“One of the greatest challenges to security in the cloud is management,” noted David Meizlik, Vice President of Marketing at Dome9 Security, in this exclusive Q&A with Cloud Expo Conference Chair Jeremy Geelan. “With cloud computing,” Meizlik explained, “the infrastructure is owned and maintained by a third party, so you can’t just walk down the hall to get to your infrastructure.”
Cloud computing represents the advent of a global computing utility that transcends national boundaries. Is that what makes clouds a challenge from a security point of view?
Globalization is more a challenge from a governance and compliance perspective. The greatest challenge to security in the cloud is that traditional security models don’t apply. Take, for example, the firewall. Firewalls were designed to protect the perimeter. The cloud, however, is outside any perimeter, and thus a traditional enterprise IT approach to firewalling is simply not practical.
