Zorluk: Çok zorIdentity and Access Management Operations

A security operations center (SOC) detects an active compromise of an administrative account with elevated privileges across hybrid cloud infrastructure. To contain the incident and restore secure identity operations according to privileged access management (PAM) best practices, place the mitigation and lifecycle remediation steps in the correct chronological sequence.

  1. 1Terminate active administrative sessions and invalidate dynamic OAuth/OIDC tokens across the Identity Provider (IdP).
  2. 2Trigger an automated System for Cross-domain Identity Management (SCIM) force-sync to disable the compromised identity across federated SaaS applications.
  3. 3Rotate the credential baseline stored in the Privileged Access Management (PAM) vault for all affected service accounts.
  4. 4Conduct an Identity Governance and Administration (IGA) recertification audit to re-baseline entitlements and verify least privilege enforcement.

Cevap

The correct operational order for containing and remediating a compromised privileged account is: First, terminate active sessions and invalidate tokens at the IdP; second, trigger an automated SCIM push to revoke downstream federated SaaS access; third, rotate vaulted credentials within the PAM solution; fourth, perform an IGA entitlement recertification audit.
In security operations, incident containment prioritizes immediate threat suppression: active session termination and token invalidation at the IdP stop ongoing adversary actions. Once centralized sessions are severed, automated SCIM provisioning pushes account disablement to downstream federated services. Next, secrets stored in the PAM vault are rotated to prevent credential reuse. Finally, IGA recertification cleanses unauthorized entitlement changes made by the threat actor.

Adım Adım Çözüm

1
Perform immediate active session containment
Active adversary connections are terminated and access tokens are invalidated at the centralized Identity Provider.
Containment must occur at the root IdP level before attackers can pivot or establish additional persistence mechanisms.
2
Synchronize account disablement across federated environments
SCIM protocol updates disable state across external Service Providers (SPs).
Relying solely on central IdP disablement without SCIM or continuous access evaluation (CAE) can leave active SaaS sessions functional until refresh tokens expire.
3
Rotate administrative secrets and vault baseline credentials
All static and dynamic passwords, API keys, and certificates associated with the compromised account are refreshed in the PAM vault.
Vault rotation ensures that harvested credentials cannot be reused to re-authenticate after sessions are killed.
4
Execute post-incident Identity Governance and Administration (IGA) recertification
All granted entitlements, group memberships, and role assignments are audited and reconciled against authorization baseline policies.
IGA recertification verifies that persistence mechanisms, such as unauthorized role assignments created during the incident, are completely removed.
