Why Do You Need A Firewall?
A firewall, in essence, is a security system or structure that keeps an eye on all incoming and outgoing traffic on a specific network system. It does so through a definitive set of rules. So, it becomes easier for the module to keep unauthorized traffic away from your system.
Usually, a software firewall system comes as a pre-installed model in every Windows or Mac product. Nonetheless, if you are trying to protect an entire network, you’ll need the help of a hardware-based firewall infrastructure. It’s expensive but effective in more than one way.
How Does It Work?
Each firewall module offered by a specific manufacturer is different from the others. Thus, it might be better if you could ask about the same to your managed firewall service provider to get a clearer idea about it. In any case, here’s a basic idea of how it actually works.
- A firewall primarily focuses on filtering your data. And it does so by evaluating the data of the sender’s address and what the information is meant for.
- Secondly, it also checks if there’s any harmful substance available in the data. In case it has found something, it will either delete the data or ask you not to open it.
As mentioned before, a firewall software program, when it comes with an OS, will always be pre-installed. So, it might be best to check if everything is activated or not.
The Benefits Of Using A Firewall
A firewall can be an excellent pair for your already-existing antivirus system. It can bolster a network infrastructure even more and ensure that you are protected from every side.
Here’s how it usually benefits the users.
1. Protection Against Unauthorized Access:
A firewall acts as a barrier between your computer or network and the outside world. It can prevent unauthorized access to your system by blocking traffic from unknown or untrusted sources. This is especially important for businesses that need to protect sensitive data or proprietary information. By using a firewall, you can ensure that only authorized users can access your network or computer.
2. Blocking Malware And Viruses:
A firewall can help to prevent malware and viruses from infecting your system by blocking traffic from known malicious sources. Malware and viruses are often spread through email attachments, file downloads, or malicious websites.
A firewall can block traffic from these sources, reducing the risk of infection. Some firewalls also include antivirus and malware detection capabilities, providing an additional layer of protection.
3. Network Performance Improvement:
By blocking unwanted traffic, a firewall can improve network performance and reduce bandwidth usage. Unwanted traffic, such as spam or malicious traffic, can slow down your network and consume bandwidth. A firewall can block this traffic, freeing up bandwidth for legitimate traffic and improving network performance.
4. Monitoring Network Traffic:
Firewalls can monitor network traffic in real time, which can help identify and block unusual or suspicious activity on your network. This is especially important for detecting and preventing cyberattacks, such as DDoS attacks or hacking attempts. A firewall can also generate logs of network traffic, which can be used for troubleshooting or forensic analysis.
The Bottom Line
A firewall isn’t perfect, especially when it comes to taking care of your network system. But if you pair it up with an antivirus, it can do a world of good for you.
However, still, before you buy something from the market, it might be better for you to use a reference or ask an expert. They can tell you about what you need to choose for your case.
