2.9.6 Data Integrity for Task-Based Management
Task/command-based WM protocols can use either HTTP or HTTPS as a transport. HTTP provides no protection against eavesdropping, and it is recommended not to be used to transport confidential information.
The Windows security model handles security for resources that are accessed by using PSRP and WSMV in a task-based approach. This resource security is applicable between the command execution engine and the managed objects, as described and illustrated in section 2.9.
