As organizations continue expanding their adoption of the public cloud, many IT and security professionals are beginning to see that they need improved cloud-monitoring and cloud-auditing capabilities. By cloud monitoring, I'm referring to the process of identifying cloud use within an organization and then evaluating if there are data privacy and/or compliance risks that need to be mitigated.

Forrester's John Kindervag was quoted in the Washington Post article I read saying that "whatever money Target thought they were going to see the holiday season just got flushed down the data breach toilet." The costs they potentially face include ever... (more)

From the Stone Age to Today – History of Security Infographic

When you think of security do you think of locks, guards or even your home security alarm? At the moment security is more likely to bring up thoughts of hackers, PRISM and well-publicized data breaches. Of course I think of the cloud when discussing security. In the contemporary world of information security, enterprises and institutions are increasingly acknowledging the need to find new ways to protect their most sensitive information when using cloud applications. Given the speed of advancements in the technology world, enterprises need to be constantly changing, adapting and ... (more)
