What Happened?

There were rumors in some local communities that the hospital was selling patient data. These occurred after there seemed to be a trend with certain lawyers using private medical history against people in insurance disputes. Security did notice the same lawyers present anytime certain types of incidents and cases came into the emergency room. IT also noticed that some unauthorized portable devices were reading and writing data.


IT performed an audit of their access logs of personal health records of patients.After an analysis cross with other systems, they were able to conclude that specific EMTs had been copying data onto flash drives while the patient was in transit to the hospital. The EMTs were tipping off some lawyers and selling personal health records to the lawyers upon arrival to the emergency room. In response to this IT coordinated with upper management to develop a baseline behavior pattern and automate alerts of deviation in user behavior. Additionally they were able to block the third party EMT vendor’s access and only allow access to records by manual approval.
