6 Ways to Keep your Linux VPS Secure

When you opt for a Virtual Private Server (VPS) for your hosting needs, you need to make another important decision – if you want to opt for a Linux VPS or Windows VPS. While this decision depends a lot on the requirements of your business and website, security of the site and your data holds paramount importance. While many site owners prefer Linux VPS Hosting as it offers better security due to the Linux Security model (LSM), it has its own share of vulnerabilities too. In this article, we will offer six tips to help you keep your Linux VPS secure.

#1. Deny permissions to log in to the VPS using the username ‘root’

When you buy a Linux VPS, the provider usually offers an account to allow complete root access. This account typically has the username ‘root’ and a secure password. However, this gives the hackers an opportunity to try using brute force to gain access to your VPS. By denying all permissions to the username ‘root’ you can add a layer of security. You can create another username (which is not easy to guess) and use the ‘sudo’ command to access the root.

#2. Change the default SSH Port

Another default setting provided by hosting providers is the SSH port number – 22. Most hackers are aware of this and try to hack SSH using this port number. By changing the port number, you can prevent viruses and other dangerous scripts from connecting with your VPS. Open /etc/ssh/sshd_config and make the necessary changes.

#3. Updates are your friends

We are talking about server software updates. It is important to remember that these updates are released to ensure that you are working in a secured environment and delaying the updates only exposes you to more threats. You can update the software manually or automate the task. A handy tip – check for updates at least once every week.

#4. A firewall is a must

You cannot have a really secure VPS without a firewall. There are many firewall options when it comes to a Linux VPS. In fact, Netfilter is a firewall which is integrated with the Linux kernel. All you need to do is configure it and make your VPS more secure.

#5. SFTP instead of FTP

The File Transfer Protocol or FTP is a well-known option for moving files between two remote terminals. However, in FTP, the authentication is sent as plain text and hence, can easily be hacked. Therefore, it is important to use a more secure connection – SFTP or SSH FTP which comes free as a part of the SSH suite. It performs the same tasks as the FTP but is more secure.

#6. Backups are your insurance policies

No data is completely secure unless it has a backup. In order to make your VPS secure, ensure that you take regular backups of the entire website. Remember, no matter how many measures you take to secure your VPS, a backup helps you face any disaster efficiently without losing data or customers.

Summing Up

We hope that these tips help you make your Linux VPS more secure so that you can focus on growing your business and offering better services to your customers. Buy the VPS from a good provider who prioritizes security over everything else. Good Luck!
