Explore the evolution of platform security measurement in Linux through this 25-minute conference talk examining the LVFS Host Security ID (HSI) standard and its implementation challenges. Learn how HSI has become the de facto standard for measuring platform security across major Linux distributions, while discovering the unique edge cases that arise when working with open-source firmware vendors using diverse firmware stacks like coreboot and edk2. Analyze current platform security measurement approaches across different operating systems and investigate opportunities to enhance Linux's implementation through potential kernel API extensions. Gain insights into simplifying and unifying the assessment of advanced security features including Static Root of Trust for Measurement (SRTM) and Dynamic Root of Trust for Measurement (DRTM), while understanding the broader implications for platform security in the Linux ecosystem.
