title: Okta admin function access via proxy (requestUri contains admin and isProxy enabled)
id: 46c10404-5e55-41a4-922d-114aa3494891
status: test
description: This rule flags Okta activity where the request URI contains the string "admin" while the request is marked as coming through a proxy. Such access can be used by attackers to reach privileged administrative endpoints while routing traffic through intermediary infrastructure. It relies on Okta telemetry fields for the requested URI and a proxy indicator to identify these events.
