Prüfliste für die Grundabsicherung eines eigenen Laptops oder PCs unter Windows, macOS und Linux: Updates, Schutzprogramm, Firewall, Festplattenverschlüsselung, Konten und Rechte, Fernzugänge, Startkette. Je Punkt eine schreibgeschützte Prüfung und ein Soll; Änderungen nur nach Backup und einzelner Bestätigung. Defensiv, für den Privatgebrauch gedacht, kein Ersatz für Vorgaben einer verwaltenden IT.
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
<img src="banner.png" width="100%" alt="os-hardening-baseline banner"> # os-hardening-baseline (Deutsch) Eine Grundabsicherung für ein **eigenes** Gerät, nach einem Vorfall oder vorbeugend. Die Liste ist ein Ziel, kein Befehl: Jede Änderung wird erklärt, vorher gesichert und einzeln bestätigt. Strukturelle Härtung ganzer Software-Projekte gehört nicht hierher, sondern zu `sec-hardening`. **Vorgehen:** erst nur prüfen (alle Prüfbefehle lesen nur), Abweichungen in `incident-notes` oder einer Fallnotiz sammeln, danach mit der Eigentümerin oder dem Eigentümer entscheiden, was geändert wird. Manche Befehle brauchen Administratorrechte; die Rechte nur für die einzelne Prüfung nutzen. Geräte, die eine Firma oder Schule verwaltet, nicht verändern. ## Windows | Punkt | Prüfung (lesend) | Soll | |---|---|---| | Updates | Einstellungen, Windows Update; `Get-HotFix` | aktuell, automatische Updates an | | Schutzprogramm | `Get-MpComputerStatus` (Felder `AntivirusEnabled`, `RealTimeProtectionEnabled`) | aktiv, Signaturen aktuell | | Firewall | `Get-NetFirewallProfile \| Select Name, Enabled` | alle Profile an | …

How to install
mdr add ellmos-ai/skills/os-hardening-baseline@sha256:3cf88b02084e845dThe line at the top of this page pins the label v1.0.0, 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.
