Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 2812, "days_push": 8, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
The OWASP Cheat Sheet Series is a curated collection of concise, high-value reference documents covering application security best practices. It is maintained as a Markdown repository that builds into an official OWASP website with offline download options.

## Use cases
- learn secure coding practices for web applications
- find guidance on preventing SQL injection and XSS
- reference authentication and session management best practices
- review application security checklists before a code review
- train developers on OWASP security topics
- download an offline security reference for the team

## When to choose
- you need authoritative, community-reviewed application security guidance
- you want concise best-practice references rather than lengthy standards
- you need an offline or self-hosted copy of security documentation

## When to avoid
- you need a runnable security tool or scanner rather than documentation
- you need vendor-specific or compliance-mapped security controls
- you need interactive tutorials or hands-on labs

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, security
- domain: security, web-development, developer-tools, documentation
- platform: python, cross-platform
- tags: owasp, cheatsheets, appsec, best-practices, application-security, security-guidance, web-server
