Disgruntled Dave Snoops Your Healthcare Records

Posted August 17, 2011    Peter McCalister

I introduced you to Disgruntled Dave as an archetype for the type of insider villain who may already be infiltrating your extended enterprise a couple of weeks ago and guess what? Almost every day I see an article that represents “Dave” as manifesting in another company with some measurable harm that was newsworthy.

The latest article I found was at HealthcareInfoSecurity.comand showed that “Survey: Insider Threats #1 Concern.” and reported that “early results from the Healthcare Information Security Today survey shows that insider threats, such as records snooping and ID theft, are perceived to be the most significant security threats to healthcare organizations.
So it’s not surprising that, so far, the most frequently mentioned information security investment priority for the fiscal year ahead is audit logs/log management, which can be used to detect insider threats.”

What should be scary to the average healthcare consumer is that every detail of your personal information is completely available to the systems admin of your healthcare provider’s patient records system. Whether these are local to the healthcare provider’s office or stored out in the cloud, someone with full administrative privilege to that system can ultimately do whatever they want with your healthcare records, including:
copying for sale, blackmail or intimidation purposes
editing for malicious intent
deleting for covering their tracks on mismanaged care.
As we have repeatedly shown here, implementing a least privilege solution is the best way to mitigate this potential misuse of privilege and invasion of privacy.

The vulnerability lies within the various gethostbyname*() functions and, as such, has been dubbed “GHOST.” GHOST is particularly nasty considering remote, arbitrary code execution can be achieved.

Your New Years Resolution: Controlling Privileged Users

Posted January 27, 2015    Dave Shackleford

Is 2015 the year you get a better handle on security? The news last year was grim – so much so, in fact, that many in the information security community despaired a bit. Really, the end-of-the-year infosec cocktail parties were a bit glum. OK, let’s be honest, infosec cocktail parties are usually not that wild…
