Warner demands answers following exposure of medical data belonging to servicemembers
U.S. Sen. Mark Warner, D-Va., has urged the Defense Health Agency to remove sensitive medical data belonging to servicemembers exposed online, where it remains vulnerable due to insecure data practices at Ft. Belvoir Medical Center, Ireland Army Health Clinic, and the Womack Army Medical Center.
“As a matter of national security, the sensitive medical information of our men and women of the armed services is particularly vulnerable and should be, at a minimum, protected by robust security controls and routine scans,” wrote Sen. Warner. “The exposure of this information is an outrageous violation of privacy and represents a grave national security vulnerability that could be exploited by state actors or others.”
He continued, “We owe an enormous debt to our armed forces, and at the very least, we ought to ensure that their private medical information is protected from being viewed by anyone without their express consent. Whenever data moves from one entity to another it should be protected by encryption, proper hashing, segmentation, identity and access controls, and vulnerability management capabilities that include diligent monitoring, auditing, and logging practices.”
In September, Sen. Warner sought answers from TridentUSA Health Services regarding reports that many unsecured picture archiving and communication servers (PACS) left the names, dates of birth, medical images, and medical procedures of more than one million Americans accessible to anyone with basic computer expertise. Following that letter, the images were removed but millions of records were left online.
Nearly two months later, Sen. Warner called out the U.S. Department of Health and Human Services (HHS) for its failure to act following the exposure.
Since the letter to HHS, 16 systems, 31 million images and 1.5 million exam records have been removed from the internet. However, a significant number of personally identifiable and sensitive medical information belonging to servicemembers remains online, due to unsecured Army PACS.
In his letter to the Assistant Secretary, Sen. Warner asked the agency to remediate the situation immediately and posed the following questions for Assistant Secretary Thomas McCaffery:
- Please describe the information security management practices at military medical hospitals. Do you require organizations to operate on a segmented network? To implement micro-segmentation? To implement access controls? If so, what kind? Do you require the hospitals to implement multifactor authentication, logging, and monitoring?
- Do you audit and monitor logs?
- Do you require full-disk encryption and authentication for PACS?
- Do you require the hospitals to have a Chief Information Security Officer?
- Please describe what steps you took to address this issue, and when you were able to remove these systems from the internet.
