So, you just purchased a super reliable and affordable VPS<\/a><\/strong> from SSD Nodes, and you're now ready to deploy your applications or install self-hosted<\/a> software. But wait, you need to put first things first, and you must secure your VPS. This guide will walk you through exactly that! I will show you all of the essential steps you must take for strong VPS security.<\/p>\n

Why You Should Secure Your VPS Server<\/h2>\n

VPS Security gives back exactly what you put into it.<\/p>\n

No matter how small or big the project you\u2019re running on your VPS is, you need to be vigilant. Attackers are continually probing the entire internet for servers that they can easily commandeer, whether that\u2019s through misconfigured SSH, weak passwords, or security bugs in server-side software. Attackers look for easy targets, move quick, and leave a lot of damage in their wake.<\/p>\n

How to Secure Your VPS Servers<\/h2>\n

The goal of this guide is to give you easy-to-follow, high-value strategies for protecting your server. You should follow these steps when you first create an account with your VPS hosting provider and whenever you provision a new server. These tips will work on most VPS-hosted servers running one of the popular variants of Linux, such as Debian,Ubuntu, Fedora, or RockyLinux.<\/p>\n

Note:<\/strong> This guide is just the start of server security, but by following these steps, you'll avoid being an easy target, which is a crucial first step. For a more in-depth guide, check out Red Hat\u2019s security guidebook<\/a>.<\/p>\n

Step 1) Perform Regular Security Updates<\/h2>\n

No matter what OS, software, and services you\u2019re using on your new server, you want to ensure that they\u2019re always up-to-date. The developers behind Linux distributions (Ubuntu, Debian, CentOS, and so on) are constantly updating software to patch and mitigate security issues. Not upgrading regularly can leave your server vulnerable to known, exploitable flaws. Luckily, most Linux distributions (and all those available through SSD Nodes) come with a package manager that makes updates incredibly easy.<\/p>\n

\"VPS<\/p>\n

Ubuntu\/Debian<\/h3>\n

For Ubuntu\/Debian, the updating process uses a tool called apt<\/code>.<\/p>\n

sudo apt update\r\nsudo apt upgrade<\/code><\/pre>\n
The first command updates the list of available software, and the second downloads and installs any new updates for software you currently have installed.<\/p>\n
Rocky Linux\/AlmaLinux\/CentOS\/RHEL<\/h3>\n
For Rocky Linux, AlmaLinux, CentOS, and RHEL, the updating process uses a tool called dnf<\/code>.<\/p>\n
sudo dnf check-update\r\n\r\nsudo dnf upgrade<\/code><\/pre>\n
The first command checks for updates and the second updates the list of available packages and installs any new updates for the software currently installed.<\/p>\n
Avoid Installations With Deb\/Rpm<\/h3>\n
It can be tempting to use the tools behind these package management systems such as deb<\/code> and rpm<\/code> to install external packages. At SSD Nodes, we recommend against this practice, namely because it creates dependency issues if you aren\u2019t fully aware of the consequences of installing a certain package.<\/p>\n
As a rule of thumb, only install software with the appropriate package manager for your system: apt<\/code> or dnf<\/code>.<\/p>\n
If you must install software not in the package manager, you can use developer-created repositories like Ubuntu's PPAs, which integrate with the system for updates but come with lower security than official repositories.<\/p>\n
Update Other Software<\/h3>\n
If your VPS server hosts a web app with its own package manager, like Node.js with npm<\/code>, keep its packages updated. Popular platforms like WordPress also require timely updates due to their large codebases and frequent security patches.<\/p>\n
Step 2) Implement Strong, Unique Passwords<\/h2>\n
\"VPS<\/p>\n
Before we dive into VPS-specific strategies, we need to talk about cybersecurity<\/a> at its most fundamental: passwords.<\/p>\n
There are three ways for attackers to successfully acquire your password to any service: they can make educated guesses based on what they learn about you as a person (your birthday, your favorite hobby, the name of your child), they can use computer programs that use \u201cbrute force\u201d by trying millions of passwords until one actually works, or they can download lists of common passwords in hope that you\u2019re the kind of person who uses \u201cpassword123\u201d on every website.<\/p>\n
It should come as no surprise then that the more complex your password is, the more difficult it will be to guess using any of two strategies. You want your passwords to be both strong and unique.<\/p>\n
