What actions should be taken to restrict third-party applications' access to G Suite data?

The answer focuses on a proactive approach to managing third-party applications' access to G Suite data by whitelisting trusted applications and restricting API scopes. Whitelisting trusted apps ensures that only verified and secure applications gain access to sensitive data, minimizing the risk of data breaches or misuse.

By restricting API scopes, organizations can limit the extent of data an application can access, providing an additional layer of security. This means that even if a trusted application is granted access, it will only have permissions for the specific data and functionalities necessary for its operation. This granular control helps protect sensitive information while still leveraging the functionality that approved applications provide.

This comprehensive strategy is essential for maintaining data integrity and security, forming a critical element in an organization's security practices concerning third-party applications.
