A website is a digital asset – it represents a business. If a website is not secure, then cyber-attacks can damage the reputation of the business, cause loss of revenue and data, and dent customer trust. Hence, for most websites, security is the topmost priority. Since a site resides in a web host, the security of the site primarily depends on the security of the host. There are different types of hosting services available, with each offering maximum site security. In recent years, Virtual Private Server or VPS Hosting has managed to gain popularity among site owners for being a secure hosting service. A VPS is created by a process called server virtualization. In this article, we will talk about how server virtualization ensures site security in VPS Hosting.
VPS and Server Virtualization
To create a VPS, a web host uses a server virtualization program called a hypervisor to divide a physical server into several virtual servers. Each virtual server has its own hardware, software, applications, and other resources. Further, all virtual servers are isolated from one another.
A hypervisor has multiple-level security with tight controls that prevent any unwarranted access to the system. When you buy a VPS Hosting service, your website is hosted on one such virtual server. Here is how server virtualization ensures site security in VPS Hosting:
Better System Control
Server Virtualization ensures that the virtual servers created are completely isolated from each other. Hence, the host can provide complete root access that allows the user to restrict access to the server and create access rules. Users can also set the security protocols as per the requirements of their site. Although the responsibility of server management lies with the host, your VPS is completely in your control. This allows you to limit the access of your VPS to trusted users only.
Since the VPS has dedicated resources, the storage servers are programmed using the hypervisor too. Therefore, even the storage mechanism is secure as it follows the same security features as the VPS. This means that you don’t have to think about securing the server and storage separately. The entire VPS environment is protected.
Shared yet Secure
Although multiple websites share the same physical server, the process of server virtualization ensures that each virtual server is complete in itself (has no external dependency), and the performance of one virtual server does not affect others (account isolation). Hence, even if one virtual server is infected with a virus or malware, the hypervisor does not allow it to infect other virtual servers.
As you can see, server virtualization ensures that the virtual servers created using its hypervisor are designed to be secure. You can also take the security of your VPS to the next level by taking additional security measures. Before you buy a VPS Hosting plan, ensure that you check for reviews pertaining to the security of the VPS provided by the host. Good Luck!
