What does a firewall primarily protect a network from?

• A. Hardware failures
• B. Physical theft
• C. Malicious attacks
• D. Power surges

Answer: (C)

A firewall primarily protects a network from malicious attacks by monitoring and controlling 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 untrusted external networks, such as the internet. Firewalls can block unauthorized access to network resources and prevent various types of attacks, such as malware, intrusion attempts, and other security threats. By filtering traffic, a firewall helps ensure that only legitimate users can access certain resources and that any potentially harmful traffic is denied. In contrast, aspects such as hardware failures, physical theft, and power surges involve different types of risks and protective measures. For instance, hardware failures may be mitigated through redundancy and backup systems, physical theft is addressed through security personnel or devices, and power surges can be managed with surge protectors and uninterruptible power supplies (UPS). Each of these concerns falls outside the primary function of a firewall.
