"""
|
|
Unified Kill Chain phase vocabulary (Pols, 2017).
|
|
|
|
Used as the canonical phase enum for campaign clustering and (eventually)
|
|
the MITRE ATT&CK / TTPs-tagging worker. UKC tactic names map cleanly onto
|
|
ATT&CK tactics, so emitting these labels in synthetic data and runtime
|
|
phase inference avoids a renaming pass when TTP-tagging lands.
|
|
|
|
A honeypot does not observe the entire chain. Pre-target phases (OSINT
|
|
reconnaissance, resource development, weaponization, social engineering)
|
|
happen before any decky is touched. The DSL allows the full enum so a
|
|
campaign spec can describe an end-to-end story; the synthetic generator
|
|
emits no events for unobservable phases.
