Treat this document as a focused evidence review: Test Defender for Identity cloud connectivity before and after sensor deployment. Only the official source and traced locations below supply facts. Confirm applicability before acting.

\n

Source fact:

\n

The official Test Microsoft Defender for Identity connectivity from Microsoft supports the following bounded statements:

\n\n

Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving Defender for Identity workspaces, sensors, directory-service accounts, action accounts, network paths, roles, and deployment health and the conditions the source actually describes.

\n

What the source does not establish

\n

A successful reachability test does not prove sensor health, event collection, or threat-detection coverage. It does not establish a deployment’s current state, authorize a production change, prove compliance, or show that Active Directory, Windows DNS, time, certificates, domain-controller resources, network capture, cloud connectivity, and security operations are healthy. Documented options are review inputs, not universal mandates.

\n

Applicability questions

\n\n

DSE recommendation:

\n

DSE recommends using the cited source as the evidence anchor for this decision. Use a two-person review for the source interpretation and the resulting operational decision. Record the source location, examined part of Defender for Identity workspaces, sensors, directory-service accounts, action accounts, network paths, roles, and deployment health, observed and expected states, owner, and reason for deviation.

\n

If the review warrants change, use a bounded implementation with prerequisites, test population, monitoring, abort criteria, and a rehearsed reversal. Sequence checks for Active Directory, Windows DNS, time, certificates, domain-controller resources, network capture, cloud connectivity, and security operations and sanitize protected material before retention.

\n

Verification and evidence

\n

Build a reproducible chain from Opening overview; Opening test guidance to the observed environment. Useful domain evidence includes sensor inventory, service and action-account permissions, health alerts, connectivity tests, portal state, and controlled detection tests; label every item with scope, timestamp, collector, and stable identifier.

\n

Preserve both successful and failed observations, along with approval and rollback evidence. Avoid uncontrolled production experiments. Assign an expiry or event-driven recheck so the conclusion is not treated as permanent.
