Executing a test is not proof of effective detection.

Start with a precise question

Before an emulation exercise, define the objective in writing. Should execution be prevented? Should a specific action appear in logs? Or should a responsible team receive an actionable alert? One green status indicator cannot answer all of these questions.

Adversary behaviour as a reference

MITRE describes emulation plans for examining selected adversary behaviour and connected techniques. These plans inherit limitations from available reports. An ATT&CK reference helps describe scope; it does not establish that every associated technique was executed or detected.

Four distinct evidence points

We suggest recording four separate observations: execution of the agreed test, a security control response, capture of the relevant event and delivery of an actionable alert. Record time, system, expected result and observed evidence. Missing telemetry means unresolved, not automatically undetected.

How this differs from penetration testing

A penetration test can establish exploitability without examining the entire detection chain. Security control validation focuses on control effectiveness. The methods can complement each other; additional objectives, access and measurement points need to be included explicitly in the engagement.

What to ask for

Ask for the scenario, expected response, measurement point and limitations to be documented together. A retest should answer the same question under comparable conditions. This turns a test run into a decision about the control or process that needs improvement.
