The correct answer is 'AWS Artifact'. It is the designated portal for on-demand access to security and compliance reports and AWS' accreditation status. Users employ this service to download necessary documentation, which enables streamlined compliance checks, adherence to legal requirements, and simplified risk assessments. Contrary to options like Amazon CloudWatch or CloudTrail, which focus on operational health monitoring and audit logging respectively, or Security Hub for security checks, none of them serve the purpose of distributing compliance documentation.
