Horst Herb of the GNUmed project has written an essay on tampering with Electronic Health Records (EHR) and how vendors can claim they are secure when they are not: ‘…I will now demonstrate one by one how…naive countermeasures can be circumvented. Most software vendors are of course using a combination of…measures in the naive attempt to make it more difficult to “hack”. All they achieve is wasting a little more of a “hackers” time…’ Comments are welcome.
