CIS RHEL 9 Benchmark, continuously evidenced.
The CIS Red Hat Enterprise Linux 9 Benchmark defines 296 security controls covering filesystem hardening, services minimization, network configuration, logging and auditing, access control, SSH hardening, SELinux, and DNF package management. CISGuard's agent-based scanning evaluates every control with per-host evidence and historical posture trending.

Red Hat Enterprise Linux 9 questions, answered directly.
Does CISGuard support RHEL 8 and earlier?
Yes. CISGuard supports RHEL 9, 8, and 7 with the corresponding CIS benchmarks. CentOS, Rocky Linux, AlmaLinux, and Oracle Linux are detected as RHEL-derivatives and scan against the matching RHEL benchmark version.
How does CISGuard handle SELinux state?
CIS RHEL 9 Benchmark requires SELinux in Enforcing mode by default. CISGuard reports the current SELinux state per host. Permissive or Disabled states are flagged as control failures, and the exception management workflow documents any approved deviations with compensating controls.
Can CISGuard scan RHEL containers and immutable images?
Yes. CISGuard supports RHEL container images and immutable RHEL CoreOS deployments. For ephemeral container infrastructure, CIS posture evaluation runs at image-build time as part of CI/CD; for long-running RHEL hosts, the scanning agent runs as a systemd service.
