Answer

Brief Explanations:

A firewall is a network security system. It monitors and controls incoming and outgoing network traffic based on predetermined security rules. Its main function is to act as a barrier between a trusted internal network and an untrusted external network (like the Internet). By identifying and blocking unauthorized network traffic (such as traffic that might be carrying malware), it reduces the risk of malware infections. Scanning and removing malware from files and emails is more the function of antivirus software. Providing a safe space for testing potentially harmful software is what a sandbox does. Ensuring all data transferred over the internet is encrypted is related to encryption protocols (like SSL/TLS) rather than the core function of a firewall.

Answer:

A. A firewall helps identify and block unauthorized network traffic, reducing the risk of malware infections.
