A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external networks, such as the Internet.
The FRITZ!Box firewall is a hardware-based firewall that is integrated into the FRITZ!Box router. It provides protection against unauthorized access to the home network from the Internet. The FRITZ!Box firewall is configurable, allowing users to define rules to allow or block specific types of traffic. The firewall also includes features such as intrusion detection and prevention, and parental controls.
