DescriptionThe emerging 47‑day certificate mandate, which significantly reduces the maximum lifetime of public TLS certificates, is changing how digital certificates must be managed. For z/OS environments built around long‑running services, this shift introduces new operational and availability challenges.
This session explains what the 47‑day certificate mandate is, why it exists, and how it impacts digital certificate usage on z/OS. We will review common z/OS certificate use cases, discuss expiration risks, and highlight lifecycle management considerations involving TLS, SAF/RACF key rings, and the growing importance of automation in managing frequent certificate renewals.
