What is the primary function of a firewall in workstation configuration?

The primary function of a firewall in workstation configuration is to monitor incoming and outgoing network traffic. A firewall acts as a security barrier between a trusted internal network and untrusted external networks, such as the internet. It examines data packets and determines whether to allow or block them based on predefined security rules. This crucial role helps protect the workstation and the broader network from unauthorized access and potential threats like cyberattacks, malware, and data breaches.

By analyzing traffic, a firewall can help enforce security policies, prevent harmful data from entering the system, and maintain the integrity of sensitive information. The monitoring is not just passive; firewalls can actively prevent unwanted connections and alert users to potential security incidents, thereby playing a key role in maintaining a secure computing environment.
