Security Challenges in Big Data

Abstract

The biggest challenge for big data from a security point of view is the protection of user’s privacy. Big data frequently contains huge amounts of personal identifiable information and therefore privacy of users is a huge concern. Because of the big amount of data stored, breaches affecting big data can have more devastating consequences than the data breaches we normally see in the press. This is because a big data security breach will potentially affect a much larger number of people, with consequences not only from a reputational point of view, but with enormous legal repercussions. While using big data a significant challenge is how to establish ownership of information. If the data is stored in the cloud a trust boundary should be establish between the data owners and the data storage owners.
