What is a Software Firewall primarily used for?

A Software Firewall is primarily used to protect a single computer by monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. It operates on the host machine and serves as a barrier that separates trusted internal networks from untrusted external networks, allowing users to set specific rules for data access and traffic control. This protection includes blocking unauthorized access and preventing threats such as malware and hacking attempts.

While other options describe functions related to networking, they do not relate specifically to the core function of a Software Firewall. For instance, protecting a network through hardware typically refers to hardware firewalls that guard an entire network rather than individual devices. Boosting internet connection speed is unrelated to security; rather, it involves optimizing network performance and bandwidth. Managing network resources pertains to organizing and allocating computing resources but does not focus on the primary role of a Software Firewall in safeguarding individual computers.
