All you computer experts out there - are 'we' crazy to be using wireless laptops etc?
No, Please keep using it... I enjoy seeing the pictures of your family....
:great:
Seriously, computer security is like any other security. You cannot keep someone out of something they are determined to get into, you can only make it harder and more costly.
If someone wants to break into your house, they will. You can make it hard, you can get alarms, strong doors, locks and dogs, but they will keep working it until they get it, IF they are determined. Same thing with computers.
WEP = Really insecure these days.
OPEN = OK, you are asking for it....
Public - I use them, but KNOW what you are attaching to, and don't access private information that is not on a secure website on a public WiFi.
WPA - Tough to crack, but can be done with enough time. What you have to ask yourself is what is the most important, secret thing that I have on my computer, and what would happen if it was on the front page of the newspaper tomorrow, and take security precautions accordingly.
You also want to ensure that your home network is secured, because even if you have nothing that you care about anyone else seeing, someone can use your Wireless Signal to launch attacks that can point back to you as the attacker. When the RIAA was filing rampant lawsuits about music downloads, I am pretty sure they caught some innocent folks in the wreckage by this happening.
