Final answer:
The security measures, including a security certificate from a trusted certification authority and user-specific authorization rules, are crucial for the security configuration of the Windows PowerShell Web Access gateway server.
Step-by-step explanation:
The security measures of employing a security certificate from a trusted certification authority and user-specific authorization rule are crucial for the security configuration of the Windows PowerShell Web Access gateway server.
Firstly, using a security certificate from a trusted certification authority ensures that the communication between the gateway server and the clients is encrypted and secure. This prevents unauthorized access or interception of sensitive information.
Secondly, user-specific authorization rules help enforce access control policies, allowing only authorized individuals to access the gateway server and perform specific actions. This ensures that the system remains protected from unauthorized or malicious activities.
