Reference CIS Benchmark controls with audit and remediation commands for Linux (Ubuntu and Debian), Docker, Kubernetes, and AWS Foundations, plus hardening automation and a prioritization framework. Use when hardening a system or checking a configuration against CIS controls.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CIS Benchmarks > Reference knowledge base for CIS Benchmark controls across common platforms: Linux, Docker, Kubernetes, AWS, PostgreSQL, Nginx, and more. ## Knowledge Base ### CIS Benchmark Structure Every CIS Benchmark follows a consistent structure: - **Profile Levels**: Level 1 (practical, minimal impact) and Level 2 (defense-in-depth, may impact functionality) - **Scored vs Not-Scored**: Scored controls count toward compliance percentage. Not-scored controls are recommendations. - **Control Format**: Each control has a description, rationale, audit procedure, remediation procedure, and impact statement - **Assessment Status**: Automated (can be checked with tools) or Manual (requires human judgment) ### Linux (Ubuntu/Debian) -- Key Controls #### 1. Initial Setup **1.1 Filesystem Configuration** ```bash # Ensure /tmp is a separate partition with nodev, nosuid, noexec # Audit: mount | grep -E '\s/tmp\s' # Expected: /tmp on separate partition with nodev,nosuid,noexec # Ensure /var, /var/tmp, /var/log, /var/log/audit are separate partitions # Audit: mount | grep -E '\s/var\s' # Disable unused filesystems # /etc/modprobe.d/CIS.conf: install cramfs /bin/true …

How to install
mdr add hermeticormus/libresecops-claude-code/cis-benchmarks@sha256:dbaa9f333a798b31The line at the top of this page pins the label git:20260930.71a2663, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
