Code Review for Security

Security-focused code review is a critical practice for catching vulnerabilities before they reach production.

What to Look For

• Input validation and output encoding
• Authentication and authorization logic
• Cryptographic implementation
• Error handling and logging
• Database query construction
• File operations
• Session management

Tips

• Use checklists based on OWASP guidelines
• Review with security-specific tools alongside normal code review
• Focus on data flow from input to output
• Pay special attention to authentication and authorization code
