Implement comprehensive security testing for attack surface validation
- Created 12 comprehensive security tests covering major attack vectors:
* SQL injection protection across all input fields
* XSS protection with payload sanitization validation
* Large payload DoS protection and resource limits
* JSON bomb and malformed input protection
* Path traversal attack prevention
* HTTP method security and protocol validation
* Information disclosure prevention in error responses
* Input validation and sanitization for malicious content
* Rate limiting and abuse protection mechanisms
* Content-Type validation and injection prevention
* Unicode security issues and normalization attacks
* Server information leakage prevention
- Validates security measures including:
* Safe handling of malicious SQL injection payloads as literal text
* XSS payload storage without execution, proper JSON responses
* Graceful degradation under large payload attacks
* Protection against deeply nested JSON and JSON bombs
* Proper 404/400 responses for path traversal attempts
* Disabled dangerous HTTP methods (TRACE, CONNECT)
* Error messages without sensitive information leakage
* Unicode attack vector mitigation and safe storage
* Server header security and implementation details hiding
- All 12 security tests pass demonstrating robust attack surface protection
- System safely handles malicious inputs without compromise
- Proper security boundaries maintained across all attack vectors
