Jailbreak Prevention

Introduction

A jailbreak bypasses model safety to extract harmful content. Prevention combines model alignment, prompt design, and output filtering.

Beginner analogy: Like jailbreaking a phone — bypassing built-in restrictions.

Understanding the topic

Core concepts to understand:

• Common attacks: roleplay ("pretend you are unrestricted"), encoding, multi-step coaxing.
• Defences: explicit refusal rules, output filters, content moderation API.
• Layered defence: prompt + output filter + monitoring.
• Track new jailbreaks in shared databases (OWASP LLM Top 10).

Syntax reference

Visual workflow / architecture:

User input
  ▼ refusal rules + delimiters
  ▼ LLM
  ▼ output moderation (toxicity, hate, etc.)
  ▼ deliver / block / human review

Real-world use

OpenAI, Anthropic, Google all publish jailbreak postmortems; community DBs (LMSYS, OWASP) track new techniques.

Best practices

• Layered defence beats prompt-only.
• Subscribe to OWASP LLM Top 10 updates.
• Red-team prompts before launch.

Hands-on exercise

Interview preparation — practice these questions:

• Q1. What's a jailbreak?
• Q2. Common attack patterns?
• Q3. Layered defence — what layers?
• Q4. Red-teaming process?
