As more businesses rely on web hosting to power their websites and online operations, protecting your server environment has never been more critical. If you're using cPanel on your cloud server, implementing security best practices can significantly reduce vulnerabilities and keep your data safe from cyber threats. At SurferCloud, we specialize in high-performance cloud servers, and we've compiled these 15 essential steps to help you strengthen your cPanel server’s security.
Keep Your Server Software Up-to-Date Always update cPanel, Apache, PHP, and other software packages. Outdated versions often contain vulnerabilities that hackers can exploit.
Use Strong Password Policies Ensure users create strong, complex passwords. Enable cPanel’s built-in password strength enforcement and consider using a password manager.
Install a Firewall (CSF Recommended) Use ConfigServer Security & Firewall (CSF) to manage incoming and outgoing traffic. This helps prevent unauthorized access.
Disable Unused Services and Ports Reduce attack surfaces by turning off services and closing ports that aren't being used. Every open port is a potential entry point.
Enable Two-Factor Authentication (2FA) Adding an extra layer of login security with 2FA can prevent unauthorized access even if a password is compromised.
Scan for Malware Regularly Use tools like ClamAV or ImunifyAV to scan your server and websites for malicious files.
Restrict SSH Access Only allow SSH access to trusted IPs, change the default SSH port, and use key-based authentication instead of passwords.
Use Secure FTP (SFTP) Instead of FTP SFTP encrypts file transfers, protecting sensitive data during uploads and downloads.
Limit Login Attempts Use tools like cPHulk to block IPs after several failed login attempts, deterring brute force attacks.
Disable Shell Access for Untrusted Users Don’t give shell access unless it’s absolutely necessary. Most users won’t need it.
Monitor Logs Actively Review logs regularly via WHM or terminal to detect unusual activities early.
Set Up Automatic Backups Daily or weekly backups can save your data in case of attack or system failure. Store them securely offsite.
Use cPanel Security Advisor This built-in tool provides recommendations for improving server security. Review and act on its suggestions.
Protect Email Services Set up SPF, DKIM, and DMARC to secure your email and prevent spoofing or phishing.
Limit PHP Functions and Set Permissions Correctly Disable potentially dangerous PHP functions and ensure file permissions are configured securely (e.g., 644 for files, 755 for directories).
Q&A Section
Q1: Why is cPanel server security important for cloud hosting? A: Because your server hosts all your data, emails, and customer information. A single vulnerability could compromise everything. With cloud hosting like SurferCloud, a properly secured cPanel server ensures better performance, uptime, and data integrity.
Q2: How often should I check for updates? A: Ideally, weekly. Security patches are released frequently, and installing them promptly minimizes risk.
Q3: Can I secure my server without technical expertise? A: Yes. Many steps, like enabling 2FA or using Security Advisor, are easy to follow in the WHM interface. For advanced tasks, consider hiring a managed service or using a secure cloud provider like SurferCloud.
Q4: Is shared hosting as secure as a cloud server? A: Generally, no. Cloud servers offer isolated environments, dedicated resources, and customizable security settings — all of which are harder to implement in shared hosting.
