Prompt Injection & Defense: Enterprise Guide

What is Prompt Injection?

Prompt injection is an attack where malicious input manipulates the behavior of an AI system. It's one of the most critical security challenges for LLM-based systems.

Attack Vectors

• Direct injection through user input
• Indirect injection through external data sources
• Second-order injection attacks

Defense Mechanisms

• Input validation and sanitization
• Prompt engineering best practices
• Output validation
• System prompts and guardrails

Best Practices

This guide provides practical defense strategies and implementation patterns for organizations using LLMs in production.
