I recently had the privilege of interviewing Daniel Dura, CTO of Graphium Health recently on the subject of security on the frontlines of healthcare, and a few key themes emerged that I want to highlight and elaborate on below.
Regulatory compliance is necessary but not sufficient for effective security and breach risk mitigation. To effectively secure healthcare organizations against breaches and other security risks one needs to start with understanding the sensitive healthcare data at risk. Where is it at rest (inventory) and how is it moving over the network (inventory), and how sensitive is it (classification)? These seem like simple questions, but in practice are difficult to answer, especially with BYOD, apps, social media, consumer health, wearables, Internet of Things etc driving increased variety, volume and velocity (near real-time) sensitive healthcare data into healthcare organizations.
There are different types of breaches. Cybercrime type breaches have hit the news recently. Many other breaches are caused by loss or theft of mobile devices or media, insider risks such as accidents or workarounds, breaches caused by business associates or sub-contracted data processors, or malicious insiders either snooping records or committing fraud. Effective security requires avoiding distraction from the latest media, understanding the various types of breaches holistically, which ones are the greatest risks for your organization, and how to direct limited budget and resources available for security to do the most good in mitigating the most likely and impactful risks.
Usability is key. Healthcare workers have many more information technology tools now than 10 years ago and if usability is lacking in healthcare solutions or security it can directly drive the use of workarounds, non-compliance with policy, and additional risks that can lead to breaches. The challenge is to provide security together with improved usability. Examples include software encryption with hardware acceleration, SSD’s with encryption, or multi-factor authentication that improves usability of solutions and security.
Security is everyone’s job. Healthcare workers are increasingly targeted in spear phishing attacks. Effective mitigation of this type of risk requires a cultural shift so that security is not only the job of the security team but everyone’s job. Security awareness training needs to be on the job, gamified, continuous, and meaningful.
I’m curious what types of security concerns and risks are top of mind in your organization, challenges you are seeing in addressing these, and thoughts on how best to mitigate?
