- Conduct security audits and code reviews focusing on input handling and output generation in custom Drupal modules or themes.
- Educate users and administrators about phishing risks and encourage cautious behavior regarding unsolicited links or content.
- Monitor web application logs for unusual activity that could indicate exploitation attempts.
- Utilize web application firewalls (WAFs) with rules targeting XSS attack patterns to provide an additional layer of defense.
- Regularly update Drupal core and contributed modules to incorporate security patches promptly.
