re: Leveraging Big Data to Revolutionize Fraud Detection
Big data techniques can also be used to in intrusion/cyberattacks detection & prevention, customer online access & usage behavioral analytics, AML, KYC, etc.
As you were eluding to in the article above, I would also advise firms to think about overall governance and its applicability to big data.
Frequently firms apply more stringent or similar governance standards to big data solutions than what is in place for traditional solutions. In order to be successful with big data, IT/Business need to engage internal risk, governance, audit, security teams early on and work with them to develop governance standards that are relevant to the company.
