If you want to make a cybersecurity professional uncomfortable, simply utter these two word: ‘Data exfiltration.’ Why will this term garner an emotional response? Because data exfiltration is a worst-case outcome of a cyber-attack – think Target, the NY Times, Google Aurora, Titan Rain, etc. Simply stated, ‘data exfiltration’ is a quasi-military term used to describe the theft of sensitive data like credit card numbers, health care records, manufacturing processes, or classified military plans.
Most enterprises now recognize the risks associated with data exfiltration and are now reacting with new types of security technologies, granular network segmentation, and tighter access controls. Good start but what about simply monitoring sensitive data access activities? You know, who accesses the data, how often, what they do, etc.?
