There are ways for healthcare organizations to protect the electronic health records (EHR) of their patients. But a segregated network for EHR is generally not one of them, says Martin Fisher, director of information security for Atlanta-based Wellstar Health System.

Fisher disputes a recommendation for segregated networks by Robert Hudock, a lawyer and certified "ethical hacker" cited yesterday in CSO Online's story on the epidemic of healthcare data breaches.

Hudock's first recommendation to protect EHR, made in an interview last May with FierceEMR, is to keep them on a segregated network "if at all possible."

In that interview, Hudock said the Veterans Administration (VA) segregated its EHR after suffering significant infections, and improved its security significantly.
