# Adversarial Prompting and Security Testing

**Last updated:** 2026-06-19
**Status:** GA
**Category:** Prompt Engineering & LLM Optimization

---

## Introduksjon

Adversarial prompting og security testing omfatter teknikker for å identifisere, teste og mitigere sikkerhetstrusler mot Large Language Models (LLMs) og generative AI-systemer. Dette inkluderer både angrepsmetoder som prompt injection og jailbreaking, samt defensive strategier og automatiserte testverktøy.

Microsoft Azure tilbyr et komplett sett med verktøy for å beskytte AI-systemer mot adversarial attacks:
- **Prompt Shields** (Azure AI Content Safety) — detekterer og blokkerer prompt injection-angrep
- **Azure AI Red Teaming Agent** — automatisert adversarial testing med PyRIT
- **Content Filters** — flerlagret filtrering av inputs og outputs
- **Safety Meta-Prompts** — system-level instruksjoner som styrer modell-oppførsel

**Confidence:** High (GA-features, verifisert mot microsoft.com/learn, januar 2026)

## Beslutningsveiledning

### Når bruke hvilken security control?

| Scenario | Anbefalt Control | Prioritet |
|----------|------------------|-----------|
| **User-facing chatbot** | Prompt Shields + Content Filters | Must-have |
| **RAG application med eksterne dokumenter** | Prompt Shields for Documents (Indirect) | Must-have |
| **Internal copilot (lav risiko)** | Safety Meta-Prompts + Content Filters | Recommended |
| **AI agent med tool access** | Full agentic security stack (Pattern 3) | Must-have |
| **Pre-deployment validation** | Azure AI Red Teaming Agent | Must-have |
| **Compliance-kritisk (GDPR, HIPAA)** | Defense-in-Depth (Pattern 1) | Must-have |
| **Prototype/POC** | Default content filters | Minimum |

### Severity Thresholds for Content Filters

Default policy for Azure OpenAI:

| Risk Category | Input Threshold | Output Threshold |
|---------------|----------------|------------------|
| Hate and Fairness | Medium | Medium |
| Violence | Medium | Medium |
| Sexual | Medium | Medium |
| Self-Harm | Medium | Medium |
| Jailbreak (User Prompt) | Enabled (N/A) | - |
| Protected Material (Text) | - | Enabled (N/A) |
| Protected Material (Code) | - | Enabled (N/A) |

**Severity levels:**
- **Safe** — journalistic, scientific, medical contexts
- **Low** — stereotyping, prejudiced views (ikke filtrert default)
- **Medium** — offensive, mocking, harmful instructions
- **High** — explicit harm, illegal content, radicalization

**Anbefaling for offentlig sektor:** Medium threshold (default) + manual review for High detections.

### Attack Success Rate (ASR) Acceptance Criteria

| System Type | Max ASR | Testing Frequency |
|-------------|---------|-------------------|
| **Production (public-facing)** | < 3% | Pre-deploy + Monthly |
| **Production (internal)** | < 5% | Pre-deploy + Quarterly |
| **Development** | < 10% | Per sprint/release |
| **POC** | < 20% | Pre-production gate |

**Tolkning:**
- ASR < 5% = God sikkerhet, deploy-ready
- ASR 5-10% = Requires remediation (meta-prompts, filters)
- ASR > 10% = Critical issues, block deployment

**Når velge Prompt Shields over custom input validation?**

| Factor | Prompt Shields | Custom Logic |
|--------|---------------|--------------|
| **Coverage** | 4 attack categories (GA) | Må implementeres manuelt |
| **Maintenance** | Microsoft oppdaterer | Team må vedlikeholde |
| **Latency** | ~50-100ms overhead | Varierer |
| **Cost** | $1/1K transactions | Development time |
| **Compliance** | Microsoft-certified | Må auditeres |

**Anbefaling:** Alltid start med Prompt Shields, supplement med custom logic kun hvis spesifikke domene-regler kreves.

**Når velge Azure AI Red Teaming Agent over manual testing?**

| Factor | Automated (Agent) | Manual Red Teaming |
|--------|-------------------|-------------------|
| **Coverage** | 20+ attack strategies | Avhenger av expertise |
| **Consistency** | Reproducible | Varierer per tester |
| **Speed** | 100 attacks på minutter | Dager-uker |
| **Cost** | ~40 NOK/run | 50,000+ NOK/kvartal |
| **Depth** | Defined scenarios | Creative edge cases |

**Anbefaling:** Bruk begge — automated for coverage + consistency, manual for creative edge cases og domain-specific risks.

### Common pitfalls

**Pitfall 1: Kun output filtering**

*Problem:* "Vi setter opp content filters på output, det holder vel?"

*Cosmo:* "Nei — det er for sent. Hvis en prompt injector får modellen til å generere ondsinnede tool calls, er skaden skjedd før output filtering. Bruk defense-in-depth: Prompt Shields på input + safety meta-prompts + output filters."

**Pitfall 2: One-time testing**

*Problem:* "Vi kjørte red teaming før launch, trenger ikke mer testing?"

*Cosmo:* "Models og attack vectors evolves. En gang-testing gir false sense of security. Implementer continuous red teaming (monthly) + real-time monitoring. DORA krever også periodic resilience testing."

**Pitfall 3: Ignorer indirect attacks (XPIA)**

*Problem:* "RAG system med eksterne docs — kun testet user prompts?"

*Cosmo:* "Kritisk gap! Indirect prompt injection via documents er en stor risikoflate. Attackers kan embedde hidden instructions i PDFs, emails, websites. Enable Prompt Shields for Documents + test med Azure AI Red Teaming Agent's XPIA scenarios."

**Pitfall 4: Over-reliance på ASR metric**

*Problem:* "ASR = 2%, vi er sikre?"

*Cosmo:* "ASR er en proxy metric, ikke garanti. Den dekker kjente attack patterns, ikke zero-days. Supplement med:
- Manual red teaming (creative attacks)
- Domain-specific risk scenarios
- Real-world monitoring (Defender for AI)
- Incident response drills"
