Hi Thejaka, Yes, that makes sense. For a bit more context: if you are familiar with the existing GatewayResourceProfile, then you’ll find the GroupResourceProfile very similar. We’re transitioning from a GatewayResourceProfile that is implicit shared with all gateway users to a model where there are one or more GroupResourceProfiles that define a set of compute resources that each are shared with one or more groups.
I agree with your assessment. I think we can solve this problem by attaching permissions to the credential store tokens.

I don't have a better understanding of the functionality provided by "GroupResourceProfiles". However, based on your description I understood the following: "GroupResourceProfiles" has some sensitive details that belong to the current (user: A) user. Another user (user: B) can clone "GroupResourceProfiles" with these sensitive details and can use authentication/ authorization data from user A. In my opinion, when cloning "GroupResourceProfiles" to user B space all the fields that contain sensitive data should be nullified or fill them with appropriate data for user B (e.g., credential store tokens belonging to user B). I believe we need to do this for all authentication data in "GroupResourceProfiles" irrespective of the permission action (READ, WRITE) attached to "GroupResourceProfiles". It sounds like "GroupResourceProfiles" is an abstract field which contains several concrete data fields. In that case, we can handle this in a more general way by attaching permissions to those concrete data fields. Hope this makes sense.

The problem is this: any user that has READ access to a GroupResourceProfile can effectively clone that GroupResourceProfile. This would allow the user to create a new GroupResourceProfile that uses the same login/allocation and this new GroupResourceProfile could have fewer restrictions or be shared with other users. Here are some solutions I’m considering: 1. Create a new permission type that is less privileged than READ and that gives access to less details. There are a few details in the GroupComputeResourcePreferences that are sensitive, like loginUserName, resourceSpecificCredentialToken and allocationProjectNumber, because these fields determine what account gets charged and these could be left out. 2. Hide the sensitive fields mentioned above from users with READ access and only show them to users with WRITE access. 3. Apply group based authorization to credential tokens and require new GroupResourceProfiles to have their own credential tokens, that would only be accessible to the user that creates the GroupResourceProfile. I’m open to other ideas. I’m leaning toward #2. The problem with #1 is it introduces another permission type (READ, WRITE and “USE”?) that will complicate the user experience. #3 also complicates what is required to create a GroupResourceProfile. One use case we have in mind is that users who create a GroupResourceProfile can leverage defaults defined in the GatewayResourceProfile and thus only need to provide an allocation project number and not need to add an SSH key to a compute resource account. Approach #3 would make that more difficult or impossible. I hope the above makes sense. Let me know if you have any questions. Thanks, Marcus
