SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill prevents data leakage between tenants in a multi-tenant application by enforcing strict data isolation at the database and application levels.

Core Features & Use Cases

  • Row-Level Security (RLS): Implements PostgreSQL RLS policies to filter data based on tenant context.
  • Application-Level Context: Manages tenant context within API requests and transactions.
  • Automated Testing: Includes comprehensive tests to verify tenant isolation and prevent cross-tenant access.
  • Use Case: In a SaaS application, ensures that User A from Tenant X cannot access or modify data belonging to User B from Tenant Y.

Quick Start

Ensure Row Level Security is enabled and configured for all relevant tables in your PostgreSQL database.

Frequently Asked Questions about multi-tenant-safety-checker

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent cross-tenant data leaks in a SaaS application using PostgreSQL?▼

To prevent cross-tenant data leaks, you enforce multi-tenant data isolation using PostgreSQL Row Level Security (RLS) policies and application-level context management. This ensures users in one tenant cannot access or modify data belonging to another tenant.

How does Row Level Security work for multi-tenant database isolation?▼

Row Level Security (RLS) works by implementing database policies that automatically filter data based on the current tenant context. This strictly secures SaaS application data by ensuring queries only return rows belonging to the active tenant.

What is the best way to manage tenant context during API requests for SaaS security?▼

The best way to manage tenant context for SaaS security is through application-level context management within API requests and transactions. This middleware implementation pairs with PostgreSQL RLS to enforce strict data segregation.

Do I need to modify my database schema to enable tenant isolation policies?▼

Yes, enabling tenant isolation policies requires database schema modifications to configure PostgreSQL Row Level Security on relevant tables. You also need middleware implementation and automated testing to validate the isolation policies.

How can I automatically test tenant isolation to ensure regulatory compliance?▼

You can automatically test tenant isolation by running comprehensive tests that verify cross-tenant access is blocked. This automated testing validates RLS policies to ensure regulatory compliance for data segregation.
