That it was never created to become a security control I started alerting on it anyway at least from non-admin devices   https://www.mssqltips.com/sqlservertip/2702/setting-the-powershell-execution-policy/    Want to learn Powershell? UnderTheWire wargame: https://underthewire.tech/   Jeffrey Snover "The Cultural battle to remove Windows from Windows Server": https://www.youtube.com/watch?v=3Uvq38XOark   You talk about "why would anyone want to remove powershell" as it came as a standalone download and part of the windows sdk. - I was taught when I was just getting into tech, that I should fear powershell and didn't realize how powerful it could be as an admin because of it.   Powershell slime trail "You can't force a powerful tool only to be used how you want it to be used, you can tilt the playing field on behalf of defenders"   If an attacker is going to use powershell, let's make them regret it   Powershell has had quite an impact and history.   My own sorry logging/alerting attempts   You mentioned the amount of attacks listed in MITRE that use powershell, is that *the* recommended resource for blue teamers, are there any others?   Revoke-Obfuscation white paper (blackhat2017): https://www.blackhat.com/docs/us-17/thursday/us-17-Bohannon-Revoke-Obfuscation-PowerShell-Obfuscation-Detection-And%20Evasion-Using-Science-wp.pdf   https://github.com/danielbohannon/Invoke-Obfuscation  https://github.com/danielbohannon/Revoke-Obfuscation   https://blog.trendmicro.com/trendlabs-security-intelligence/ransomware-now-uses-windows-powershell/  https://www.trendmicro.com/vinfo/us/threat-encyclopedia/malware/TROJ_POSHCODER.A    Ever thought of writing a powershell security sentric book?
