Web applications must be designed with strong security controls to protect user data and prevent cyber attacks.
Authentication and access control
- Implement secure login and registration flows.
- Use role-based access control to restrict sensitive features.
- Enforce strong password policies and secure password hashing.
- Enable multi-factor authentication for critical accounts.
Protection against common attacks
- Validate and sanitize all user inputs.
- Protect forms and APIs using CSRF tokens.
- Prevent SQL injection by using prepared statements or ORM layers.
- Implement Content Security Policy to reduce XSS risks.
Secure communication and headers
- Enforce HTTPS for all application traffic.
- Use secure headers such as HSTS and X-Content-Type-Options.
- Restrict third-party scripts and external resources.
Maintenance and monitoring
- Keep framework and dependencies up to date.
- Monitor logs for suspicious activities.
- Perform regular security audits and penetration testing.
