Shadow and Forgotten Asset Discovery

What It Does

Reconcile discovered internet-facing assets against the authoritative inventory and drive the difference to zero.

Observable indicator. The unreconciled-asset count trends to zero and stays there.

Where It Sits

A technique is chosen from inside a form and emplaced on one layer. Both are the catalog’s own declarations; the position is counted in catalog order.

  • Form of maneuverM1 Screen / GuardGain early warning and buy reaction time before the adversary touches key terrain.
  • Terrain layerT3 NetworksThe corridors. Key terrain: TIC 3.0 access points, segment boundaries, cloud VPC peering.
  • Position in the form2 of 15M1 carries 15 cataloged techniques; this is the 2nd in catalog order.

Phases It Is Employed In

Employed in one phase of the campaign. A phase named here means at least this technique is live in it — not that the form it belongs to is the main effort.

  • Phase 0ShapeContinuous terrain preparation, zero-trust hardening, partnerships, threat intelligence.

Controls That Assess It

The controls the catalog names against this technique. They are what an assessor would test to establish that it is emplaced and working — the indicator above is what shows it is working, which is a different question.

  • TM-1 Terrain Inventory and OverlayTerrain Management — To establish one authoritative positional picture of the estate, so that every later judgment about priority, reachability and risk is made against the same ground.
  • TM-6 Terrain CurrencyTerrain Management — To keep the overlay current against both the clock and the change, so that planning is conducted against ground as it currently is.
  • TM-7 Terrain OwnershipTerrain Management — To attach every element to a person who can be asked to act, so that findings convert into work rather than accumulating.
  • FO-3 Tenancy and Inheritance BoundaryFederal Obligations — To ensure that the customer half of a shared responsibility model is owned by someone, so that inherited controls do not become nobody's job.
  • DV-1 Device Terrain IdentificationDevices Terrain — To make devices positional, so that the crossings into the estate are known and can be defended rather than merely counted.

In MITRE D3FEND

What this technique is called in MITRE’s countermeasure ontology. The join runs technique-to-technique: D3FEND catalogs countermeasures, and the thing with a countermeasure’s shape here is the technique, not the control.

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.

Related Techniques

The catalog declares no relation for this entry, and no other entry names it — the inverse is derived here, so an incoming edge would show up even though this one never declared it. The techniques below share its assessment surface, which is the nearest adjacency the data supports.

Assessed Alongside

Not a declared relation: these are the techniques whose assessing controls overlap this one’s, ranked by how much of the two assessment surfaces coincide. Showing 6 of 14 that share at least one control.
