Firewall

A firewall is a device that allows us to control internal and external traffic. Thanks to this wall, the software on our computer does not provide information without our permission. In other words, the exchange of information from the computer to the internet is prevented from going beyond our permission. Firewall, the Firewall, is briefly a computer defense mechanism hardware. All computers connected to the Internet via a network are under the threat of many viruses, malware and hackers who can infiltrate the computer.

Firewall is the hardware that protects the computer from these threats. The firewall builds a wall against malware and prevents it from infiltrating the computer through the network. In short, Firewall is one of the methods to stay safe on the internet. Firewall types, which are hardware-based or software-based, have certain rules within themselves.

Hardware based Firewall is designed for network systems that need stronger protection. Software based Firewall can be used for single network and home computers. The firewall needs to be on all the time and updated as needed to keep your computer protected. The passage of certain data across the Internet, also known as packet transmissions.

The firewall constantly checks these packets in and out. When the Firewall allows some packets to enter and disallows others, this is called packet filtering. Another form of Firewall data control is Proxy Service. In the Proxy Service, the Firewall records incoming data, performs a detailed review and compares it with other data. If there is a software code marked as malicious in the analyzed data, the package is marked as malicious and the Firewall does not allow this package to enter the system.

Windows Firewall, is one of the most widely used firewall types worldwide. The new versions of Windows Firewall, which can be used free of charge with computers that have Windows software, are also much improved compared to the past. However, it is still useful to support the firewall with an antivirus program when using Windows Firewall for a completely secure internet usage.

While the firewall is an extremely important piece of hardware that makes internet use secure, we often see many people asking about “firewall shutdown”. So, if the firewall is so important, why is there a need to turn it off?

For various reasons, various firewall hardware, including Windows Firewall, can detect pages you want to open, sites you want to download from, or various downloads as malware.

In this case, the firewall does not allow the operation you want to perform. For this reason, internet users may have to turn off Firewall or change its settings. If you encounter such a situation, you can change your Firewall settings or turn off your firewall for a limited time.

By selecting and saving the features you want within the firewall application, you can also ensure that your firewall behaves according to your needs when using the internet.Firewall shutdown should be the last option to use when the choice of options does not meet your needs.

As long as the firewall is on, it protects your computer and blocks malware or viruses.If you scan your firewall periodically, you can see that the firewall prevents many attacks even within a day. Not only viruses and malware, but also security risks are problems that are eliminated by the firewall. This is why it is vital that all computers connected to a network have a firewall.
