Nokia Patents Cell Phone Firewall

Wonderful Barry Fox has dug up a Nokia patent for a cell phone firewall which he describes in New Scientist.

"Unlike conventional firewalls which sit on a PC, Nokia's phone firewall is part of the mobile network itself, which acts as a barrier between the device and the internet. It protects mobile devices that connect to the network by setting up "pinholes" through which they can send and receive legitimate data to and from the internet.

Data recognised as belonging to a trusted application is allowed to pass through but unknown packets are automatically blocked. The firewall's so-called pinholes should therefore prevent malicious programmes getting through."
