Why This Security Checklist Matters

Security checklists serve as systematic guides for identifying vulnerabilities that might otherwise be overlooked during rapid development cycles. For Turso applications specifically, this checklist addresses the most common security gaps that emerge when using AI-assisted development workflows.

Research from multiple security organizations indicates that approximately 80% of AI-built applications contain at least one exploitable vulnerability at launch. The vulnerabilities are often predictable—they follow patterns that this checklist is designed to catch. By systematically reviewing each item, you significantly reduce the risk of launching an insecure application.

Unlike generic security checklists, this guide focuses specifically on vulnerabilities prevalent in Turso applications. Each item has been prioritized based on real-world attack patterns and the potential impact of exploitation. Critical items should be addressed before any production deployment.

Critical Priority

Critical items can lead to complete application compromise, data breaches, or unauthorized access to all user accounts. These must be addressed before deploying to production. Attackers actively scan for these vulnerabilities.

High Priority

High priority items represent significant security risks that could allow unauthorized access to sensitive data or functionality. While not immediately catastrophic, these vulnerabilities should be fixed as soon as possible.

Medium/Low Priority

Medium and low priority items strengthen your overall security posture. While they may not be immediately exploitable, addressing them prevents attack chains and defense-in-depth gaps.

Manual vs Automated Security Checking

While manual security reviews are thorough, they're time-consuming and prone to human error. Automated scanning catches common vulnerabilities instantly, freeing you to focus on business logic and complex security decisions.

Items VAS Automates

  • Exposed API keys and secrets in JavaScript bundles
  • HTTP security header configuration
  • Supabase RLS policy testing
  • Firebase Security Rules validation
  • Cookie security attributes

Manual Review Still Required

  • Business logic vulnerabilities
  • Custom authentication implementations
  • Access control logic in API routes
  • Data validation requirements
  • Third-party integration security

Authentication

critical

Protect database tokens

Auto

Store Turso auth tokens in environment variables, not code

high

Use scoped tokens

Create tokens with minimal necessary permissions

medium

Rotate tokens periodically

Regularly rotate authentication tokens

high

Different tokens per environment

Use separate tokens for development and production

Data Security

high

Encrypt sensitive data

Consider encrypting PII before storing in Turso

critical

Use parameterized queries

Prevent SQL injection with proper parameterization

high

Validate input at application level

Don't trust user input - validate before querying

medium

Review data replication

Understand where your data is replicated

Access Control

critical

Implement application-level access control

Turso doesn't have RLS - enforce access in your app

medium

Use separate databases for tenants

Consider database-per-tenant for isolation

medium

Audit database access

Log and monitor who accesses what data

medium

Review team member permissions

Check who has access to Turso dashboard

Edge Deployment

medium

Understand edge replica behavior

Edge replicas provide low latency but have consistency tradeoffs

medium

Configure proper regions

Choose regions appropriate for your users and compliance

low

Monitor replication lag

Be aware of eventual consistency in reads

medium

Use read replicas appropriately

Understand when to use primary vs replicas

Frequently Asked Questions

What's the difference between critical and high priority items?

Critical items represent immediate security risks that could lead to data breach if not addressed - like missing database access controls or exposed secrets. High priority items are important but typically require an additional vulnerability to exploit.

Can I skip low priority items?

Low priority items provide defense-in-depth but aren't immediate risks. Address all critical and high items before launch. Low items can be added post-launch, but shouldn't be ignored entirely - they protect against edge cases and future vulnerabilities.

How often should I re-run this checklist?

Re-run after major feature additions, authentication changes, or new database tables. Set up automated scanning with VAS to catch regressions. Many teams integrate security scans into their CI/CD pipeline for continuous verification.

What does 'Auto-Scanned' mean on checklist items?

Items marked 'Auto-Scanned' can be automatically verified by VAS. Instead of manually checking each item, run a VAS scan to instantly verify these items against your deployed application. Non-automated items require manual verification.
