Employee’s love them, Network Administrators hate them, the advent of more function packed handheld devices have sparked a re-evaluation of the threat these small devices pose. Traditionally, networks were quite safe for to gain access to it you needed to be hooked up to the network, physically with a LAN cable. Now that the shift to wireless has become the network engineer’s best friend the network has surely been simplified and companies are switching to the new technology. Thy no longer needed wires and all existing computers are either replaced with ones that support Wi-Fi or bought individual dongles that allowed connection within the office. That was still an easy security agenda for they usually had a range of a couple of hundred feet.
Then came wireless internet hotspots which commercial developers started to put up to get more workers out of the office into their shops allowing them to work while, say having coffee. That’s where the problems began for the more office correspondence left the walls of the office, the more harder was it to secure. VPN’s were implemented that allowed a secure channel within existing networks making it a bit better. But that was still quite vulnerable to attack and security experts needed a better way of securing corporate data where-ever the user might be. Projections by business and security analysts estimate volume to increase to 100 million email transactions to and from outside the office locations that is still causing nightmares as the next step is found in the drive to secure this network without physical bounds.
