Scattered data storage and access patterns have created a scenario where enterprise information is under constant threat from internal and external actors. It’s up to the CISO to design, develop, and implement a solution that secures big data and drives business value across the organization. The CISO must also be able to justify the big data security plan to the Board and obtain critical stakeholder buy-in.
