How to use this glossary

Every term below is one line, and the term itself links to the page that explains it in full — jump straight there when a page assumes a word you haven't seen yet.

The lab loop

Term	Definition
Objective	The goal you're given for a lab — extract the VIP coupon, say — never a script to follow.
Seed	The secrets and canaries your target mints just for your session; nobody else shares them.
Evidence	The value or artifact you submit to prove you reached the objective.
Band	Your result: objective met, partial, or not met — never a bare pass or fail.
Canary token	A per-session marker planted in a target; grading confirms it was actually returned or triggered, not just typed in.
Semantic judge	The model-graded check used for open-ended objectives that don't reduce to an exact match.

Lab mechanics

Term	Definition
Chat lab	A lab shape where you converse directly with a vulnerable assistant.
Target app	A real web app running in a container, with real sinks to reach.
Sandbox	The isolated environment a target app runs in, fully contained.
Sink	A real backend a target app can reach — a database, mail, a tool, an agent.
Prompt injection	Input crafted to override a model's own instructions (OWASP LLM01) — the most common flaw class.
Jailbreak	Coaxing a model past its safety or policy limits through framing, role-play, or encoding.
Track	An Offensive or Defensive learning track — attacking a flaw, or building the fix that holds.
Path	A guided learning path stringing labs and concept videos into one curriculum.
Difficulty ladder	The Beginner, Intermediate, Advanced, Expert rungs a lab sits on.

Teams and GSCP

Term	Definition
Seat	One licensed slot for an active member; freed immediately when they're removed.
Group	A standing org structure for organizing members — by department, team, or region.
Cohort	A time-boxed class with a start and end date, distinct from a standing group.
Assignment	A learning path pushed to a group or cohort with a due date; every learner still gets a fresh seed.
Licence	A purchased GSCP exam slot a team assigns to one member at a time.
Proctoring	The supervised conditions GSCP is sat under — no multiple choice, graded on captured evidence.
Serial number	The identifier on an earned GSCP credential; anyone can verify it publicly, no account needed.
Proficiency rating	GSCP's overall result scale — Insufficient, Developing, Job-ready, Strong — distinct from the labs' three bands.
