Access Control Logs

[All Actors]
1. Physical Access Control Integration: Use auditable access control systems (e.g., smart badges, biometrics) to monitor entry points where AI-related infrastructure or data is hosted. Synchronize physical access events with logical access logs for comprehensive visibility.

2. Centralized Logging and Monitoring: Collect and analyze logs from both physical entry systems and AI-specific events (model training, inference requests) in a unified monitoring environment. Enable real-time detection of anomalies by correlating physical entry with system activities.

3. Logging Security and Retention: Store physical access logs and AI event logs in an encrypted, access-controlled repository. Enforce defined retention periods based on regulatory requirements and organizational policies. Protect logs from tampering with immutability checks or other integrity mechanisms.

4. Automated Alerts and Anomaly Detection: Implement rule-based or AI-driven analytics to detect unusual patterns (e.g., after-hours facility entry followed by large-scale data transfers). Configure automated alerts to escalate suspicious activity to incident response teams.

5. Incident Response and Collaboration: Document clear escalation paths for AI-related security incidents involving physical intrusions. Share relevant logs and coordinate investigations across internal teams and external AI service providers to ensure swift remediation.

6. Regular Reviews and Continuous Improvement: Schedule periodic reviews that reconcile provider-side logs with consumer-side records, identifying discrepancies in physical or system access. Update log requirements, retention policies, and incident response playbooks in line with new AI use cases or emerging threats.

1. Inquiring with Control Owners

1.1 Conduct interviews with personnel responsible for monitoring and logging physical access using auditable access control systems for cloud infrastructure and AI processing facilities to understand their processes for tracking, recording, and reviewing physical access to data centers, compute clusters, and customer workload environments. Verify their understanding of access control system monitoring capabilities for cloud infrastructure, logging procedures for physical access to customer tenant facilities and AI processing resources, and audit trail requirements that ensure all physical access activities affecting infrastructure security and customer data protection are properly documented and reviewable.

2. Inspecting Records and Documents

2.1 Verify physical access control systems are in place for all cloud infrastructure environments, including data centers, AI processing clusters, customer tenant facilities, and compute resource centers.

2.2 Check logging mechanisms capture physical access timestamps, user identity, and location for cloud infrastructure facilities and customer workload environments.

2.3 Confirm physical access logs are retained in accordance with customer protection and regulatory compliance requirements for cloud infrastructure operations.

2.4 Validate alerts are generated for unauthorized or after-hours physical access to cloud infrastructure facilities and customer data centers.

2.5 Review role-based access controls to ensure only authorized infrastructure personnel can retrieve physical access logs for cloud environments.

2.6 Confirm periodic audits assess physical access adherence across all cloud infrastructure facilities and customer data protection areas.

2.7 Examine whether physical access logs are integrated into centralized SIEM systems for correlation with cloud infrastructure security and customer protection events.

2.8 Verify encryption is applied to stored physical access logs for cloud infrastructure facilities.

2.9 Review monitoring procedures and capabilities of the physical access control system to ensure real-time visibility into physical access events affecting cloud infrastructure and customer environments.

2.10 Validate that the access control system provides comprehensive audit trails with tamper-evident logging for all physical access activities in cloud infrastructure and customer facilities.

2.11 Examine backup and recovery procedures for cloud infrastructure physical access control system logs to ensure continuity of audit capabilities for customer protection and regulatory compliance.

2.12 Verify CSP data center physical access logs meet ISO/IEC 27001 and SOC 2 standards.

2.13 Ensure detailed audit trails exist for infrastructure used by regulated or high-risk tenants.

2.14 Check physical access logs are securely stored and cryptographically protected.

2.15 Confirm that access to physical access log systems themselves is restricted and monitored.

2.16 Validate that all physical access events are automatically reconciled with badge activity.

2.17 Review retention and redaction protocols for tenant-specific physical access logs.

2.18 Confirm customer audit rights for physical access under contractual obligations.

2.19 Ensure physical access logs are regularly shared with tenants under shared responsibility models.

2.20 Verify physical access controls and logging meet SOX compliance requirements for financial reporting systems and customer data protection.

2.21 Validate physical access monitoring supports SOC audit requirements and control effectiveness testing.
