How to Execute AWS Security Hub Findings Integration with ISO 27001:2022 Annex A.12 Operations Security Controls for Multi-Account Cloud Governance

What operational security controls does ISO 27001:2022 Annex A.12 require?

ISO 27001:2022 Annex A.12 Operations Security contains 14 controls covering operational procedures, protection from malware, backup procedures, logging and monitoring, control of operational software, technical vulnerability management, information systems audit considerations, and restrictions on software installation. These controls focus on ensuring secure operations of information processing facilities.

Key controls include A.12.1.1 (Operating procedures and responsibilities), A.12.2.1 (Protection from malware), A.12.3.1 (Information backup), A.12.4.1 (Event logging), A.12.4.2 (Protection of log information), A.12.4.3 (Administrator and operator logs), A.12.4.4 (Clock synchronization), A.12.6.1 (Management of technical vulnerabilities), and A.12.6.2 (Restrictions on software installation).

For cloud environments, these controls require continuous monitoring, automated incident response, centralized logging, and systematic vulnerability management across all cloud resources and accounts.

How does AWS Security Hub support multi-account security operations management?

AWS Security Hub aggregates security findings from multiple AWS security services and third-party tools across multiple accounts within an AWS Organization. It provides centralized visibility into security posture, compliance status, and security trends across distributed cloud infrastructure.

Security Hub integrates with services including Amazon GuardDuty, Amazon Inspector, AWS Config, AWS Systems Manager Patch Manager, Amazon Macie, AWS Firewall Manager, and numerous third-party security tools. This integration enables comprehensive security monitoring that spans compute, network, data, and application layers.

The service uses AWS Security Finding Format (ASFF) to normalize findings from different sources, enabling consistent analysis and response procedures. Security Hub also provides compliance scorecards for standards including AWS Foundational Security Standard, CIS AWS Foundations Benchmark, and PCI DSS.

What are the key mapping points between Security Hub findings and ISO 27001 A.12 controls?

The integration between AWS Security Hub and ISO 27001:2022 Annex A.12 creates specific evidence collection and operational control points:
