Firewalls have become an essential tool in maintaining computer network security. Windows Firewall is an in-built component in the Windows operating system that helps protect your computer from unauthorized access through the internet or any network. It can block any program or application that attempts to access your computer without your consent. However, many computer users may wonder what programs should be allowed through the Windows Firewall to ensure that they can use the desired applications and still have adequate protection.
In order to answer this question, it is important to understand the purpose of Windows Firewall. The main function of the firewall is to monitor incoming and outgoing traffic and decide which ports and protocols should be allowed or blocked. Allowing a particular program means that the program can communicate freely through the allowed port or protocol. Hence, determining which programs should be allowed is a balance between allowing ease of use for desired programs while ensuring they do not compromise system security.
