Why PowerShell security matters
PowerShell is powerful for administration and automation, but attackers may also abuse it. Defensive configuration and monitoring help reduce risk.
Use least privilege
Do not run every script as domain admin. Use the minimum permissions required and separate daily user accounts from admin accounts.
Enable useful logging
PowerShell script block logging, module logging, and transcription can help investigate suspicious activity and troubleshoot automation issues.
Review scripts before running
Check source, purpose, commands, network connections, file operations, and privilege requirements before executing scripts from the internet.
Safe automation practices
Store scripts in a controlled repository, sign critical scripts where possible, document changes, and test in a lab before production use.

Final thoughts
Cybersecurity improves when teams make small, consistent improvements across identity, endpoints, networks, cloud systems, monitoring, and user awareness.
