Can data lakes solve cloud security challenges?

“Data Lake” is a proprietary term. “We have built a series of big data platforms that enable clients to inject any type of data and to secure access to individual elements of data inside the platform. We call that architecture the data lake,” says Peter Guerra, Principal, Booze, Allen, Hamilton. Yet, these methods are not exclusive to Booze, Allen, Hamilton.

“I have read what’s available about it,” says Dr. Stefan Deutscher, Principal, IT Practice, Boston Consulting Group, speaking of the data lake; “I don’t see what’s new. To me, it seems like re-vetting available security concepts with a name that is more appealing.” Still, the approach is gaining exposure under that name.

In fact, enterprises are showing enough interest that vendors are slapping the moniker on competing solutions. Such is the case with the Capgemini / Pivotal collaboration on the “business data lake” where the vendors are using the name to highlight the differences between the offerings.

This enterprise curiosity stems from real big data ills that need equally genuine cures. Enterprises from government agencies to large concerns and on down use big data inside public multitenant cloud environments. All the risks of mutlitenancy apply in these scenarios including the vulnerabilities that come with the weaker security of another tenant, potential access by users of an adjacent tenant, PII/PHI exposure, and other regulatory non-compliance. Data lakes could protect big data from all the perils of the public cloud.
