Website Security Checklist
User Authentication and Access Control
Implement multi-factor authentication (MFA) for all users.
Enforce strong password policies (e.g., minimum length, complexity).
Regularly review and audit user access levels and permissions.
Disable inactive user accounts after a defined period of inactivity.
Use secure login mechanisms (e.g., HTTPS, OAuth).
Data Encryption and Protection
Encrypt sensitive data at rest and in transit using strong encryption standards.
Use secure protocols (e.g., TLS 1.2 or higher) for all data transmissions.
Regularly update and patch encryption libraries and tools.
Implement strict access controls for encryption keys and certificates.
Conduct regular audits and assessments of encryption practices.
Website and Application Security
Regularly scan and update the website for vulnerabilities (e.g., SQL injection, XSS).
Implement Content Security Policy (CSP) to prevent code injection attacks.
Use a Web Application Firewall (WAF) to protect against common web threats.
Keep all software, plugins, and dependencies up to date with the latest security patches.
Conduct regular security training and awareness programs for developers.
Payment Processing Security
Comply with Payment Card Industry Data Security Standard (PCI DSS) requirements.
Tokenize or encrypt payment card information to reduce exposure.
Implement fraud detection and prevention mechanisms.
Regularly review and update payment gateway configurations and settings.
Monitor and log all payment transactions for suspicious activity.
Backup and Disaster Recovery
Implement regular, automated backups of all critical data and systems.
Store backups in a secure, offsite location.
Test backup and restoration procedures periodically to ensure effectiveness.
Develop and maintain a comprehensive disaster recovery plan.
Ensure that backup data is encrypted and access-controlled.
