AWS Audit Manager is specifically designed to help organizations continuously audit their AWS usage against compliance frameworks and generate audit-ready reports. According to AWS Certified Security – Specialty documentation, Audit Manager includes AWS managed frameworks for compliance standards, including PCI DSS v4.0.

Audit Manager automatically collects evidence from AWS services such as API Gateway, Lambda, RDS, CloudTrail, and Config, and maps the evidence directly to PCI DSS controls. Importantly, Audit Manager allows compliance teams to upload and attach manual evidence, which is a key requirement in this scenario.

Option C provides visibility into control status but does not support adding manual evidence. Option B evaluates configuration compliance but does not generate formal compliance reports. Option A requires extensive manual effort and is not aligned with PCI reporting workflows.

AWS documentation positions Audit Manager as the authoritative service for compliance reporting and audit evidence management.

AWS Compliance Reporting Best Practices

AWS Organizations service control policies (SCPs) are designed to enforce preventive guardrails across accounts without requiring application-level changes. According to the AWS Certified Security – Specialty documentation, SCPs can restrict specific API actions or require certain condition keys to enforce security standards centrally. AWS Lambda function URLs support two authentication modes: AWS_IAM and NONE. When the authentication type is set to NONE, the function URL becomes publicly accessible, which introduces a significant security risk in production environments.

By using an SCP that explicitly denies the lambda:CreateFunctionUrlConfig and lambda:UpdateFunctionUrlConfig actions when the lambda:FunctionUrlAuthType condition key equals NONE, the organization ensures that unauthenticated function URLs cannot be created or modified in production accounts. This enforcement occurs at the AWS Organizations level and applies automatically to all accounts within the specified organizational units (OUs). Developers are not required to change their workflows or add additional controls, satisfying the requirement of no additional developer effort.

Option A relates to browser-based access controls and does not provide authentication or authorization enforcement. Option B is not valid because AWS WAF cannot be attached directly to AWS Lambda function URLs. Option C is incorrect because SCPs do not grant permissions; they only limit permissions. AWS documentation clearly states that SCPs define maximum available permissions and are evaluated before IAM policies.

This approach aligns with AWS best practices for centralized governance, least privilege, and preventive security controls.

The immediate error indicates that the certificate information in IAM no longer matches the identity provider’s SAML signing metadata. AWS troubleshooting guidance states that this error can occur when federation metadata changes, such as when an expired or rotated certificate is updated, and the fix is to download the updated SAML metadata file from the IdP. The metadata must be uploaded to the existing IAM SAML provider used by the role trust relationship. Creating a new provider entity would require additional role trust and assertion changes and is not the clean immediate fix. For future rotations, adding the new certificate before expiration and updating metadata prevents another outage during the certificate lifecycle.

Amazon Detective is specifically designed to help security teams investigate and visualize the root cause of security findings. According to AWS Certified Security – Specialty documentation, Detective automatically aggregates and correlates data from GuardDuty, CloudTrail, and VPC Flow Logs to provide interactive visualizations and timelines.

Detective enables investigators to pivot from GuardDuty findings to IAM roles, API calls, network traffic, and resource behavior. This makes it the most efficient tool for understanding how IAM roles were used during suspicious activity.

Amazon Inspector focuses on vulnerability assessment, not behavioral investigation. Security Hub aggregates findings but does not provide deep investigation graphs. Manual analysis with Athena requires significantly more effort.

AWS guidance explicitly recommends Amazon Detective for root cause analysis and visualization of security incidents.

IAM Identity Center account instances are designed for isolated deployments of supported AWS managed applications in a single AWS account. AWS documentation states that account instances should be used for isolated users who need applications in one account, and they remain bound to the account in which they are created. This matches the requirement: third-party users cannot be added to the company’s main IdP, and access must be isolated from the organization-level IAM Identity Center identity source. Amazon Cognito identity pools do not configure authentication for IAM Identity Center integrated AWS managed applications in this pattern. IAM SAML roles in the management account would not isolate the application account cleanly. IAM Identity Center supports one identity source per instance, so adding a second identity source to the organization instance is not the right design.
