After 15+ years building medical device software, I've learned something
counterintuitive: FDA regulations don't slow down secure development—they
accelerate it. For as long as I've been a Software Engineer, I've thought about
the things that can and will go wrong in software, and what the security
implications could be.
The modern view of this is called "DevSecOps". This is short
for Development, Security, and Operations, a software
engineering culture and practice that integrates security
into all phases of the software development lifecycle, promoting a culture of
shared responsibility for security.
If you think about how this point-of-view maps to the world of regulatory
compliance for medical devices and software, there are fundamentals that are
key for both. For instance, ISO62304 and the DevSecOps are concerned with
Hazard Analysis and Threat Modeling respectively, as well as requiring
traceability and auditing capabilities as foundational for risk management. The
emergence of DevSecOps has driven a welcome "left shift" of
cybersecurity into the software development cycle, making security part of
requirement and design. This is getting teams to think about security earlier
and not consider it a "bolt-on" activity. The regulatory requirements
actually enhance DevSecOps.
For Instance: Paying attention to the software manifests and SBOM from the
start can help drive conversations such as "Do we really need that
library?", "What vulnerabilities does the library have?" and “Do
we really need 47 dependencies for one feature?”. If you have to answer these questions at
deployment, without having given them prior consideration, it is a painful,
rushed and more error-prone process than it needs to be. An SBOM that meets FDA
guidelines is going to support good vulnerability management practices.
Lastly, the testing required for medical devices usually exceeds the
scope and depth of testing done solely for cybersecurity. It's not a question
of either/or but both for a successful deployment/release.
