5.7Data Leakage Prevention Checklist

• PII regex scanner runs on every LLM response before returning to user
• System prompt extraction resistance tested with 10+ techniques
• Cross-session isolation verified with concurrent user tests
• Internal URLs and API endpoints filtered from responses
• Database connection strings and credentials filtered
• Production monitoring pipeline deployed for real-time scanning
• Alert configured for any critical-severity data leakage finding
• Weekly report of all data leakage findings generated

Data leakage in AI systems is a continuous monitoring challenge, not a one-time test. Deploy automated scanners in production and review findings regularly.
