22### Investigating New Okta Identity Provider (IdP) Added by Admin
23
24This rule detects the creation of a new Identity Provider (IdP) by a Super Administrator or Organization Administrator within Okta.
25
26#### Possible investigation steps:
27- 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.
28- Identify the IdP added by reviewing the `okta.target` field and determing if this IdP is authorized.
29- 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.
30- 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.
31- Review the past activities of the actor involved in this action by checking their previous actions logged in the `okta.target` field.
32- Examine the `okta.request.ip_chain` field to potentially determine if the actor used a proxy or VPN to perform this action.
33- 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.
34
35### False positive analysis:
36- It might be a false positive if the action was part of a planned activity or performed by an authorized person.
37- Several unsuccessful attempts prior to this success, may indicate an adversary attempting to add an unauthorized IdP multiple times.
38
39### Response and remediation:
40- If the IdP is unauthorized, deactivate it immediately via the Okta console.
41- If the IdP is authorized, ensure that the actor who created it is authorized to do so.
42- If the actor is unauthorized, deactivate their account via the Okta console.
43- If the actor is authorized, ensure that the actor's account is not compromised.
44- Reset the user's password and enforce MFA re-enrollment, if applicable.
45- 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.
46- Conduct a review of Okta policies and ensure they are in accordance with security best practices.
47- If the deactivated IdP was crucial to the organization, consider adding a new IdP and removing the unauthorized IdP.

49## Setup
50
