[CB24]SBOM and Security Transparency - How it all fits together

## Overview CISA's Alan Friedman (remote at Code Blue Tokyo) explains why SBOMs and security transparency are essential—and why the ecosystem is still being built mid-flight.

## Why SBOMs Matter Producers cannot claim secure development without knowing what's inside their software. Buyers need supply-chain visibility; operators need fast vulnerability response—Log4j was cheaper for organizations with SBOM coverage.

## Policy and Identifiers Regulation is coming globally. CISA advocates multiple software identifiers beyond CPE—PURLs, Software Heritage IDs, and OmniBOR—so vulnerability data maps reliably to components.

## Coordinated Disclosure Link SBOMs answer "what's in the build"; coordinated vulnerability disclosure answers "where flaws originate." Friedman urges viewers to engage CISA guidance on the software identification ecosystem.

## Takeaways SBOM adoption is shifting from best practice to compliance requirement—start generating, consuming, and operationalizing them before the next ecosystem-wide vulnerability.
