Where It Sits in the Scheme

3 ASOM-Fed techniques reach this countermeasure, across 2 forms of maneuver.

This is the direction the forward mapping cannot answer. A reader who works in D3FEND arrives holding D3-DTP and needs to know where it is employed in a scheme of maneuver — not which of MITRE's tactics it belongs to, which they already know.

Reached By

• M3.13 Federation Trust Boundary ControlM3 Envelopment · T1 Identity

  Enumerate every federated trust into the estate, own each one, and constrain what it may assert.

• M3.20 Supplier Identity FederationM3 Envelopment · T9 Supply Chain

  Bring supplier access under the agency's own identity plane rather than standing local accounts the agency cannot see or revoke.

• M8.05 Federation Trust SuspensionM8 Isolation / Retrograde · T1 Identity

  Suspend an inbound federated trust independently, without dismantling the identity plane around it.

Forms That Arrive Here

A countermeasure reached from more than one form is employed more than one way. D3FEND has no notion of a form, so this join exists only here.

• M3 EnvelopmentThe formMake identity, not network location, the decisive plane — surround the adversary with policy.
• M8 Isolation / RetrogradeThe formGive ground deliberately to preserve the force. Degrade gracefully; never fail open.

What This Does Not Claim

That a technique reaches a D3FEND countermeasure says the two describe the same defensive act. It does not say the countermeasure is deployed, configured, or working — that is an assessment finding about your estate, not a property of the framework.

MITRE's own entry for this technique is at d3fend.mitre.org, and it is the authority on what the countermeasure is. This page is the authority only on where it sits in ASOM-Fed.
