Cyber Safe Data Repositories

Abstract

Nowadays, data is the center point of source to make any business decisions. With the advancements in digital technologies, business organizations gather a large amount of data using different sources. A large amount of data generation is often termed as Big Data and characterized by many V’s indicating their volume, variety, velocity, etc. Organizations use different tools to store and manage these data, and a data repository, such as a data warehouse, data lake, data mart, or data cube, is usually used. Therefore, data repositories are the source of data management and analytics, which are the collection of multiple databases in a structured or unstructured format. While data repositories benefit organizations’ large collection of data for business analytics, the question comes to cyber safety and security. Without an appropriate cyber security measure, critical data from the repositories may have unauthorized access—leading to business interrupting financial loss and possible business closer. In this book chapter, the vulnerable issues to the data repositories are discussed, and provided measures for making cyber safe data repositories.
