Security in Big Data

Abstract

Big data gained popularity in the recent decades, and it contributed to several application domains, where it changes the shape of an existing business; each and everything related to the analysis was brought in before us in a different manner. For ages, individuals have used Google to ask questions, such as applications of big data in businesses to prosper, how it can assist an organization with succeeding, which technologies of big data are favoured for this purpose, and several other related questions. A great deal has been said and written already about big data; however, the term itself stays unexplained. To be fair, we don’t agree with a prevalent definition of it being “big data means it's big in size”. This idea brings up another query of how big it is and how to measure it; is it in a terabyte, petabyte, or even more? So, to resolve this ambiguity, a need to define big data arises. The hype of big data is based on its applications and providing solutions to different complex issues. However, the security remains always a major concern, specially in case of data. The organizations are concerned for the security issues in big data as well, at the same time. This chapter will elaborate the security concerns with big data.
