Protecting Against Web Defacement

Back to Best Practices

Protecting Against Web Defacement

Web Application & Server Security

Regularly update and patch CMS platforms, plugins, and web servers to fix known vulnerabilities.
Disable or remove unused CMS features, themes, and plugins to minimize attack surfaces.
Deploy a Web Application Firewall (WAF) to block malicious traffic and common web attacks.
Enforce a Content Security Policy (CSP) to prevent unauthorized script execution.

Access Control & Authentication

Implement Multi-Factor Authentication (MFA) for all administrative and privileged accounts.
Restrict access to website administration panels using IP allowlisting or VPN-based access.
Enforce strong, unique passwords and prevent password reuse across different services.

Secure Web Development Practices

Apply input validation and sanitization to prevent SQL Injection (SQLi) and Cross-Site Scripting (XSS).
Follow the Principle of Least Privilege (PoLP) for database and website user accounts.
Restrict file uploads to trusted formats and scan them for malware before processing.

Network & Server Hardening

Configure intrusion detection and prevention systems (IDS/IPS) to monitor and block suspicious activity.
Set correct file and directory permissions to prevent unauthorized modifications.
Disable directory listing to prevent attackers from discovering sensitive files.

Backup & Recovery

Maintain regular backups of website files and databases, stored securely and offline.
Automate backup integrity testing to ensure quick restoration.

Monitoring & Detection

Deploy File Integrity Monitoring (FIM) to detect unauthorized modifications.
Implement real-time website monitoring to detect and alert on unexpected changes.
Utilize CDNs with DDoS protection to mitigate attacks that may lead to defacement.
