## Operating systems

The current catalog includes listings based on CentOS, Oracle Linux, Red Hat Enterprise Linux, Rocky Linux, Amazon Linux, and Debian. Availability varies by product profile, version, and processor architecture.

## Important scope boundary

References to hardening guides, framework profiles, or compliance describe product-specific operating-system scope. A hardened image is one layer of a larger system. Buyers remain responsible for application configuration, identity, networking, monitoring, evidence, ongoing operations, and determining whether the complete system satisfies their security or regulatory obligations.
