Total Product Lifecycle Security: From Design to Disposal

How well does your security strategy cover the entire product lifespan - from concept to decommissioning?

This episode dives into the importance of the Total Product Lifecycle (TPLC) and Secure Product Development Framework (SPDF) in medical device cybersecurity. Christian and Trevor share stories, best practices, and pitfalls from real-world cases involving update security, insecure development environments, and overlooked decommissioning risks.

Key points:

(1:50) Intro to TPLC and SPDF

• The importance of TPLC and SPDF in secure development.

(7:00) Update Vulnerabilities and OTA Risks

• An example of compromised keys in an otherwise secure over-the-air (OTA) process.

• Trade-offs between update convenience and security.

(12:16) Threat Modeling

• Threat modeling’s application to development environments.

• The overlooked risks of data storage locations and natural disasters.

(17:24) Infrastructure Challenges

• How clients struggled with infrastructure across hospital environments.

• How scripts and hardcoded passwords can introduce risk.

(19:56) Building a SPDF That Works

• Best practices: coding standards, multi-layer review, and automated testing.

• Secure development is like planning for your own death - it’s hard, but necessary.
