Security Baseline

Establish the security floor for any production website or web app. Stack-agnostic. Covers the things that should be in place before public launch and verified periodically after.

When to use

Pre-launch security review
Setting up a new site or environment
Periodic security audit (quarterly recommended)
Onboarding a new vendor or third-party integration
Responding to a security finding or report
Hardening after an incident

When NOT to use

Active incident response (use incident-response)
Code-level security review (use code-review-web)
Email-specific authentication (SPF/DKIM/DMARC) (use email-deliverability)
DNS-level security (CAA, DNSSEC) (use domain-strategy)
Performance-related security (DDoS protection sizing) (use performance-optimization)

Required inputs

The site or app in scope (URLs, environments)
The hosting platform and CDN
Authentication method (if any)
Third-party scripts and integrations
Compliance context (PCI, SOC2, GDPR, etc., if applicable)
Existing security tooling

The framework: 6 layers

Security is layered. Each layer addresses a different attack surface.
