The best process preserves evidence while minimizing manual access. Security group isolation is a standard EC2 containment method, and detaching from Auto Scaling and load balancers prevents replacement or production routing changes during the investigation. Systems Manager Run Command is preferable to SSH or RDP because it executes scripted collection with auditable command history and avoids interactive login activity that can contaminate evidence. EBS snapshots preserve non-volatile disk data for later forensic analysis, and tagging the instance with incident metadata supports traceability and chain-of-custody workflows. Moving an instance between subnets is disruptive and unnecessary. State Manager is intended for ongoing configuration association, not immediate incident-specific forensic collection with the least overhead.

IAM Access Analyzer is the correct service for least-privilege review because it can analyze unused access and last accessed information for IAM identities. AWS documentation states that unused access analyzers can generate findings for access that has not been used within a configured period, with a selectable range up to 365 days. This directly matches the annual audit requirement. CloudTrail logs contain raw activity data, but manually reviewing 365 days of events for each identity is high effort and error-prone. AWS Config tracks configuration changes, not effective permission usage. Trusted Advisor can identify some security risks, but it does not provide the role-level and user-level last accessed analysis needed to remove unused permissions systematically.

Step 1:Obtain the SAML metadata fromIAM Identity Center.

Step 2:Obtain the SAML metadata from theexternal IdP.

Step 3:Configure theexternal IdP as the identity sourceinIAM Identity Center.

When integratingAWS IAM Identity Center (formerly AWS SSO)with anexternal identity provider (IdP)usingSAML 2.0, AWS requires a specific sequence of steps to establish trust and federation correctly.

Step 1: Obtain the SAML metadata from IAM Identity Center

IAM Identity Center acts as theservice provider (SP)in the SAML trust. The external IdP must trust IAM Identity Center, so the IdP needs IAM Identity Center’s SAML metadata first. This metadata contains critical information such as the SP entity ID, ACS (Assertion Consumer Service) URL, and signing certificate. Without this metadata, the external IdP cannot be configured to send assertions to AWS.

Step 2: Obtain the SAML metadata from the external IdP

After the external IdP is configured to trust IAM Identity Center, the IdP generates its own SAML metadata. This metadata includes the IdP entity ID, SSO endpoint, and signing certificate. IAM Identity Center requires this information to validate authentication assertions coming from the external IdP.

Step 3: Configure the external IdP as the identity source in IAM Identity Center

Once both metadata files are available, the security engineer configures the external IdP as theidentity sourcein IAM Identity Center. At this stage, IAM Identity Center imports the IdP metadata and establishes the SAML trust relationship. After this configuration, users authenticated by the external IdP can be federated into AWS accounts and applications via IAM Identity Center.

Why the other options are incorrect:

Creating an IAM role with an IdP API endpoint is used forIAM federation, not IAM Identity Center.

Automatic provisioning (SCIM) is optional and is configuredafterSAML federation is established.

Automatic provisioning must be enabled onboth sides, but it is not required to complete the core IdP integration.

This sequence follows AWS best practices for SAML-based federation with IAM Identity Center.

The company needs centralized, scalable protection acrossmany accountsfor bothexisting and futureAPI Gateway resources, with minimal ongoing effort.AWS Firewall Manageris specifically designed for this: it can centrally deploy and enforceAWS WAFprotections across AWS Organizations. By creating a Firewall ManagerWAF policy, the security team defines a single set of controls (for example, AWS Managed Rules for SQL injection protection andAWS Bot Control) and applies them automatically to in-scope resources across member accounts.

Critically, Firewall Manager can be configured toauto-remediate noncompliant resources, ensuring that if new API Gateway stages are created later, they are automatically brought under the policy without manual per-account work. This directly meets the “existing and future resources” requirement.

Options A, C, and D introduce higher operational overhead: per-API ACL creation plus AWS Config remediation (A) is more moving parts; Service Catalog plus detection/remediation (C) is indirect and heavy; and Security Hub + EventBridge + Lambda automation (D) is custom engineering and maintenance. Firewall Manager is the AWS-native centralized governance solution for multi-account WAF rollout and enforcement.
