PowerShell is a powerful tool for managing Windows environments, but with great power comes great responsibility. Because it can modify system settings, access sensitive data, and execute remote commands, properly managing security within your PowerShell scripts and environment is absolutely critical. Windows enforces execution policies to control how (or if) scripts can run, and offers cmdlets for auditing, managing file permissions, and monitoring user activity.
Security-minded admins use PowerShell not just for automation, but to detect threats, limit risky behavior, and enforce compliance across their networks. From checking script execution policies to reviewing event logs and setting precise file ACL permissions, PowerShell can lock down a system, audit suspicious activity, and even manage Windows Defender. Learning these core security commands and practices makes your scripts safer and your systems harder to breach.
