Dear Valued Customer,

To help maintain a secure and reliable hosting environment, we recommend reviewing and implementing the following security best practices on your VPS. These measures can significantly reduce the risk of unauthorized access, malware infections, spam activity, brute-force attacks, and future abuse reports.

Windows VPS Security Recommendations

  • Use strong, unique passwords for all user accounts, especially the Administrator account.

  • Change the default Remote Desktop (RDP) port (3389) to a custom port whenever possible.

  • Restrict RDP access to trusted IP addresses only.

  • Keep Windows Server and all installed applications updated with the latest security patches.

  • Enable Windows Defender Firewall and allow only the ports required for your services.

  • Install and regularly update a trusted antivirus or endpoint protection solution.

  • Disable unnecessary services and uninstall software that is no longer required.

  • Enable account lockout policies to help prevent brute-force login attempts.

  • Regularly review Windows Event Viewer for failed login attempts and suspicious activities.

  • Perform regular backups and periodically verify that they can be restored successfully.

Linux VPS Security Recommendations

  • Keep the operating system and installed packages updated with the latest security patches.

  • Disable direct root SSH login and use a standard user account with sudo privileges.

  • Use SSH key authentication instead of password-based authentication whenever possible.

  • Change the default SSH port and restrict SSH access to trusted IP addresses.

  • Configure a firewall (UFW, Firewalld, or iptables) to allow only the required ports.

  • Install Fail2Ban or a similar solution to automatically block repeated failed login attempts.

  • Remove unnecessary packages and disable unused services.

  • Regularly review authentication logs and monitor running processes for suspicious activity.

  • Keep all web applications, CMS platforms, plugins, and themes up to date.

  • Periodically scan your server for malware using trusted security tools.

  • Maintain regular backups and test restoration procedures.

  • Use strong and unique passwords for all accounts and services.

  • Remove unused user accounts and unnecessary services.

  • Install software only from trusted and verified sources.

  • Regularly monitor server logs and resource usage.

  • Use secure file transfer methods such as SFTP and avoid insecure protocols whenever possible.

  • Review scheduled tasks (Cron Jobs or Windows Task Scheduler) for any unauthorized entries.

  • Monitor outbound email activity to detect spam or abuse.

  • Enable Multi-Factor Authentication (MFA) wherever supported.

  • Keep all third-party applications and hosting control panels updated.

Why This Matters
