How do I protect my mobile devices from intrusions via the network? How much can I rely on my service provider to defend me from mobile hacking?
In general, service providers of mobile networks do a good job of keeping the network secure. The public wireless broadband carrier networks incorporate secure storage, mutual authentication and strong encryption, as well as air link ciphering to keep data secure. However, it is still a good idea to use a device firewall and VPN technology to protect all mobile device communication. Also keep in mind that, at times, mobile devices roam into far less secure mobile networks, such as Wi-Fi networks and hotspots. An integrated device firewall and IPsec VPN client are excellent protection mechanisms.
