Question

Quizplus · Accepted Answer

A proxy server acts as an intermediary between a user and the Internet, ensuring security, administrative control, and caching service. It can also help filter out malicious traffic and prevent unauthorized access to the network. A firewall and router are also important components of network security but do not necessarily provide the same level of intermediary function as a proxy server. A hub is not a security device and simply acts as a connection point for multiple devices on a network.
