## What it is
A practical open-source security guide and checklist for web developers covering authentication, authorization, encryption, sessions, headers, configuration, and common attacks. It is written as a book-style repository of markdown documents aimed at both beginners and experienced developers.

## Use cases
- learn web application security fundamentals
- find a security checklist before launching a web app
- understand how to store passwords securely
- learn the difference between encoding, encryption, and hashing
- review common web vulnerabilities like XSS, CSRF, and SSRF
- checklist for securing API endpoints and OAuth flows

## When to choose
- you are a web developer wanting practical, actionable security guidance
- you need a pre-launch security checklist for a web application
- you are teaching or onboarding developers on secure coding practices

## When to avoid
- you need a comprehensive, formal security standard or compliance reference
- you need tooling or automated security scanning rather than documentation
- you need deep, up-to-date coverage of a specific niche vulnerability

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: security, documentation
- domain: security, web-development, developer-tools, tutorials
- platform: cross-platform
- tags: security-checklist, web-security, authentication, authorization, encryption, security-guide, book, web-server
