Docker releases hardened container images with no known vulnerabilities

• Docker expanded its Hardened Images catalog to include Alpine and Debian packages, which are foundational software layers used to build containerized applications.
• The hardened images include security patches even after the original software creators stop maintaining them, extending protection beyond typical support windows.
• Docker AI Governance, a tool for managing automated agent decisions, now logs those decisions to Docker Cloud and sends records to SIEM systems, which are security monitoring platforms.
