Triage and analysis

Investigating New Okta Identity Provider (IdP) Added by Admin

This rule detects the creation of a new Identity Provider (IdP) by a Super Administrator or Organization Administrator within Okta.

Possible investigation steps:

  • Identify the actor associated with the IdP creation by examining the okta.actor.id, okta.actor.type, okta.actor.alternate_id, and okta.actor.display_name fields.
  • Identify the IdP added by reviewing the okta.target field and determing if this IdP is authorized.
  • Determine the client used by the actor. Review the okta.client.ip, okta.client.user_agent.raw_user_agent, okta.client.zone, okta.client.device, and okta.client.id fields.
  • If the client is a device, check the okta.device.id, okta.device.name, okta.device.os_platform, okta.device.os_version, and okta.device.managed fields.
  • Review the past activities of the actor involved in this action by checking their previous actions logged in the okta.target field.
  • Examine the okta.request.ip_chain field to potentially determine if the actor used a proxy or VPN to perform this action.
  • Evaluate the actions that happened just before and after this event in the okta.event_type field to help understand the full context of the activity.

False positive analysis:

  • It might be a false positive if the action was part of a planned activity or performed by an authorized person.
  • Several unsuccessful attempts prior to this success, may indicate an adversary attempting to add an unauthorized IdP multiple times.

Response and remediation:

  • If the IdP is unauthorized, deactivate it immediately via the Okta console.
  • If the IdP is authorized, ensure that the actor who created it is authorized to do so.
  • If the actor is unauthorized, deactivate their account via the Okta console.
  • If the actor is authorized, ensure that the actor’s account is not compromised.
  • Reset the user’s password and enforce MFA re-enrollment, if applicable.
  • Block the IP address or device used in the attempts if they appear suspicious, using the data from the okta.client.ip and okta.device.id fields.
  • Conduct a review of Okta policies and ensure they are in accordance with security best practices.
  • If the deactivated IdP was crucial to the organization, consider adding a new IdP and removing the unauthorized IdP.
