2. Verify Installation - After upgrading, confirm the version number in the Joomla! administrator panel under System → System Information.
3. Review Database Logs - Examine database and web server logs for suspicious queries or unauthorized access attempts that may indicate prior exploitation.
4. Implement Defense-in-Depth - Apply these additional security measures:
• Use a Web Application Firewall (WAF) to filter malicious SQL injection attempts
• Apply the principle of least privilege to database user accounts
• Enable database query logging for security monitoring
• Regularly review and apply Joomla! security updates
5. Security Assessment - If exploitation is suspected, conduct a comprehensive security audit, reset all user passwords, and review all database content for unauthorized modifications.
