Just Enough Administration (JEA) is a security technology that enables delegated administration for anything managed by PowerShell. JEA helps in reducing the number of administrators on your machines by using virtual accounts or group-managed service accounts to perform privileged actions on behalf of regular users. It limits what users can do by specifying which cmdlets, functions, and external commands they can run. This ensures that users have just enough access to perform their jobs without having unnecessary administrative privileges, which aligns with the principle of least privilege123.
