This document outlines the security measures implemented in the Universal SQL VMM project.

• JWT Authentication: All API endpoints require a valid JWT token for authentication.
• Role-Based Access Control: Users can be assigned different roles with varying levels of access.
• Token Expiration: JWTs have a configurable expiration time to limit the window of opportunity for token theft.

• SQL Validation: All SQL queries are validated to ensure they meet the required format and structure.
• SQL Injection Prevention: SQL queries are checked for common SQL injection patterns.
• Input Sanitization: All user inputs are sanitized to prevent XSS and other injection attacks.
• Parameter Validation: Request parameters are validated for type, format, and allowed values.

• API Rate Limiting: Limits the number of requests per client to prevent abuse.
• Authentication Rate Limiting: More aggressive rate limiting for authentication endpoints to prevent brute force attacks.
• Configurable Limits: Rate limits can be configured based on endpoint sensitivity.

• Centralized Error Handling: All errors are processed through a central error handler.
• Sanitized Error Messages: Error messages are sanitized to avoid leaking sensitive information.
• Typed Errors: Errors are categorized by type for better handling and reporting.
• Comprehensive Logging: All errors are logged with context for debugging and auditing.

• Encryption: Sensitive data is encrypted using AES-256-CBC.
• Secure Headers: HTTP headers are set to enhance security (using Helmet).
• HTTPS Support: All communications can be encrypted using HTTPS.
• Payload Size Limits: Request body size is limited to prevent DoS attacks.

• Dependency Scanning: Regular scanning of dependencies for vulnerabilities.
• Code Reviews: Security-focused code reviews for all changes.
• Security Testing: Automated security tests as part of the CI/CD pipeline.
• Regular Updates: Dependencies are regularly updated to patch security vulnerabilities.

• Request Logging: All requests are logged for auditing purposes.
• Error Monitoring: Errors are monitored and alerted on.
• Access Logging: Authentication and authorization events are logged.
• Performance Monitoring: System performance is monitored to detect anomalies.

1. Use Environment Variables: Store sensitive configuration in environment variables.
2. Implement Network Security: Use firewalls and network segmentation.
3. Regular Backups: Implement regular backups of all data.
4. Security Updates: Keep the host system and all dependencies updated.
5. Principle of Least Privilege: Run the service with minimal required permissions.

• Unit Tests: Test individual security components.
• Integration Tests: Test security measures in combination.
• Penetration Testing: Regular penetration testing to identify vulnerabilities.
• Load Testing: Test the system under load to ensure security measures hold up.
