Data Masking configuration for API specific level permission is not working

Google Cloud Apigee
1

Our administrator gave developers permission for data masking on organization level and on api level. However I still get 403 forbidden on the api level masking configuration. The organization level configuration is working.

I checked the permission reference sheet

https://docs.apigee.com/api-platform/system-administration/permissions#data-masks

It has the path

/applications/*/maskconfigs

It seems different from the API provided in the documentation

https://docs.apigee.com/api-platform/security/data-masking

which has the path

[https://api.enterprise.apigee.com/v1/o/{org_name}/apis/{api_name}/maskconfigs](https://api.enterprise.apigee.com/v1/o/{org_name}/apis/{api_name}/maskconfigs)

Show the exact permissions you have on the role, please?

I’m one of the Developers. I’m not the admin. Is there a way to get my permissions? Anyway what he has given me is data-masks permissions for both organizational level and api level.

I contacted him and he just said that he has given me access to everything related to data masks. Could this be a bug? knowing that permission reference has a different API than what is actually needed?

Hi @Ghassan Barghouti,

Firstly, the term applications in the resource permissions applies to apis in the Edge API URL, that’s a historical artifact.

Secondly, there appears to be an issue with maskconfigs and custom roles at the API Proxy level.

I created a custom role AllowMaskconfig and set the following permissions which did not work.

{
    "resourcePermission": [
        { "path": "/maskconfigs", "permissions": [ "get", "put" ] },
        { "path": "/maskconfigs/*", "permissions": [ "get", "put", "delete" ] },
        { "path": "/applications/features-v1/maskconfigs", "permissions": [ "get", "put" ] },
        { "path": "/applications/features-v1/maskconfigs/*", "permissions": [ "get", "put", "delete" ] }
    ]
}

Then, I tried this, which did work.

{
    "resourcePermission": [
        { "path": "/maskconfigs", "permissions": [ "get", "put" ] },
        { "path": "/maskconfigs/*", "permissions": [ "get", "put", "delete" ] },
        { "path": "/*/features-v1/maskconfigs", "permissions": [ "get", "put" ] },
        { "path": "/*/features-v1/maskconfigs/*", "permissions": [ "get", "put", "delete" ] }
    ]
}

If you assign this role to a user in the built-in User role, that user will now be able to create maskconfigs at the proxy level just for the features-v1 proxy. And if you change that path element to *, they can create maskconfigs for all proxies.

You can prevent access using a DisallowMaskconfig role with these permissions.

{
    "resourcePermission": [
        { "path": "/maskconfigs", "permissions": [] },
        { "path": "/maskconfigs/*", "permissions": [] },
        { "path": "/*/*/maskconfigs", "permissions": [] },
        { "path": "/*/*/maskconfigs/*", "permissions": [] }
    ]
}

Always fun playing with custom roles!

Thank you. I guess apigee team need to change that documentation since it is misleading. when /apis/*/maskconfigs were given as a permission it worked. /applications didn’t although it said in the documentation that this is what needs to be given to get access for mask configs.
