Final answer:
Chuck built a network firewall to protect his business's computer network from viruses and spyware, which is a fundamental cybersecurity measure essential for safeguarding networked data and resources.
Step-by-step explanation:
To prevent viruses and spyware from infecting his business's computer network, Chuck built a network firewall. By doing so, Chuck took a proactive step in securing his network against malicious activities. A network firewall acts as a barrier between the internal network and the internet, inspecting incoming and outgoing traffic based on predetermined security rules. It is an essential component of network security, aiming to block unauthorized access while permitting legitimate communications to pass.
Network firewalls can be hardware-based, software-based, or a combination of both. They often incorporate various security measures, such as packet filtering, stateful inspection, and proxy services. Implementing and maintaining a robust firewall is part of best practices in cybersecurity management. By building a network firewall, Chuck has taken a significant step towards protecting his business's data and resources from cyber threats.
