Correct Answer:
B. To prevent unauthorised access to a private network
Explanation:
The correct answer is to prevent unauthorised access to a private network.
A computer firewall acts as a security barrier between a private internal network and the public internet. Its main goal is to monitor and control incoming and outgoing network traffic based on predetermined security rules. By filtering this traffic, a firewall blocks malicious or unrecognized attempts to access the system, thereby protecting sensitive data and preventing cyberattacks. Unlike antivirus software that removes existing infections, a firewall focuses on proactively securing the network perimeter against external threats.
