Zorluk: OrtaSecurity Automation and Orchestration (SOAR)

A security analyst is configuring a Security Orchestration, Automation, and Response (SOAR) playbook to automatically handle alerts triggered when a cloud IAM access key is exposed in a public repository. Arrange the automated response workflow steps into the correct chronological sequence from first step to final step.

  1. 1Ingest the alert payload and query cloud audit logs to enrich the event with recent API activity associated with the exposed access key.
  2. 2Revoke active session tokens and attach an inline deny policy to the compromised IAM identity to prevent further unauthorized access.
  3. 3Generate a replacement access key pair and update the stored credential in the enterprise secrets manager.
  4. 4Send a notification containing the incident audit log and ticket reference to the application owner for validation and ticket closure.

Cevap

The correct execution sequence begins with event ingestion and log enrichment, followed by automated identity containment (session revocation and policy denial), automated credential remediation (key rotation in secrets manager), and concludes with stakeholder notification and incident documentation.
The standard SOAR playbook lifecycle dictates that alerts must first be enriched with contextual log data. Once scope is established, automated containment actions (revoking sessions and denying API actions) are applied to stop active exposure. Following successful isolation, remediation actions rotate credentials in secret stores, and finally, notification tasks update human analysts and close the automated ticket workflow.

Adım Adım Çözüm

1
Perform initial ingestion and automated context enrichment.
Alert data is parsed and CloudTrail/audit logs are collected to quantify the scope of use of the leaked API key.
Enrichment provides necessary context on key usage before modifying permissions or terminating sessions.
2
Execute identity containment controls.
Active sessions created using the key are revoked and an inline explicit deny policy is bound to the identity.
Containment limits damage by ensuring an attacker cannot continue making authorized API calls.
3
Perform secret rotation and remediation.
A new API key pair is generated and securely injected into the enterprise secrets management vault.
Automated remediation restores operational functionality safely with fresh, secure credentials.
4
Notify stakeholders and close the automation workflow.
The application owner receives summary metrics and audit logs for final verification.
Documentation and communication complete the incident lifecycle within the SOAR framework.
