Big Data can mean big problems in managing data access, the perennial balancing act of providing unencumbered access to those with “need to know” and shielding information from everyone else.  Big data platforms such as Hadoop are notoriously primitive in their access controls.  In this session, we’ll examine some of the technologies and processes Dell uses to secure big data on a variety of platforms while still enabling discovery and analytics, and the harnessing of big data for innovative solutions for Dell Technologies.
