Security System Demo

This example demonstrates the complete input sanitization and prompt injection prevention system for enterprise RAG applications, including threat detection, incident response, and user education.

Overview

The security system demo showcases:

Input Sanitization - Clean and validate user inputs
Prompt Injection Prevention - Detect and block injection attempts
Threat Detection - Identify various types of security threats
Incident Response - Automated response to security incidents
User Education - Educate users about security best practices
Security Monitoring - Real-time security dashboard

Prerequisites

RecoAgent installed and configured
Security packages available
Basic understanding of security threats
Python 3.8+ with required dependencies

Basic Setup

    InputSanitizationSystem, ThreatLevel, InjectionType
)
from packages.rag.security_dashboard import SecurityDashboard, IncidentResponseSystem
from packages.rag.user_education import UserEducationSystem, ViolationType
from packages.rag.security_optimization_guide import SecurityOptimizationGuide

Best Practices

1. Threat Detection

Use multiple detection methods
Regularly update threat patterns
Monitor false positive rates
Implement adaptive thresholds

2. Input Sanitization

Always sanitize user inputs
Preserve functionality while removing threats
Log all sanitization actions
Test sanitization thoroughly

3. Incident Response

Define clear response procedures
Automate where possible
Maintain audit trails
Regular response testing

4. User Education

Provide clear, actionable guidance
Use positive reinforcement
Track education effectiveness
Regular content updates

Troubleshooting

Common Issues

High False Positive Rate

# Adjust detection thresholds
security_config = {
    'prompt_injection': {
        'block_threshold': 0.9,  # Increase threshold
        'sensitivity': 'medium'  # Reduce sensitivity
    }
}

Performance Impact

# Enable caching and optimization
optimization_config = {
    'enable_caching': True,
    'cache_ttl': 3600,
    'batch_processing': True
}

User Complaints

# Improve user education
education_config = {
    'provide_examples': True,
    'explain_decisions': True,
    'offer_alternatives': True
}
