It is a well-known fact that the Internet is actively used in every aspect of life and is always needed. A firewall ensures your security while surfing the Internet and downloading things. By setting up a VPS firewall on your VPS, you can filter and block threats between public and local networks.
While browsing the Internet, you may visit unsafe websites, knowingly or unknowingly. A firewall is a system that warns you when you enter these sites and tells you that your computer is at risk.
The firewall controls the data coming and going from the network, ensuring that potential threats are filtered and ultimately blocked. This system, which is actively used on the Internet, is improving daily. However, in some cases, malicious sources can pass through the established filter system. This shows that the Firewall system needs to be further strengthened.
What Does Firewall Do?
Firewalls work on a hardware or software basis and ensure the security of network traffic. To provide this security, the system applies control steps such as IP filtering, web filtering, port filtering, or content filtering.
Today, many operating systems rely heavily on firewall systems tailored to their software foundations. They also have their Firewall systems that direct data transfer between their networks. Although the widespread use of computers and the Internet is a new technology, the use of the Firewall system dates back to the 1980s. Now, in 2024, it is necessary to set up a VPS firewall, as security issues are more severe than in previous years.
A firewall examines data traffic on the network with a pre-determined filter. It blocks data packets from unsecured sources with the help of these filters. With this precaution taken, it becomes possible to prevent malware and dangers from coming over the Internet.
The firewall system is located on the ports where data is shared on the network. For example, the system whose source address is 172.18.1.1 is ensured to reach the target 172.18.2.1. This example best explains what a digital firewall does.
Why is Firewall Important?
Network traffic always needs to be inspected, regardless of whether it is malicious. A modern mechanism installed can ensure the system’s correct and secure operation.
Connecting personal computers to other networks or the Internet raises security issues. The device needs protection in these situations. Hacking, malware, and fraudulent activities are common dangers in this sense.
Once your device network is infiltrated by malicious people or software, your device may be accessed, and various threats may occur. Therefore, your computer is at risk 24 hours a day. However, a firewall system can eliminate these risks.
How to set up a VPS firewall
Installing a firewall often requires easy root access to the server. It inevitably involves some important command-line work that many people need to become more accustomed to. However, as the steps to install CSF on a Linux VPS will show you, it is easy you need to do the following:
Navigate to usr/src and download CSF
The command you need to use is:
- Cd/usr/src/
- wget https://download.configserver.com/csf.tgz
Your VPS will automatically download the latest version of CSF from the official website and place it in the /usr/src/ directory.
Extract CSF files
The following command will extract all files in the csf.tgz archive:
- tar xzf csf.tgz
Go to the CSF directory and run the installer
The command you need to use is:
- Cd csf
- sh install. sh
Run this to start the CSF installer. It will check if all prerequisites are present before installing the application. If you encounter critical errors, you may need to install Perl and libwww before continuing.
By default, they should be available for all supported Linux distributions. Still, if they are not available – the command you need to use is:
Disable any existing firewalls and configure CSF
If any other firewalls are running on your computer, you may need to disable them using the systemctl command. The CSF configuration is located in /etc/csf/csf.conf. Figuring out what settings you need to apply to set up a VPS firewall to your exact specifications should be easy. You will need slightly different commands. However, if you have a self-managed VPS with root access, the process is relatively simple.
The role of your hosting provider
Still, it’s understandable that many website owners might want to do it only for some of them, especially if they’re not used to using a terminal. For them, hosting plans are the perfect solution. You are free to use all its hardware resources and install applications as you see fit. The difference is that you don’t need to do any sys-admin work. Instead, your hosting provider uses their expertise to ensure you set up a VPS firewall correctly and that it works properly at all times.
If your experience is limited and you feel uncomfortable setting everything up yourself, this is the preferred setting. However, avoid setting yourself up for strict defaults that may or may not meet your project requirements.
Suppose you need to use an application that requires a specific set of firewall rules. In that case, your hosting support team must be able to check if the settings can be changed quickly. If so, they will apply the new configuration for you. If you need help, they should be able to point you to the right self-management plan and, ideally, provide you with information on suitable firewall solutions.
