About this tag
The vex tag on WindowsForum.com covers discussions about Vulnerability Exploitability eXchange (VEX) documents, particularly in the context of Microsoft Azure Linux and software supply chain security. Topics include Microsoft's VEX/CSAF attestations for Azure Linux, the relationship between VEX and Software Bill of Materials (SBOM) transparency, and CISA's efforts to standardize SBOM and VEX practices globally. Recurring themes involve inventory gaps in published VEX documents, the role of VEX in vulnerability management, and the push for automated, machine-readable software transparency across government and industry.
