SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill addresses the critical need to protect sensitive data stored in databases by implementing robust security measures against unauthorized access and breaches.

Core Features & Use Cases

  • Data Encryption: Encrypts sensitive columns (like PII) at the application level.
  • Row-Level Security (RLS): Isolates tenant data within shared tables using PostgreSQL RLS.
  • Connection Hardening: Enforces SSL and uses least-privilege database users.
  • Backup Strategy: Implements logical and physical backups for disaster recovery.
  • Audit Logging: Tracks all data changes with a dedicated audit table and triggers.
  • Use Case: For a multi-tenant SaaS application, this skill ensures that each tenant's data is isolated and encrypted, and all access is logged for compliance.

Quick Start

Implement database security by encrypting sensitive columns, enabling Row-Level Security, and setting up audit logging.

Frequently Asked Questions about Securing Data

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

FAQPage Schema
How do I isolate tenant data in a shared PostgreSQL database?▼

To isolate tenant data in a shared PostgreSQL database, you enable Row-Level Security (RLS) policies to restrict row access based on tenant context. This skill configures RLS to ensure multi-tenant SaaS applications keep each tenant's data strictly separated.

What is the best way to encrypt sensitive PII columns in PostgreSQL?▼

To encrypt sensitive PII columns in PostgreSQL, implement application-level encryption before writing data to the database. This skill secures sensitive columns by applying encryption directly within your application layer.

How do I set up audit logging for PostgreSQL data modifications?▼

You set up audit logging for PostgreSQL data modifications by creating a dedicated audit table and attaching trigger functions to your tables. This skill integrates these triggers to automatically track all data changes for compliance.

How do I enforce secure connections and least-privilege roles in PostgreSQL?▼

You enforce secure PostgreSQL connections by mandating SSL and configuring least-privilege database users. This skill hardens database connections by requiring SSL and assigning restricted roles to limit unauthorized actions.

What is included in a robust PostgreSQL backup strategy?▼

A robust PostgreSQL backup strategy includes both logical and physical backups for disaster recovery. This skill establishes a comprehensive backup routine utilizing pg_dump for logical exports and pg_basebackup for physical backups.
