Quizplus · Accepted Answer

All of the options given (network router, personal firewall, and hardware that uses NAT) can be used to block unauthorized access while allowing authorized communications on a device or network. Network routers can be configured to block certain ports or IP addresses, personal firewalls can provide granular control over inbound and outbound traffic, and hardware that uses NAT can hide the IP addresses of devices on the network from the outside world, making it more difficult for attackers to target specific devices. Using a combination of these measures can help to ensure the security of a device or network.
