# Adversary Emulation — index & methodology

**Adversary emulation** reproduces a *specific, named* threat actor's tactics,
techniques and procedures (TTPs) — drawn from real, attributed intelligence —
to test whether the target's people, process, and tooling detect and respond
the way they should. It is distinct from generic penetration testing
(opportunistic) and from *simulation* (abstract/random): emulation is
**threat-informed** — every action traces to something a real group has been
documented doing, mapped to [MITRE ATT&CK](https://attack.mitre.org/).

> **Authorized use only.** Emulate an actor's TTPs **only** within the engagement's
> Rules of Engagement and approved scope. Destructive techniques (Impact tactic:
> ransomware, wipers, ICS manipulation) are emulated as *non-destructive proofs*
> (e.g., a benign canary file, a dry-run) unless the RoE explicitly authorizes
