When we look at today's big data offerings, such as Ranger and Sentry, nothing comes close to answering this call. Even solutions for RDBMS-based systems tend to be proprietary, expensive, and often incomplete. Organizations doing high security with complex security rules are forced to implement this on their own. Heck, data tagging tools are still in their infancy for big data systems like Hadoop.
In other words, there's a big opportunity here for the vendors who can figure it out. Clearly, the defense industry is the first customer, because it's already doing it out of necessity. As more companies create central data repositories for big data analysis, the need for policy-based security is only going to grow.
