🚨 Harden your Windows systems using free, trusted open-source tools that cover audit, configuration, and monitoring. You don't need enterprise tools to raise your defense baseline — just a few solid steps.
Quick Actions (Under 30 Minutes):
• Run Hardentools — disable unsafe defaults instantly.
• Use CIS-CAT Lite — identify missing patches, open RDP, or weak policies.
• Check Local Admins — remove unused accounts, deploy LAPS for password rotation.
• Turn On Logging — enable PowerShell, Windows Defender, and Audit Policy logs.
• Run WinAudit — export a report and compare it weekly for unauthorized changes.
• Scan with Wazuh or OpenVAS — look for outdated software or exposed services.
Key Risks to Watch:
🔑 Reused or shared admin passwords
🌐 Open RDP/SMB without firewall or NLA
⚙️ Old PowerShell versions without logging
🧩 Users running with local admin rights
🪟 Missing Defender Attack Surface Reduction (ASR) rules
📦 Unpatched or unsigned software from third-party repos
