How Secure is a Linux Virtual Private Server


As the safety of information and data has become the talking point and of most concern among users, site owners find themselves emphasizing on the security level of their websites. That is why we see a lot of people shifting from the cheap and easy shared hosting to more robust and advanced platforms like VPS hosting. VPS, or Virtual Private Server Hosting, is the perfect combination of shared hosting and dedicated hosting since it offers the best features of both. Like shared hosting, it is cheaper to avail and shares a main physical server, and like dedicated hosting, it enjoys a private server environment with dedicated resources. This architecture makes VPS more secure than shared hosting but more cost-efficient than dedicated hosting.

Furthermore, VPS uses either Linux or Windows as an operating system for the server, which makes it high performing. However, between the two options, Linux VPS hosting has evolved to be more efficient and secure than Windows. Here’s why. 

The security level of Linux VPS Hosting

First of all, the very foundation of VPS is designed to make the hosting environment very secure. It uses virtualization to create a network of multiple virtual servers, wherein each server has its resources and are kept separate from the other. This is enabled by a program called Hypervisor, which helps keep the servers isolated and yet, make them run as a comprehensive unit on a common, physical machine. Now, these virtual machines can be created using different techniques. Linux VPS uses KVM or Kernel-based Virtual Machine. The KVM is integrated into a standard Linux kernel and functions as a second level of the Hypervisor. This is then installed on the host machine, which further manages the smaller virtual machines. With this, you can run the kernel on the root node, and operate multiple OS on a single, common, server. KVM also enables the system server to create its extensions of virtualization. It also allows allocation of CPU capacity, storage, bandwidth, disk space, network, etc. thus keeping everything on a virtual server functioning independently. 

Linux VPS also allows more than most programs and applications (WordPress, Python, Perl, CGI, etc.)  to run on its environment. With a Linux VPS, you have more control on your server and its relevant assets, so you can configure it according to your needs, increase security measures, add/remove applications, and so on. 

Linux VPS servers ensure their security levels at all times by running regular updates on the server. Since there is no chance of running an outdated version of any program, your server never becomes vulnerable to threats. Thus, you can keep your hosting system running efficiently and optimally at all 

Summing up…

No matter what kind of business or the size of your website you run, you can never be complacent with its security. And when you are opting for a secured platform like VPS, why not go with the option which ensures better safeguarding of the hosting environment. Always find a good hosting provider who can give you the best deal on your VPS package and offers Linux OS.
