## What it is
A security knowledge framework maintained by the ffffffff0x team, organized as a large collection of Markdown notes covering web security, ICS/industrial control security, forensics, incident response, blue team infrastructure, post-exploitation, Linux security, and CTF/vulnerable-machine writeups. It serves as a structured learning resource with roadmaps for beginners building infosec knowledge.

## Use cases
- learn penetration testing from a structured roadmap
- study blue team forensics and incident response techniques
- find CTF tools and writeups for vulnerable machines like VulnHub and HTB
- learn industrial control system (ICS) and PLC attack knowledge
- look up security hardening and monitoring resources
- prepare for red team vs blue team operations

## When to choose
- you want a free, comprehensive Chinese-language infosec knowledge base spanning red team and blue team topics
- you are a beginner needing a learning roadmap for security
- you need curated writeups and tool lists for CTFs and lab machines

## When to avoid
- you need actively maintained tooling or executable software rather than reference notes
- you require a license permitting commercial use (it is CC BY-NC-SA with no OSS license file)
- you need English-only documentation

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, security, developer-tools
- domain: security, penetration-testing, tutorials, awesome-lists
- platform: windows, cross-platform
- tags: security-knowledge-base, pentest, redteam, blueteam, ctf, ics-security, forensics, incident-response, writeups, wiki, linux
