Question

Quizplus · Accepted Answer

A firewall is specifically designed to prevent unauthorized access to a network by monitoring incoming and outgoing network traffic. It examines each packet of data passing through it to determine if it meets certain criteria or filters, such as source and destination IP address or port number. If the packet fails to meet these criteria, it is blocked from entering or leaving the network. Routers, switches, and SSL are all important network components but they do not provide the same level of security as a firewall.
