Travellers are typically more vulnerable to hackers intercepting their data: if you’re visiting somewhere and using wireless services, you’re typically relying on the operator of the network to be trustworthy and have a secure service.
In reality, the risk of harm is very low, especially since poker site traffic is encrypted. However, a typical internet session will also include unencrypted but sensitive data being transmitted: for example, if you log in to an online discussion forum, your password is typically transmitted in a non-encrypted fashion.
You can reduce this risk by using a VPN – a virtual private network. In effect, your PC creates a secure and encrypted connection to a server, so that all the information being transmitted is encrypted.
There are various commercial VPN services available, but if you have a home Windows PC that you leave on, you can easily route your traffic via your own computer, giving you all the security that you normally enjoy at home.
Of course, your bandwidth may be limited (all the data needs to be sent from your travelling PC, to your home PC, and then from the home PC to the final destination) but this is an easy-to-setup security option.
