Tips for Mobile Security -- Home Network

If you take your work laptop home and connect it to your home network, how do you ensure that your data is secure?

Treat your home network (whether Ethernet or Wi-Fi) as you would a public network. Don't trust your ISP. (continued...)

With a Wi-Fi home network, you should also implement the optional encryption between your mobile device and the router or access point. If possible, enable WPA (Wi-Fi Protected Access), which automatically assigns and periodically updates encryption keys for each mobile device. WEP (Wired Equivalent Privacy) is not as secure as WPA, but it's better than nothing at all.

Also, assign a secret username and password to the Wi-Fi router's administration interface to keep hackers from configuring it to their advantage. You can also disable SSID (service set identifier) broadcasting on the Wi-Fi router, and manually set the SSID in the mobile device. This keeps your neighbors from finding (and using) your network.
