🔒 Security: Smart Contract Audit and Security Hardening #2
Description
Summary
Conduct comprehensive security audit and implement security hardening measures for all smart contracts and API endpoints.
Problem Statement
- Smart contracts handling user funds need thorough security review
- API endpoints may be vulnerable to common attacks
- No formal security testing procedures in place
- Missing security monitoring and alerting
- Potential vulnerabilities in external integrations
Security Areas to Address
Smart Contract Security
- Reentrancy Protection: Implement ReentrancyGuard patterns
- Access Control: Proper role-based permissions
- Integer Overflow/Underflow: SafeMath implementations
- Flash Loan Attacks: Protection mechanisms
- Oracle Manipulation: Secure price feed validation
API Security
- Authentication: JWT token validation
- Authorization: Role-based access control
- Input Validation: Sanitize all user inputs
- Rate Limiting: Prevent DDoS attacks
- CORS Configuration: Secure cross-origin requests
Infrastructure Security
- Database Security: Encrypted connections, parameterized queries
- Network Security: Firewall rules, VPN access
- Secrets Management: Secure key storage
- Monitoring: Real-time security alerts
- Backup Security: Encrypted backups
