Securing your Virtual Private Server (VPS) is a must. There are many hackers out there trying to get into servers to obtain sensitive information. A server is only good when it’s secure, and it’s up to you to ensure that your server is properly secured.

Here are some tips:

Update Your Software

Using an older software version makes VPS more vulnerable to security attacks. That’s why make it a habit to ensure that your software is always up-to-date. Doing regular checks is an effective way to stay on top of the necessary updates.

Customize Your SSH Login

It’s common for VPS users to use SSH or Secure Shell to log in to their servers. However, there’s a potential risk that may expose you to a virtual attack, when someone tries to log in to your SSH. To prevent this, you need to change your SSH login to a customized one. Use strong passwords for maximum protection.

Make Regular Backups

Setting up backups and regularly saving backups of the data on your VPS is only right to protect your server. Also, should something go wrong, you can always go back to the earlier version.

Remove Unnecessary Modules

Your Linux distribution likely came bundled with plenty of services and packages. However, not all of them are useful. It’s best to remove the ones that you won’t use.

Keeping services or modules that you don’t use creates a window of opportunity for hackers because it’s probably one of the least monitored ones that are easy to infiltrate. Make sure not to install unnecessary software as well.

Make Sure SSH Configuration Is Secure

SSH always needs to run on the VPS, which makes it a target for hackers. Make it a priority to keep your SSH secure by changing the default port from port 22 and prevent root access for users logging into the server using SSH. Additionally, disabling password-based authentication is better instead of requiring key pairs. It’s also best to limit logins to a specific group of users only.

Be Vigilant

One of the most important things to do to protect your VPS is always to be vigilant. Stay guarded against the possibility of security threats and stay up-to-date on the latest threats circulating online.

Reading resources, checking out forums, and joining social media groups will help you stay on top of security threats that could potentially harm your servers. Knowledge is power, so be proactive and practice vigilance at all times.


These tips to secure your VPS will not take a lot of your time, but it requires a specific level of administrative experience. Keep in mind that server vulnerabilities can be detrimental, hence you need to implement the best practices to keep your server secure. You also have to remember that there’s a huge number of hackers out there that work around the clock to find the slightest security weaknesses in your VPS.
