Implement Critical Security Measures for Faucet Protection

Security Enhancements for Faucet Protection

Current State

The faucet currently lacks several critical security measures that could make it vulnerable to abuse and attacks. These vulnerabilities could potentially allow malicious users to exploit the faucet system.

Security Issues

1. Rate Limiting

Currently, there is no implementation of rate limiting, which exposes the following risks:

• Users can make unlimited requests to the faucet endpoint
• No cooldown period between requests
• No tracking of requests per wallet address or IP
• Potential for automated scripts to drain the faucet

2. CSRF Protection

The API endpoints are vulnerable to Cross-Site Request Forgery (CSRF) attacks:

• No CSRF tokens implemented in API requests
• POST requests lack security headers
• No protection against cross-site request attacks

3. Input Validation & Sanitization

Current implementation lacks robust input validation:

• No thorough validation of Ethereum addresses
• Basic email validation using only HTML5 type="email"
• Missing sanitization of user inputs before processing

Proposed Solutions

Rate Limiting Implementation

• Add IP-based rate limiting
• Implement wallet address-based rate limiting
• Set appropriate cooldown periods between requests
• Track and store request history
• Add clear user feedback for rate limit status

CSRF Protection

• Implement CSRF token generation and validation
• Add security headers to all API requests
• Set up proper CORS configuration
• Implement token validation middleware

Input Validation

• Add comprehensive Ethereum address validation
• Implement robust email validation
• Add input sanitization for all user inputs
• Implement proper error handling and user feedback

Additional Security Measures

1. Request Throttling

   • Add exponential backoff for failed requests
   • Implement CAPTCHA/reCAPTCHA verification

2. Logging & Monitoring

   • Add security event logging
   • Implement suspicious activity monitoring
   • Track and analyze request patterns

3. Security Headers

   • Implement Content-Security-Policy
   • Set up proper CORS headers
   • Add other relevant security headers

Technical Requirements

• Backend rate limiting system
• Token-based CSRF protection
• Input validation library
• Logging and monitoring system
• CAPTCHA integration

Expected Outcomes

• Protected faucet system against abuse
• Reduced risk of automated attacks
• Better user experience with clear feedback
• Improved system monitoring and security tracking
