fortress enterprise blog Cloud Enabled Identity Management: Security Challenges

By Brian Lillie (Part 2 of a 3-part blog series)

In the age of increased mobility and bring-your-own-device (BYOD), many enterprises are struggling with how to maintain the high levels of data security they are accustomed to.

In Part 2 of this three-part blog series, Equinix CIO Brian Lillie discusses the security challenges that have arisen as a result of evolving technologies and a changing workforce.


So now we have to think about how to protect this environment. How did we protect it in the old days? We put firewalls around the enterprise and basically nobody could get in. It was a fortress.

But then we started to cut holes in the wall. First you have a door, and the door was maybe your main gateway and it was more than password protected. You’d give your first born to get through the door.

And then there was VPN, so now you could create a tunnel that’s a little bit wider than the door.

And then, because we’re sharing data, maybe between firms or between applications where one application is outside and one is inside, you start to poke more holes in your firewall. You open ports here, open ports there, and pretty soon you have Swiss cheese.

And now, with cloud, the hole is big enough to drive a Mack truck through.

So the idea of the fortress enterprise is really changing. There’s still a place for firewalls, no question, but we’re now trying to take more precautions in terms of protecting the data. Protect the data first and foremost. Protect the data when it’s at rest inside the enterprise, and protect the data when it’s in transit. So encryption and encrypted tunnels are important.
