Cloud security really boils down to a visibility challenge. I am showing why companies are moving to the cloud and what the security implications are. The security challenges boil down to a visibility, which in turn is a big data challenge. Loggly, a logging as a service provider, addresses this visibility challenge by providing a big data, cloud logging platform. The presentation outlines some visualization use-cases that can be built on top of the Loggly platform to support visibility into cloud operations.
