To audit Supabase Row Level Security policies and GRANT statements, run a security audit script that analyzes PostgreSQL system catalogs to generate a detailed access matrix and pinpoint missing configurations. This process identifies security gaps in your database access controls.

Common Supabase database access control security gaps include missing RLS policies for granted privileges and overly permissive table configurations. Auditing these GRANT statements helps verify that user data protection and admin access patterns are correctly restricted.

You can generate an access matrix to verify Supabase admin access patterns by auditing RLS policies against table-level GRANTs. This validates whether operations like UPDATE and DELETE are correctly restricted to authorized administrators while allowing SELECT for authenticated users.

Yes, the Supabase security audit requires execution within a Supabase environment with direct access to PostgreSQL system catalogs. This access is necessary to analyze and validate RLS policies and table-level GRANT statements comprehensively.

You should audit RLS policies to identify missing data protection rules whenever you grant new table privileges or modify user roles. This ensures that sensitive data remains protected by verifying that every granted privilege has a corresponding restrictive policy.
