Provide control over who can use the SNODEID parameter

This idea was previously raised for CDz CONDIRECTZ-I-8, however, it was informed by CDz L3 that the enhancement in CDz will not be able to work on remote Distributed CD nodes. Therefore, this request is raised for similar function on distributed platforms. Details of the requirement is a below:

With SPOE, the SNODEID presents a security vulnerability. The SNODEID is hard-coded in the process in clear text. Anyone authorized to use CDZ and able to read the file where the SNODEID is coded, typically in the process library, can create and submit their own process and have access on the remote node granted to the SNODEID under SPOE. Knowing the SNODEID a malicious actor could:

• Retrieve the same production data that was sent by the local node to the remote node.

• Retrieve the same production data that was or will be sent by the remote node to the local node.

• Send bogus data from the local node to a production file on the remote node.

To mitigate this risk, we would like to have the capability to limit the use of the SNODEID by the user ID (ACID) submitting the process. A given ACID would need to be permissioned to use a particular SNODEID for a particular remote node. If the ACID were not correctly permissioned, then the process submit should fail. Ideally, the management of ACID permissions to use SNODEID's would be handled through the ESM (enterprise security manager) allowing proper separation of responsibilities between CD administrators and engineers and security administrators.
