Security Features of PowerShell 7 with Mike O'Neill

About this episode

How secure are your PowerShell scripts? Richard talks to Mike O'Neill about the powerful security features introduced with PowerShell 7.3 and above, including session configuration files and clean blocks. Mike talks about how some organizations are strict about installing anything on servers, including the latest version of PowerShell - which is one of the reasons 5.1 has persisted so long. But that ends with 26H2 and opens the door to securing your PowerShell with strict controls over accounts, cmdlets, and more! The latest PowerShell makes it easier to have just enough administration - and makes it harder for the black hats to exploit!
