De-perimeterization and life after the firewall

NO BORDERS

Article from Issue 89/2008

Enterprises and organizations used to feel protected behind the firewall, but now VPNs, e-commerce, web services, and Web 2.0 have put an end to the comfort. The network perimeter is losing its significance, and the time has come for a new approach to security.

Firewalls used to be the pride of any security department. A welldesigned firewall protected the internal network, and a lot of ports needed to be open on the firewall. Servers advertised their services to anyone on the LAN.
This black and white view of the secure internal network and the evil external network was never really as simple as it looked – identity thieves and disgruntled colleagues have always been a part of the corporate scene – still, the system seemed to work somehow. Without firewalls, the current conception of the Internet – with online shopping, home banking, and VPNs – would be totally unthinkable.

    The eyes of the tech world are all on Google with the announcement that Google's Compute Engine cloud service is now open to the public. The new service is Google's answer to Amazon's AWS cloud system and is poised to capture some of the same customers. Many are predicting Compute Engine will be a game changer, as the sports addicts would say: a historic move that will change the whole landscape – and they might be right. If anyone has the power and personnel to take on Amazon, it is definitely Google, although it is worth remembering that, after striking it rich with search, Google's later attempts to swallow whole industries have not always been as successful as the experts predicted.
