Recently, USA Today journalist Steven Petrow wrote about his using in-flight Wi-Fi to send emails while flying on an American Airlines flight. Upon landing, Petrow was approached by one of the other passengers who informed him that during the flight he had hacked into Petrow’s laptop as he had done to other passengers as well. The hacker proved his assertion by recounting to Petrow the contents of the emails he sent and received. The lesson here is one that too many of us forget, namely that public Wi-Fi is not secure. However, with some precautions it can be made safer.
Whatever electronic device you are using to connect to a Wi-Fi network, whether it is a computer, laptop, tablet or smartphone should be equipped with security software. In addition, you should have encryption software so that your communications are encoded. You also should go to your settings and turn off sharing. In addition, you should make sure that your firewall is current and turned on. Finally, and perhaps most importantly, you should consider using a Virtual Private Network (VPN) which enables you to send your communications through a separate and secure private network even while you are on a public network. A good VPN that you can use for free is CyberGhost which you can get by clicking on this link. http://www.cyberghostvpn.com/en_us
