Explanation

A Virtual Private Network (VPN) is a network security device that allows remote users to securely connect to a private network over the public Internet by encrypting their communication (see ISC2 Study Guide, Module 3, under Virtual Private Network). A VPN creates a secure tunnel between the remote user and the private network, allowing users to access resources on the private network without exposing their identity. A firewall is a network security device that protects a network from malicious traffic. In contrast, an Intrusion Detection System (IDS) detects malicious activity on a network. A proxy server is a server that acts as an intermediary between a client and a server, allowing the client to make requests from the server without revealing their identity.
