HL7 Data Interfaces in Medical Environments – Attacking & Defending the Achilles’ Heel of Healthcare

This security research served as a 2-part SANS gold paper examining the insecurities of the HL7 messaging standard. This presentation is a combination of those two papers. HL7 is arguably the most fundamental flaw in healthcare IT. It is used extensively for system-to-system communications and is in nearly every healthcare facility worldwide. The first paper is an overview of what can be done with stolen medical data, what HL7 is, as well as potential dangers inherent to HL7. The second paper moves beyond theory and is an in-depth, technical discussion on ways to attack and defend HL7.
