Defense in Depth
Multiple layers of security to prevent a single point of failure.
Input Sanitization
The first line of defense.
• Strict Typing: Ensure inputs match expected formats.
• Content Filtering: Using secondary LLMs to check for injection patterns.
• Rate Limiting: Preventing automated brute-force prompt attempts.
Monitoring and Observability
Detecting attacks in real-time.
• Anomaly Detection: Monitoring for unusual prompt patterns.
• Output Auditing: Checking for leaked PII or corrupted logic.
• Feedback Loops: Implementing human-in-the-loop for high-risk actions.
The Over-reliance Trap
Do not rely solely on 'system prompts' for security. A determined attacker can bypass almost any static prompt. True security requires external verification layers.
