What is Big Data? (Wikipedia)
Big data
Data sets so large or complex that traditional data processing applications/infrastructure are inadequate.
Challenges
include analysis, capture, curation, search, sharing, storage, transfer, visualization, and information privacy.
The term often refers simply to the use of predictive analytics or other certain advanced methods to extract value from data,
and seldom to a particular size of data set.

The CSA Big Data WG Big Data Working Group (BDWG)
Identifying scalable techniques for data-centric security and privacy problems.
Goals:
Crystallize best practices for security and privacy in big data,
Help industry and government in the adoption of best practices,
Establish liaisons with Standards Development Organizations (SDOs) to influence big data security and privacy standards
Accelerate the adoption of novel research aimed to address security and privacy issues.
