If you are on a Shared Hosting plan and you are looking to migrate to a hosting plan that can allow you to deal with the sudden surge of traffic inflow on your website, then you might consider an upgrade to VPS Hosting. The Linux VPS Server is a cost-effective plan that is considered by many as a natural upgrade from a Shared Hosting server. However, although a VPS Server is more secure than using a shared server, there are steps you can take to optimize the security of the virtual server further and keep cyber attacks at bay.

But before that, it is important to understand how a Virtual Private Server works.

What is vps hosting?

Virtual Private Server, or VPS, works on the principle of server virtualization, where a single physical is split into multiple virtual servers by the use of an application called the hypervisor. Each virtualized server is allocated a dedicated amount of resources which can be scaled as per the client’s requirement. The advantages of using a VPS Server are many; however, our main concern in this article is the security aspect of a Linux VPS Server.

Some Ways To Secure Your Linux Vps Servers

1. A strong password that too must be changed periodically

A user should always set a strong password and avoid passwords that can be easily guessed. A mix of alphabets, numerals and special characters should form an ideal strong password. Moreover, these passwords should be changed at regular intervals to prevent hackers from gaining root access to your server. It is advisable to make use of the SSH feature instead of a password to login to your server.

2. Use a firewall

A firewall acts as a gatekeeper and forms the first line of defense. It does not allow unauthorized traffic to enter and keeps malicious attempts to breach the cyber security at miles distance.

3. Update server software and perform regular offsite backups

Having a backup of the server can help you reinstate to the best possible previous state in times of a disaster. Updating to the latest version of security applications and other patches can also make your VPS Server better optimized.

4. Install antivirus software

Although a good firewall does prevent malicious traffic from entering your server, some malicious files are designed in such a way that the firewall fails to detect this file. At this point in time, the antivirus comes into the picture to detect and avert an upcoming threat.

5. Encrypt all data transmission

Hackers often target data that is in transit over a network. Thus, one should ensure to encrypt all data transmissions. All encryptions should be done using a public key, and only a private key should be used to decrypt it.


There are millions of hackers trying to find a weakness in your VPS Server, and if your VPS lacks basic security standards, you can become their next target. But by following the above-mentioned steps, you can secure your Linux VPS Server and save yourself from losses.
