What mechanism is used to restrict an application's access to user or organization data in Genesys Cloud?

The correct answer is OAuth Scopes. This mechanism is essential in managing permissions in the context of application development and integration with Genesys Cloud. OAuth scopes define the specific access levels that an application has to the user's or organization's data. By using OAuth scopes, developers can limit the amount of information that an application can access and ensure that users have control over their data. This means that applications will only be able to perform actions or fetch data that have been explicitly allowed through the defined scopes.

For instance, if an application needs to read user information but doesn't require permission to delete any data, appropriate OAuth scopes can be set to only grant read access. This principle of least privilege helps in enhancing data security and compliance by ensuring that applications do not have broader access than necessary.

Understanding OAuth scopes is critical for compliance with security best practices, protecting user data, and aligning with regulatory requirements.
