Many companies tend to jump into the cloud before thinking about security. They may think they’ve thought about security, but when moving to the cloud, the whole concept of security changes. The security model must transform as well.

Moving to the cloud and staying secure

Most companies maintain a “castle, moat, and drawbridge” attitude to security. They put everything inside the “castle” (datacenter); establish a moat around it, with sharks and alligators, guns on turrets; and control access by raising the drawbridge. The access protocol involves a request for access, vetting through firewall rules where the access is granted or denied. That’s perimeter security.
