One of the greatest reasons that people use a laptop is so that they can surf the web, check their email, or get some work done from pretty much any location. They are then able to return a quick work email from their local coffee shop with free WiFi. When using public WiFi though, unauthorized access to your files, or applications is a possibility.
When you are in your home, sharing files, printers, or screens is common. You have a private network where only certain people can access your network. When you are in a public location though, this network control isn’t in your hands. But here is a way to help control the sharing on your own computer:
- On a Windows disable your sharing options. You can disable network discovery and public folder sharing.
- In Mac OSX, find the sharing panel in the system preferences and make sure all “sharing” options are unchecked.
The next important step is to make sure your firewall is “up.” This keeps users from lurking at your computer, and your computer files. Checking the status of your firewall can be found in your system preferences. Lifehacker says that “your firewall is not an end-all, be-all protector, but it’s always a good idea to make sure it’s turned on.”
Another good step to take is to turn off your Airport or wireless if you are not using it. If you are writing a paper at Starbucks or doing some math homework, best chances are that you will not need to surf the web.
These are just a few steps to take, surely there are more measures that helps secure someone’s personal safety. Be safe!
