Windows - Security Fundamentals

Windows Security

script execution policy - determines what types of scripts PowerShell can execute. For Windows clients running PowerShell 5.1, the default is Restricted, which blocks all scripts from running unless they are signed with a trusted certificate. Change the execution policy to RemoteSigned - this execution policy allows the user to run unsigned PowerShell scripts if they’re created locally but will not allow us to execute unsigned scripts downloaded in a web browser or attached to emails.
