Homeworking data protection

Computer World has a good piece on cutting security risks for homeworkers. It also includes six tips from research firm Gartner on how to stay safe:
* Turn off the service set identifier broadcast on all internal, nonpublic, nonguest access points
* Migrate to WPA2-compatible wireless LAN network interface cards (NIC), wireless drivers, supplicants and access points on all new purchases
* Install a personal firewall in every laptop with a wireless NIC
* Keep WLAN card drivers up to date
* Turn off peer-to-peer/ad hoc networking
* Don’t allow wireless and wired NICs to be active at the same time on a client system
