Joe works for a company that has a traveling sales force. The company has asked Joe to research a way for the sales force to have real-time information on the availability of its salable products. The company has an intranet application that allows it to see up-to-the minute information. The company does not want to make this information public. What should Joe recommend?

Joe should recommend a VPN.

Explanation:

A VPN is a Virtual Private Network that allows you to create a secure connection to another network over the Internet. So when a different server is trying to connect with your server, the VPN will encrypt the connection so that only public information is shared. It can see the server address rather than than your address and encrypt data.

Joe can use this facility to protect the company's information from being publicly accessible. VPNs can be used to protect your data from servers connected through different WiFi connections.
