Question

Quizplus · Accepted Answer

A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predefined security rules. It helps to block unauthorized access to a computer or network by analyzing network traffic and either allowing or blocking it based on the configured rules. Bridges are used to connect two or more network segments, VPN is used to create secure connections between two or more devices over a public network, and WEP is a type of encryption used in wireless networks. While these technologies can enhance security, they do not necessarily help block unauthorized access to a computer on their own.
