How do I ensure my data is less vulnerable when accessing Wifi in public places?

Turn of filesharing, and enable a firewall on the PC.

Are you referring to the data on your Machine or the data being transmitted over the WiFi connection?

How do I ensure that the both the data on the machine and those being transmitted are safe?


I've got a firewall running and file sharing has always been turned off

Data on your system should be safe. However it is not possible to guarantee the security of data passed over an unsecured wi-fi connection.

With a domestic WiFi system you would set up encryption, however on a public hotspot this isn't an option and by definition of being public, it is unencrypted. Remember, that the internet itself is not secure. Data sent over the internet that is unencrypted and can be intercepted. Your best defense is to be vigilant about what you are doing on-line. Make sure that any sites that you are entering personal details in are secure. These would typically have https:// in the address bar instead of http:// You will also see a padlock symbol (Bottom right in Firefox. To the right of the address bar in IE) check the certificate issued by clicking on the padlock. Make sure that it is properly signed. Your browser should let you know if it doesn't match the site though. If you are working at public hotspots and your employer has a VPN connection to your corporate network, use it. This creates a secure tunnel between your PC and your work network.

The network needs to be encrypted. If it is an unsecured network, then there is no encryption, and if you don't control the network you have no control over the encryption. If you enabled encryption you would not be able to connect to the network as other devices would not understand the data you are sending.

Then, how vulnerable am I when connecting to an unsecured wifi hotspot?

Could people be viewing what I am viewing on my screen or log in to my email acount when I have selcted "log me on automatically everytime" setting?

No. People can intercept the data being transmitted over the connection. They can't see your screen, or access your data. If you are using a secure website for webmail for example, then all the data is encrypted and intercepted data will be meaningless. If though you posted on this website, it might be possible for someone to see what you posted.

So long as you only perform sensitive actions over servers where the URL starts with https you shouldn't have anything to really worry about.

How easy is it to intercept the data being transmitted over the connection?
is a wifi connection more vulnerable than a regular phone line internet connection in that way?
