Ambush

Trade space for information and time, and impose cost.

Intent, Mechanism and Indicator

Trade space for information and time, and impose cost.

Role. The cheapest high-confidence detection available

Mechanism

Honeypots, decoy credentials and documents, honeytokens seeded through the data terrain.

Observable indicator

The adversary interacts with a decoy, producing a detection with no false-positive budget.

Terrain It Consumes

Derived from where the form’s techniques are actually emplaced. The highlighted layer is the one the catalog names as its principal ground — the rest is terrain the form still has to touch, and that spread is how much of the estate employing it implicates.

Campaign Phasing

Dominance is taken from the campaign model; participation is derived from the techniques themselves. A form is usually present in more phases than it leads, and confusing the two is how a scheme ends up with no main effort.

Employment

When to Choose It

Choose ambush when alert fatigue, not sensor coverage, is the binding constraint — when the SOC sees plenty and believes little. Deception produces the one class of detection that needs no tuning: legitimate users have no reason to touch a decoy, so an interaction is contact by construction. It is also the form to choose when you need to buy information rather than deny access, because a decoy that holds an adversary’s attention is collection.

Precondition

An alert path that ends in a human within minutes. A decoy is a detection with no false-positive budget, and routing it into a queue that is triaged tomorrow throws that property away.

What It Costs

Low in money, high in discipline. Decoys must be maintained or they age into obviousness — stale timestamps, empty directories and implausible content are how an experienced adversary identifies the grid and routes around it. Decoy credentials that bind to real staff identities need legal and personnel review before emplacement, not after.

Rules of Engagement

Emplacing and maintaining the grid is standing SOC and terrain-owner work. Anything that engages the adversary beyond observation — feeding them fabricated content, or interacting deliberately — is an influence activity and needs explicit AO authorization and legal review.

How It Fails

Not whether it fails — how. Each of these is a state in which the form is still reported as implemented and has stopped producing the advantage it was chosen for.

  1. The grid is not maintained, so it reads as decoy to the adversary and as coverage to the defender.
  2. A decoy is reachable by a legitimate process — a backup agent, a discovery scanner, an inventory sweep — and the estate’s best detection becomes its noisiest.
  3. Deception is placed where an adversary who has already reached the objective would go, rather than along the path they must traverse. A decoy behind the crown jewels fires after the damage.
  4. Coverage is never measured, so the grid drifts into the layers that were easy to instrument and away from the ones the threat courses of action actually run through.
  5. Decoy hits are routed to the same queue as everything else, which discards the only property that made them worth emplacing.

Techniques (13)

Grouped by the terrain layer each is emplaced on. Techniques are the perishable layer of the framework — they churn, the form does not — so each is stated as what it does and the observable that shows it is working, never as a product.

Controls That Assess It

Derived from the controls the form’s own techniques name, so the assessment surface cannot disagree with the catalog. A control reached by many techniques is load-bearing for this form; one reached by a single technique is not, and an assessor sampling it will learn very little.

By Family

By Control

  • SM-7 Deception Emplacement13 techniquesTo obtain detection with no false-positive budget, and to ensure that signal is acted on rather than queued.
  • CE-2 Priority Intelligence Requirements10 techniquesTo direct analytic effort at named questions, so that collection and hunting answer what the accountable authority needs rather than processing what arrives.
  • KT-4 Adversary Reachability Assessment3 techniquesTo produce a computed, repeatable answer to the question a control catalog cannot ask — can they get there from here — and to record the answer as a trend rather than a one-time finding.
  • CE-3 Fusion and Confidence2 techniquesTo distinguish assessment from assertion, so that decisions taken on analytic conclusions carry the uncertainty of those conclusions with them.
  • TA-1 Decision Loop Measurement2 techniquesTo make the defender's tempo a measured quantity rather than an impression, so that the numerator of temporal advantage exists at all.
  • CE-4 Coverage and Residual Risk Computation1 techniqueTo produce a posture figure that can be reproduced and challenged rather than asserted, so that the number carries authority beyond the tool that generated it.
  • EN-1 Event Declaration and Triage1 techniqueTo convert raw events into a decided position quickly, since this is the segment of the decision loop that most often binds.
  • FC-1 Facility Terrain Identification1 techniqueTo resolve the estate to physical locations, so that defense, recovery and continuity can be reasoned about in the place things actually are.
  • FO-1 Privacy Terrain Identification1 techniqueTo make privacy exposure positional, so that the elements holding personal information can be defended, minimized and accounted for as terrain.
  • FO-4 Operational Technology Terrain1 techniqueTo stop operational technology being scored as though it were a server estate, and to make the connections between the two declarable.
  • ID-2 Credential Strength and Binding1 techniqueTo ensure the credential is as strong as the access behind it, so that proofing and authentication assurance are matched rather than assumed.
  • KT-2 Decisive Point Protection Floor1 techniqueTo ensure designation produces protection, so that identifying a decisive point is an act with consequences rather than an annotation.
  • KT-3 Avenue of Approach Analysis1 techniqueTo convert the estate's connectivity into a set of named approach routes, so that defense can be emplaced on the routes that exist rather than distributed evenly across ground.
  • KT-5 Barrier Sufficiency1 techniqueTo 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.
  • SM-6 Maneuver Effectiveness Validation1 techniqueTo replace assumed effectiveness with demonstrated effectiveness, so the coverage figure reflects what controls do rather than what was assumed of them.
  • TA-4 Pre-authorized Response1 techniqueTo remove authority latency from the decision loop, so that the segment most programs cannot shorten with tooling is shortened by governance.
  • WF-3 Role-Based Readiness1 techniqueTo prepare people for the attacks their role attracts, and to know whether the preparation worked.

The cycle-execution controls test that deception telemetry is collected and routed; the coverage controls test whether the grid maps to the threat courses of action rather than to convenience; the tempo controls test the time from decoy interaction to human decision. Ask when each decoy was last refreshed — the freshness distribution is the honest measure of a deception program.

Sequencing

A scheme names a sequence, not a set. These are the ordinary neighbors of this form — not a mandatory order, but the order in which each one’s preconditions are usually met.

Typically Followed By

  • M7 CounterattackA decoy interaction is the highest-quality hunt trigger the estate produces.
  • M6 DelayTime bought at the decoy is only useful if something slows the adversary down.

Named as a successor by M4 Obstacle / Canalization. Derived from those forms’ own declarations, so the two directions of the sequence cannot disagree.

Named as a predecessor by M6 Delay, M7 Counterattack. Derived the same way, from the other direction.
