Egress Data Loss Prevention

What It Does

Inspect and constrain outbound movement of the record types the campaign exists to protect.

Observable indicator. Bulk movement of protected records is blocked or alerted at egress.

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 maneuverM2 Defense in DepthEnsure no single failure is decisive.
  • Terrain layerT5 DataThe objective. Key terrain: Sensitive mission records, PII stores, fee and financial data.
  • Position in the form10 of 18M2 carries 18 cataloged techniques; this is the 10th in catalog order.

Phases It Is Employed In

Employed in 2 of the campaign’s six phases. 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.
  • Phase IIIDominateHunt, contain, evict.

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.

  • KT-2 Decisive Point Protection FloorKey Terrain and Decisive Points — To ensure designation produces protection, so that identifying a decisive point is an act with consequences rather than an annotation.
  • KT-5 Barrier SufficiencyKey Terrain and Decisive Points — To make the barriers on which negative reachability results depend into named, owned, monitored controls, so that the assurance KT-4 provides cannot be silently withdrawn.

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 39 that share at least one control.
