Technical Deep Dive

Running Postgres on AWS RDS means you are delegating the OS and hardware security to Amazon, but the 'data layer' remains your responsibility. DBX identifies common RDS hardening failures, such as insecure 'rds_superuser' usage, misconfigured parameter groups that weaken SSL enforcement, and internal system tables that are accidentally exposed to public roles.

Audit Checklist

Verify 'force_ssl' is enabled in RDS Parameter Group

Audit memberships of the 'rds_superuser' role

Check for exposed AWS-specific system tables

Validate that VPC-only access is supplemented by DB-layer RLS

Audit storage encryption status for sensitive schemas

How it works

High-integrity schema introspection

Introspect

Run a read-only script to extract your database catalog. No data ever leaves your machine.

Simulate

Our engine executes billion-path simulations to find logical RLS bypasses.

Remediate

Receive copy-paste SQL fixes for every high-risk vulnerability discovered.
