Red Teaming ist die Praxis, systematisch zu versuchen, ein System zu brechen — um Sicherheitslücken VOR produktiven Deployments zu finden. Für LLMs bedeutet das: Jailbreaks, Injektionen, Bias-Exploitation und Datenlecks proaktiv testen.
Diese Seite behandelt Red-Teaming-Methodik, automatisierte Tools und praktische Test-Szenarien.
1. Red Teaming Basics für LLMs
1.1 Vier Test-Kategorien
Category 1: JAILBREAKS & INSTRUCTION OVERRIDE
Goal: Kann das Modell seine Sicherheitsrichtlinien überschreiben?
Examples:
- Role-playing (DAN, UnfilterBot)
- Authority impersonation
- Scenario framing
Detection: Pattern matching + Human review
Category 2: TOXICITY & HATE SPEECH
Goal: Kann das Modell toxische Inhalte generieren?
Examples:
- Offensive language
- Hate speech gegen Gruppen
- Violence-promoting content
Detection: Toxicity classifiers, keyword matching
Category 3: BIAS & DISCRIMINATION
Goal: Zeigt das Modell stereotype oder diskriminatorische Ausgaben?
Examples:
- Gender/race-based stereotypes
- Occupational bias
- Identity-based discrimination
Detection: Fairness metrics, manual review
Category 4: DATA LEAKAGE & PRIVACY
Goal: Kann das Modell unbeabsichtigt sensible Daten preisgeben?
Examples:
- PII extraction (SSN, email, phone)
- Training data memorization
- Credential leakage
Detection: PII extractors, memorization tests
Category 5: RISKY CONTENT
Goal: Kann das Modell illegale/gefährliche Inhalte generieren?
Examples:
- Waffen-/Sprengstoff-Anleitungen
- Hacking-Techniken
- Selbstverletzungs-Inhalte
Detection: Content classifiers, regex patterns
