Firebase Security Rules provide access control and data validation
in a simple yet expressive language. They are used to secure products
such as Cloud Storage and Cloud Firestore.
This documentation is divided into two sections:
Interfaces - data types common to all
products that use Security Rules.
Namespaces - data types and functions
that are product or context specific.
