Quizplus · Accepted Answer

Firewalls primarily focus on monitoring and controlling incoming and outgoing network traffic based on predetermined security rules, rather than connecting different LANs or examining IP addresses for the purpose of networking. Their main function is to establish a barrier between your internal network and incoming traffic from external sources (such as the internet) to block malicious traffic like viruses and hackers.
