Which setting allows for monitoring network traffic to prevent cyber threats?

Choosing firewall systems as the correct answer is appropriate because firewalls are specifically designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. They act as a barrier between a trusted internal network and untrusted external networks, making decisions about which traffic to allow or block. By continuously analyzing data packets, firewalls play a crucial role in identifying and mitigating potential threats, thus helping to prevent unauthorized access and cyber attacks.

In contrast, while antivirus software is essential for detecting and removing malware from devices, it does not monitor network traffic in real-time and is more focused on individual endpoints rather than the entire network. Client-server architectures refer to a network design that separates clients from servers but do not inherently provide security features for monitoring traffic. Database management systems are aimed at organizing and managing data but do not typically involve network traffic monitoring or protection against cyber threats.
