AI Security Best Practices for Business

Data Protection Fundamentals

• Never send sensitive PII to AI models without anonymization
• Understand where AI providers store and process data
• Use enterprise versions with data privacy agreements
• Implement data classification before AI integration
• Regular audits of what data flows to AI systems

Prompt Injection Prevention

• Validate and sanitize all user inputs before AI processing
• Use system prompts that establish clear boundaries
• Implement output filtering for sensitive information
• Test for prompt injection vulnerabilities regularly
• Keep AI prompts separate from user-controlled content

Access Control & Authentication

• Role-based access to AI tools and outputs
• Audit logging for all AI interactions
• API key rotation and secure storage
• Multi-factor authentication for admin access
• Principle of least privilege for AI system access

Vendor Security Assessment

• SOC 2 Type II certification required for enterprise use
• Review data processing agreements and DPAs
• Understand model training data practices
• Evaluate incident response procedures
• Verify geographic data residency compliance

AI-Specific Risks to Monitor

• Hallucination: AI confidently stating false information
• Data leakage: Sensitive info appearing in outputs
• Model manipulation: Adversarial inputs causing errors
• Over-reliance: Teams trusting AI without verification
• Bias amplification: AI perpetuating existing biases
