Re: you'd assume the EMR data is encrypted
@tmerrem945: sensitive data that leaves a private network should be encrypted.  Data kept within a private network might be encrypted - but anyone (real person or system/application process), that needs access to those data values, has to have the means to decrypt that data. 

So, if an attacker has acquired the necessary credentials,  they'll have the access privileges that go with those credentials. 

Post breech forensics might be able to determine if the attacker used stolen credentials - but that can take time; and breech notification requirements don't always leave enough time for a complete investigation.

you'd assume the EMR data is encrypted
It troubles me that the hospital cannot confirm if the data was taken or viewed.  Had the data been encrypted, then they can be certain the intruder wasn't able to view the information.

Incorporating a Prevention Mindset into Threat Detection and Response
Threat detection and response systems, by definition, are reactive because they have to wait for damage to be done before finding the attack. With a prevention-mindset, security teams can proactively anticipate the attacker's next move, rather than reacting to specific threats or trying to detect the latest techniques in real-time. The report covers areas enterprises should focus on: What positive response looks like. Improving security hygiene. Combining preventive actions with red team efforts.
