CubeCOS - Release Note

Abstract​

CubeCOS 2.5 is a focused update of Bigstack’s cloud operating system with dedicated support for IEC 62443-3-3 compliance. This release introduces key security features, improved operational visibility, and enhanced platform componentsβ€”while continuing to deliver a hardened, enterprise-ready infrastructure layer.

✨ New Features​

πŸ” Security​

Disk Encryption​

  • Added encryption mode for adding new disks.
  • Each drive now defaults to one OSD for improved security granularity.

Security Scanning Integration​

  • Integrated mandatory vulnerability scanning in the build pipeline.
  • Ensures runtime packages are sourced from trusted upstream repositories and are free of known high-severity vulnerabilities.

File System Integrity Protection​

  • CubeCOS automatically detects file system modifications and restores original files when unauthorized changes are identified.

USB Device Control​

  • USB storage devices are now blocked by default to prevent unauthorized or malicious content from being introduced via USB media.
  • Admins can toggle USB access via CLI setting cubesys.probeusb. If the tuning is true, USB storage devices are accessible to CubeCOS. In the other hand, if the tuning is false, those devices are blocked from CubeCOS.
