How to Secure Your VPS Server

 Security becomes one of the important factors when it comes to protecting data. Whether a company is a big giant or a small-medium enterprise the concern of hacking and cracking cannot be ignored. 

Virtual Private Server (VPS) is one of the most popular types of service provided by a hosting provider. There are popularly two types of VPS available in the market. The Linux and the Windows. Linux is known for its best security practices. Talking about its competitors like windows does not have many security protocols that Linux follows. Linux Security Model is much stronger than any other OS. However, they do own some glitches which should be taken care of. And no VPS is highly safe and secured. Therefore, you should always take some security measures to prevent vulnerabilities. 

Here in this blog, we will know about how you can protect or secure your server on the web.

Upgrade to the latest software

Vulnerabilities find it easy to enter into outdated software. You need to stay updated all the time and should run all the important updates of your OS. Rather than manually performing these types of updates you can easily automatize the process. Linux utility commonly known as cron jobs can be a helpful thing where you can easily schedule a command which would run on a particular date and time to perform a function. You can control it through the control panel. If you make use of the Content Management System (CMS) you should keep a regular watch for the updates available and install them at priority.

SSH Login 

SSH is the most commonly used method which helps you to set a connection between computers, for logging in to a server. 

Using SSH login can invite brute force attacks. These types of attacks mean that someone is trying to guess your password by entering similar passwords to log in to SSH.

For this very explanation, we suggest changing the default SSH 22 port login secret key to a tweaked one. Solid passwords for the most part comprise a mix of upper and lower-case characters, numbers, and non-alphanumeric characters.

To change your default SSH login secret key, basically login to your VPS and find the document/and so forth/ssh/sshd_config. Presently change PermitRootLogin from the default YES to NO. For cutting-edge security, you should consider utilizing SSH authentication rather than password authentication, which is more impervious to brute force attacks. 

Remember, notwithstanding, that when you incapacitate root logins without allocating approved admittance in advance, you might keep yourself out of your VPS.

Keep an eye on server logs

Keeping an eye on your server logs will help you to get full control over your VPS server. If you take care of all the system and software logs it will help you to prepare in case the situation gets worse. 

The monitoring includes resource usage, traffic levels, and user activities, and so on. This will not only give you full control but also will help you to figure out the solutions to the security issues that can hamper your goodwill.  

For monitoring activities, you can also set up an email notification alert.


A firewall acts as a door that keeps an eye on incoming and outgoing traffic and decides to allow or block the traffic, defined by a specific security rule. 

A firewall will protect you from unwanted traffic. 

Linux is much popular in terms of security and so it comes pre-installed firewall within it. To control and manage firewall settings you can install ConfigServer Firewall. This will provide you best VPS security with an advanced interface. 

 You can select both a pre-installed firewall and a customized firewall but in both cases, you need to configure some major things:-

1) Filtration of Traffic

2) Allowing and Blocking IP Address

3) Preventing ports that are not needed for scan prevention

4) Monitoring and keeping a regular check 

5) Maintaining regular up-gradation to prevent security issues. 


Limit Usage Access 

In terms of VPS security getting secured in terms of secured areas where users can operate easily and defining the restricted area is important. 

Many people set different file permissions. A tool like SELinux can help you to control network interfaces, files and file systems, etc. 

Controlling user access to prevent sensitive data. You can initiate this by file system such as Cloud Linux. This will lead you to manage the user set of resources and files. 


Malware Protection

Protecting and securing your VPS by a firewall is a good thing because we know that this will help to protect you from unwanted traffic and will secure your VPS with vulnerabilities. However, a firewall works with incoming traffic. You need to also safeguard from the files that are already present in your VPS to prevent unwanted causalities. 

Here comes the need for malware protection software for VPS security. It will help in the detection of unwanted activities and will restrict unwanted files.

There are many malware protection software available in the market from which you can select the most popular one.

SSL certificate

SSL certificates help you to build authenticity and to create an encrypted channel between server and client. This ultimately secures your data privacy.  

An SSL certificate ensures that the website is safe and trustable that it’s safe for transmitting files or entering personal details.

SSL configuration requires some technical knowledge. Linux vps secure your business from malwares and hackers.And so you may take the help of a system administrator for the same.


In conclusion, security issues can hamper all you’re working on within few seconds. Whether you opt for any type of hosting security should be kept at high priority. To prevent vulnerabilities like brute force attacks by setting a strong password or two-factor authentication, keeping an eye on unknown attachments is the basic thing that you can do. Talking about VPS if you are going to own a Linux-based VPS you would face lessse3curity issues than that any other operating system.
