Final answer:
Among the listed devices, a Router is the most capable of providing infrastructure security due to its firewall, VPN, and traffic filtering features.
Step-by-step explanation:
The device most capable of providing infrastructure security among the ones listed is a Router. Routers are designed to connect multiple networks together and manage traffic between them.In contrast, a hub simply broadcasts data to all connected devices, making it less secure. A switch is more secure than a hub as it intelligently routes data only to the intended destination, but it does not have advanced security features like a router.A modem is a device that connects to the internet and enables data transmission over a specific medium, such as cable or DSL. It does not provide infrastructure security.
They are equipped with security features such as firewalls, Virtual Private Networks (VPNs), and the ability to filter traffic, which can block unauthorized access and protect the network from potential threats. In comparison, hubs and switches primarily focus on network connectivity and do not typically include these sophisticated security features, while modems are used for connecting to an Internet Service Provider and have limited security capabilities.
