Oh, the sweet lure of a public Wi-Fi. It\u2019s public, it\u2019s free, and it lets you check your social media networks without wasting your mobile data. Don\u2019t you just love the restaurants that offer free Wi-Fi?<\/p>\n
But before you connect to a free Wi-Fi, you should know about the dangers that come with public hotspots.<\/p>\n
Since these networks are open, they can easily be used by snoopers. The devices on the network could be compromised. Or the network itself could be malicious. What if the hotspot was set up by hackers with the same name as that of the restaurant, leading you to assume it\u2019s a safe network?<\/p>\n
Public Wi-Fi networks aren\u2019t generally encrypted. Compare this to your home network where the wireless traffic gets encrypted between the router and the devices. So if someone is in the range of your Wi-Fi, they cannot see your browsing activity.<\/p>\n
But when you connect to an unencrypted network, it\u2019s visible to everyone that\u2019s in range. Every unencrypted activity you do can be viewed by others \u2013 even what you type into web forms.<\/p>\n
If you\u2019d sign into your bank website, people snooping on you could see that you opened a bank website. However, since your bank website would probably be encrypted, they won\u2019t get to know the username and password you type into it.<\/p>\n
Your 4G enabled device connects to the internet through the cellular network. When you use it, you consume mobile data and you\u2019ll have to pay extra to the mobile company. But the good thing is that all data that\u2019s sent on a 4G network is encrypted and is definitely much safer than a public Wi-Fi.<\/p>\n
While 4G can be hacked (just like everything else), it\u2019s safer than public hotspots. A hacker with enough know-how and the right tools can hack into a 4G network. But to hack into an open hotspot, you\u2019d need just some basic free tools such as Firesheep.<\/p>\n
Let\u2019s say you\u2019re traveling abroad and have no mobile data. The only thing that connects you to the rest of the world is a public Wi-Fi on the airport. You\u2019ll just have to use that. How can you stay safe? It\u2019s simple. Use something that encrypts your data so it cannot be monitored. Something like a VPN.<\/p>\n
A VPN will encrypt your data so your activities stay safe even if you\u2019re on a public Wi-Fi. And it can also work on your cellular network to provide an extra layer of security.<\/p>\n
When you\u2019re outside the range of your home Wi-Fi, public free Wi-Fi can be very appealing but keep in mind the dangers involved with it. It\u2019s best to pay a bit extra on data services than risk your privacy and security.<\/p>\n","protected":false},"excerpt":{"rendered":"
