C5 (Germany) C5-OPS-23: Managing Vulnerabilities, Malfunctions and Errors - System Hardening

Harden production system components to generally accepted industry standards, document the hardening requirements for each component, verify immutable images against those requirements when the images are created, and retain configuration and log files evidencing their continuous availability.

Other controls in C5: Operations

You are reading one control. How much of C5 (Germany) have you already done?

C5 (Germany) C5-OPS-23 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of C5 (Germany) your existing evidence covers. Hold Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 and 95 of 121 C5 (Germany) controls already carry evidence.

If you hold Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.178.5% covered · 26 gapsIf you hold NIST SP 800-53 Rev 572.7% covered · 33 gapsIf you hold FedRAMP Moderate71.1% covered · 35 gapsIf you hold ISO 27002:202267.8% covered · 39 gapsIf you hold ISO 27001:202257% covered · 52 gapsIf you hold NIST SP 800-171 Rev 350.4% covered · 60 gaps

Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 0 were rejected on the Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 pair alone.
