removal: Systematic removal of unused credentials and permissions
✅ Independent Validation: External auditor provides independent human review annually

Alignment with ISO 27001:2022 Guidance: Annex A.9.2.5 requires "regular reviews" of access rights but does not mandate separate reviewer. The standard allows for "automated tools" to support access reviews. Single-person operations achieve control objectives through automated analysis tools (IAM Access Analyzer) providing machine-based independence + external auditor validation rather than dedicated security team review.

Superiority of Automated Approach: AWS IAM Access Analyzer provides continuous real-time monitoring superior to quarterly human review. Machine analysis detects unused access, excessive permissions, and policy violations more consistently and comprehensively than manual review.

Risk Acceptance

Risk Description: Single-person access administration increases risk of self-review bias and excessive permissions compared to independent security team review. CEO may not detect own errors in access grants or recognize privilege creep.

See 📉 Risk Register for current risk assessment, likelihood/impact scoring, and treatment status.

Compensating Controls Summary:

Automated superiority: AWS IAM Access Analyzer continuous monitoring exceeds quarterly human review effectiveness
Machine independence: Automated tool provides independent validation without human bias
Limited scope: Single-user environment (CEO) has minimal access control complexity
External validation: Annual auditor review provides independent human oversight
Complete audit trail: CloudTrail + GitHub logs enable retrospective forensic review

Monitoring & Review:

Real-Time: AWS IAM Access Analyzer findings reviewed immediately when triggered
Quarterly: CEO comprehensive access review using IAM Access Analyzer findings dashboard
Annual: External auditor validates access control effectiveness and compensating controls
