provider's routers/gateways, network interconnections between ISPs and the
enterprise, enterprise firewalls, enterprise authentication servers, user
location hardware like wireless routers and handheld device itself

infrastructure for mobile security, if possible assuming that such software
supports wireless networks and mobile devices.

on directories, authentication servers, access management servers, VPN
gateways and IP address management tools

device. >
