Final answer:
To securely configure the PowerShell Web Access Gateway, it is essential to secure the IIS website with SSL certificates which provide encryption for data transfer.
Step-by-step explanation:
Configuring the PowerShell Web Access Gateway is indeed a technical process where you set up the Integrated Information Services (IIS) to associate the gateway web application (known as pswa) with a particular website. This configuration process is crucial to ensure the secure access of PowerShell commands through a web interface. To secure the website effectively, it is standard practice to use SSL (Secure Socket Layer) certificates. SSL certificates help in encrypting the data transferred between the client and the server, making it difficult for unauthorized parties to intercept and understand the information.
