NoSQL phenomenon has taken the database and IT application world by storm. Growth and penetration of NoSQL applications, driven by Silicon Valley giants like Facebook, Twitter, Yahoo, Google and LinkedIn, has created an unprecedented database revolution, to inspire smaller companies to join the NoSQL bandwagon. While expansion and growth of these databases are adding glory and success to many corporate IT departments, it is very pertinent to explore the security aspects of these new era databases. Confidentiality, integrity and availability (CIA) are the very foundation of data protection and privacy. In this paper a sincere attempt is made to survey, analyze and assess the maturity of NoSQL databases through the lens of CIA triad. While the concept of CIA has its origins in relational databases, it is very important to understand, survey and delineate the security capabilities of this new generation databases, in terms of CIA fulfillment.
