Whenever you use an internet connection in a public or publicly accessible place, you put your data at risk. The internet connection may be a free or commercial Wi–Fi hotspot, an Ethernet network jack in your hotel room, or a network drop in the office you’re visiting. All data you send can be intercepted easily and quickly by persons unknown, without your knowledge. Your data may be your email usernames and passwords, your emails, Instant Messages, web passwords, and all the web pages you visit.
