Physical Locking

Where It Sits in the Scheme

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

This is the direction the forward mapping cannot answer. A reader who works in D3FEND arrives holding D3-EPL 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

• M2.17 Facility Defense in DepthM2 Defense in Depth · T8 Facilities

  Layer physical controls so that defeating one barrier does not deliver the floor, the rack or the media inside it.

• M4.15 Physical Zone SegregationM4 Obstacle / Canalization · T8 Facilities

  Divide facilities into zones whose boundaries are enforced and logged, so physical movement is as canalised as network movement.

• M8.15 Facility IsolationM8 Isolation / Retrograde · T8 Facilities

  Be able to sever a building or floor from the estate without severing the mission, and know in advance what that costs.

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.

• M2 Defense in DepthThe formEnsure no single failure is decisive.
• M4 Obstacle / CanalizationThe formForce the adversary onto ground you own and watch.
• 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.
