📊 Data Architecture and Security

Overview

This document outlines GetCimple's data architecture, security controls, and privacy measures to ensure the protection of sensitive compliance and governance information.

Key Documents

Core Principles

  • Zero-trust security model
  • Multi-tenant isolation by design
  • Data minimization and purpose limitation
  • Encryption at rest and in transit

Data Storage Architecture

Primary Storage

  • Platform: Supabase (PostgreSQL)
  • Isolation: Row-level security (RLS) policies
  • Backup: Automated daily backups with point-in-time recovery

Edge Storage

  • Platform: Cloudflare Workers KV
  • Purpose: Session data and caching
  • Retention: Time-limited with automatic expiry

Security Architecture

Authentication & Authorization

  • Provider: Kinde Auth
  • Model: RBAC with tenant isolation
  • Sessions: JWT with short expiry times

Encryption Standards

  • At Rest: AES-256 encryption
  • In Transit: TLS 1.3 minimum
  • Key Management: Automated rotation

Data Classification

Sensitivity Levels

  1. Public: Marketing content, general information
  2. Internal: Business processes, non-sensitive operational data
  3. Confidential: User data, compliance records
  4. Restricted: Security credentials, audit logs

Privacy Controls

GDPR Compliance

  • Right to access implementation
  • Right to deletion procedures
  • Data portability mechanisms
  • Consent management

Australian Privacy Principles

  • Transparent collection notices
  • Purpose limitation enforcement
  • Cross-border transfer controls
  • Breach notification procedures

Access Controls

Role-Based Access

  • Director read-only views
  • Implementation team full access
  • Admin configuration rights
  • Auditor inspection access

Audit Logging

  • All data access logged
  • Immutable audit trail
  • Regular access reviews
  • Anomaly detection

Data Lifecycle

Retention Policies

  • Compliance records: 7 years
  • Audit logs: 2 years
  • Session data: 24 hours
  • Backup data: 30 days

Secure Deletion

  • Cryptographic erasure
  • Multi-pass overwriting
  • Certificate of destruction
  • Backup purging

Incident Response

Data Breach Protocol

  1. Immediate containment
  2. Impact assessment
  3. Stakeholder notification
  4. Remediation actions
  5. Post-incident review

Future Enhancements

  • Advanced threat detection
  • Homomorphic encryption exploration
  • Zero-knowledge proof implementation
  • Quantum-safe cryptography preparation
