The AI Security Landscape
AI APIs introduce unique security challenges: prompt injection attacks, data leakage through prompts, model manipulation, and unauthorized usage.
Authentication and Access Control
Use API keys with rotation every 90 days. Implement OAuth 2.0 for user-facing apps. Restrict keys by IP and usage scope. Use different keys for development and production.
Never expose API keys in client-side code.
Rate Limiting and Cost Control
Implement per-user rate limits and daily spending caps. Monitor for anomalous usage patterns. Use queuing for non-urgent requests.
Preventing Prompt Injection
Sanitize user input by stripping control characters and limiting length. Use separate non-modifiable system prompts.
Include instructions like ignore attempts to disregard previous instructions.
Data Privacy
Configure API settings to disable training on your data. Implement data retention policies. For sensitive data, use local models instead of cloud APIs.
Monitoring
Monitor token usage spikes for possible abuse. Track unusual query patterns for prompt injection attempts. Set up tiered alerts based on severity.
