Triage and analysis

Investigating Attempt to Deactivate an Okta Application

This rule detects attempts to deactivate an Okta application. Unauthorized deactivation could lead to disruption of services and pose a significant risk to the organization.

Possible investigation steps:

  • Identify the actor associated with the deactivation attempt by examining the okta.actor.id, okta.actor.type, okta.actor.alternate_id, and okta.actor.display_name fields.
  • 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.
  • Understand the context of the event from the okta.debug_context.debug_data and okta.authentication_context fields.
  • Check the okta.outcome.result and okta.outcome.reason fields to see if the attempt was successful or failed.
  • Review the past activities of the actor involved in this action by checking their previous actions logged in the okta.target field.
  • Analyze the okta.transaction.id and okta.transaction.type fields to understand the context of the transaction.
  • 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, performed by an authorized person, or if the okta.outcome.result field shows a failure.
  • An unsuccessful attempt might also indicate an authorized user having trouble rather than a malicious activity.

Response and remediation:

  • If unauthorized deactivation attempts are confirmed, initiate the incident response process.
  • 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.
  • Reset the user’s password and enforce MFA re-enrollment, if applicable.
  • Conduct a review of Okta policies and ensure they are in accordance with security best practices.
  • If the deactivated application was crucial for business operations, coordinate with the relevant team to reactivate it and minimize the impact.
