Big data security is a constant concern because Big Data deployments are valuable targets to would-be intruders. A single ransomware attack might leave your big data deployment subject to ransom demands. Even worse, an unauthorized user may gain access to your big data to siphon off and sell valuable information. The losses can be severe. Your IP may be spread everywhere to unauthorized buyers, you may suffer fines and judgments from regulators, and you can have big reputational losses.
