Major Technical Tips to Secure VPS from DDoS Attacks

These are the major tips you must do right away to protect your VPS server.

  1. Disable Root Logins

Prevent brute-force attacks by disabling logins from the root user. Create alternative usernames with the privilege to execute root-level commands.

  1. Change the Default SSH Port

Modify the default SSH port (22) to access your virtual server. This step helps prevent hackers from efficiently targeting your website.

  1. Start Using SSH Keys

Utilise SSH keys generated by your computer instead of passwords to log in to your SSH account. SSH keys are longer and more complex, enhancing security.

  1. Use SFTP instead of FTP

Secure file transfers using FTP over SSH or SFTP, as FTP connections lack encryption and are susceptible to sniffing attacks.

  1. Set up a VPN for Your VPS

Protect your data while using public connections by establishing a Virtual Private Network (VPN) to mitigate security risks.

Basics Tips to Secure Your VPS Hosting Server from DDoS Attacks

These are the common tips to keep in mind for protecting your VPS server from any DDoS attacks.

  1. Research Your Web Hosting Security

Ensure your hosting provider offers a strong infrastructure and additional server protection, such as advanced security modules like mod_security, firewall, Suhosin PHP hardening, and PHP open_basedir protection.

  1. Use Strong Passwords

Create strong passwords with lowercase and uppercase letters, numbers, and special characters. Avoid using standard information or personal details as passwords to reduce vulnerability to brute-force attacks.

  1. Set Up an Internal Firewall

Establish an internal firewall to filter incoming and outgoing data packets, safeguarding your website from unwanted traffic and DDoS attacks.

  1. Install an Antivirus

Strengthen security of your virtual server by installing antivirus software, which helps detect and eliminate potential threats from your VPS.

  1. Review User Rights and Disable IPv6

Regularly review and manage user rights to prevent unauthorised access. If you’re not actively using IPv6, it’s recommended to disable it to avoid exposing vulnerabilities.

  1. Monitor Server Logs

Keep track of server logs to stay informed about your VPS hosting’s activities and detect any suspicious behaviour or anomalies.

  1. Keep Your Applications Up To Date

Update your website applications regularly, including security patches and plugins, to minimise vulnerabilities and ensure optimal protection against potential attacks. Stay vigilant for the latest versions and promptly install them as they become available.


If you follow the steps mentioned, you can enhance your virtual server more efficiently. It is crucial because if your website data gets hacked, it can be used against your website’s reputation. If you stay protected from DDoS attacks, you can maintain your website more accurately without any issues.
