How Windows Firewall Works
Windows Firewall operates based on a set of predefined rules that dictate what traffic is allowed to pass through. These rules can be configured to allow or block specific programs, ports, or services. For instance, when you install a new program that requires internet access, Windows may prompt you to allow it through the firewall. By default, Windows Firewall is set to block all incoming traffic unless a rule is created to allow it. This approach ensures that your computer remains protected from unauthorized access attempts.
Types of Rules in Windows Firewall
There are several types of rules that can be configured in Windows Firewall, including:
- Program rules: These rules allow or block specific programs from accessing the internet.
- Port rules: These rules control traffic based on the port numbers used by network protocols.
- Service rules: These are used to allow or block Windows services from communicating over the network.
Understanding these rule types is essential for managing Windows Firewall effectively and ensuring that your computer and data remain secure.
