Why This Security Checklist Matters

Security checklists serve as systematic guides for identifying vulnerabilities that might otherwise be overlooked during rapid development cycles. For Neon 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 Neon 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

Row Level Security

critical

Enable RLS on all tables with user data

Auto

Neon supports full PostgreSQL RLS - use it for multi-tenant security

critical

Write RLS policies for each operation

Auto

Create SELECT, INSERT, UPDATE, DELETE policies

high

Pass user context for RLS

Use session variables to identify users in RLS policies

high

Test policies in Neon SQL Editor

Use Neon's SQL editor to verify RLS behavior

Connection Security

high

Use connection pooling securely

Neon's pooler handles connections - configure appropriately

high

Use SSL for all connections

Neon requires SSL by default - ensure your client supports it

critical

Protect connection strings

Auto

Store Neon connection strings in environment variables, not code

high

Use separate credentials per environment

Create different roles/databases for dev, staging, production

Branch Security

high

Use separate branches for environments

Neon branching creates isolated copies - use for staging

critical

Don't share production credentials with branches

Each branch has its own connection string

medium

Clean up unused branches

Delete old branches to reduce attack surface

high

Protect branch data in previews

Be aware that branch data may be from production snapshot

Access Control

medium

Review project member access

Audit who has access to your Neon project

high

Use roles with minimal privileges

Create database roles with only needed permissions

medium

Rotate credentials periodically

Regularly rotate database passwords and connection strings

medium

Enable IP restrictions if available

Restrict database access to specific IP ranges

Frequently Asked Questions

How does Neon branching affect security?

Each Neon branch has its own connection string. Use separate branches per environment (dev/staging/prod) with different credentials. Don't share production branch credentials with development environments.

Does Neon handle encryption automatically?

Neon encrypts data at rest and in transit. Connection strings use SSL by default. Your responsibility is protecting connection strings, implementing RLS, and using parameterized queries in application code.
