Since tablets are designed to be mobile, that means that the tablet is likely to be connected to the Internet via Wi-Fi hotspots. This makes it important to ensure the security of both the tablet and your home network.
As it turns out, when Ubergurl was organizing the Lenovo online Malware and Security event last year, she asked me if I would write an article on tablet security tips. You can find it here: Tablet Security Tips.
If you have other questions, don't hesitate to ask.
