''There are some risks associated with public access points,'' says the head of technology for Asia-Pacific at security software company Sophos, Paul Ducklin. A security adviser at AVG AU/NZ, Michael McKinnon, says: ''The best assumption is you're not secure.''
But both specialists say you can still use public internet if you keep a few things in mind. Here are some simple rules to follow to connect safely.
1. No password, no go. Security depends largely on whether the network is open or secure. Basically, does it have a password or not? ''When you are using an access point, you need to be using a secure connection for everything,'' Ducklin says. ''If it's not an encrypted access point, then anybody can see what you're doing.'' If the network doesn't have a password, find one that does.
2. No sensitive content. ''I certainly wouldn't be using any sites that required a credit card,'' McKinnon says. Even if a public network has a password, it is best to save internet banking or credit card payments for private home or office networks.
3. Browse securely. Wherever possible, use sites that are secured with SSL encryption. This can be achieved by typing ''https'' before the website address, rather than just ''http''. Be sure to physically type this into the browser, not click on a link that claims to be secure, as these can often be false.
4. VPN. If you are on the go but need a constant, secure connection, a mobile virtual private network, or VPN, is a good option. The software will encrypt your traffic but maintain your login session as you move across different access points.
5. If all else fails, use 3G. If you do need to conduct sensitive browsing, such as internet banking, while out and about, your safest option is to either find a private network or revert to 3G mobile internet. ''A 3G connection is inherently encrypted by default,'' McKinnon says. ''[It] does tend to be a little more secure than an open wireless network.''
Beyond this, the general rules of internet security apply. Make sure your software is up to date and use an antivirus program (yes, even Macs can get viruses).
''Nothing's perfect,'' Ducklin says. ''It's like going to a street market rather than a well-run shopping centre - you can get some great bargains, but sometimes you're on your own.''
With this in mind, you might just be able to save yourself a few bob.
