WorldSkills Cyber Security CoBOK

Welcome to the Competition Body of Knowledge for WorldSkills Cyber Security.

This is the single source of truth for competitors, experts and trainers preparing for WorldSkills Cyber Security, from the WorldSkills UK national competition to the WorldSkills International finals. It is organised around the four areas the competition covers:

• Infrastructure hardening and secure coding
• Digital forensics and incident response
• Offensive operations (red team CTF)
• Defensive operations (blue team)

Every page maps to the WorldSkills Occupational Standards (WSOS) 2026, the standard each competition is marked against.

About This Site

Caution

CoBOK is an unofficial study guide. WorldSkills International and WorldSkills UK don’t endorse it.

• Example areas, not the test. Each competition’s tasks are written for that competition and kept confidential. The topics here are areas worth preparing in, drawn from public standards and competition experience, not a description of what any test project contains.
• Closed book. Competitions run without internet access or reference material, so practise working from what you know, offline.
• Subject to change. Modules, formats and marking change between competitions and between years. Check the current brief, technical handbook and rules for your competition, and treat these pages as preparation around them.

🎯 Two Ways to Navigate

This site supports two different navigation perspectives without duplicating content:

1. 📍 Stage-Centric View (Recommended for learners)

Start here if you’re preparing for a specific competition level.

The Competition Roadmaps are learning paths tailored to each stage:

• 🇬🇧 The UK pathway - The five UK stages, from pre-qualifier to Team UK, and which roadmap covers each
• 🥉 Regional - Entry-level baseline competencies
• 🥈 National - Intermediate skills with less guidance
• 🥇 Squad/Team Selection - Advanced techniques and edge cases
• 🏆 International Finals - Peak performance preparation

Each roadmap links directly to the specific sections of technical content you need at that stage (using anchor links). This prevents you from getting overwhelmed by content that’s beyond your current level.

2. 📚 Topic-Centric View (Body of Knowledge)

Use this for deep-diving into specific technical domains.

The Body of Knowledge contains all canonical technical content, organised by competition area:

• 🔨 Infrastructure Hardening
• 🔍 Digital Forensics
• ⚔️ Offensive Operations
• 🛡️ Defensive Operations

Every technical concept exists exactly once in these sections. Roadmaps link to these pages using stable anchor links.

🧭 Design Philosophy

Competition-Focused, Not Academic

This CoBOK teaches what a WorldSkills competitor actually needs, nothing more. Every page maps directly to:

• A realistic competition task
• A marking scheme requirement
• A strategy or workflow
• Wrong paths / false flags to avoid
• Skill level requirements (Regional → National → International)

Work in Progress

This CoBOK is under active development. Content structure is complete, but individual pages are being populated based on official test projects and competition experience.

Single Source of Truth

No content duplication. If something appears in multiple places, it’s via anchor links, not copied prose. This ensures accuracy and makes updates manageable.

🚀 Getting Started

New to WorldSkills Cyber Security?

1. Read the Regional Roadmap to understand baseline expectations
2. Focus on HIGH priority topics first
3. Use the Body of Knowledge for deep technical learning
4. Practice with cheat sheets for speed and muscle memory

Preparing for nationals or higher?

1. Review your stage-specific roadmap (National / Squad / International)
2. Deep-dive into the technical content from the Body of Knowledge
3. Practice under time pressure using past test projects
4. Focus on documentation quality (screenshots, writeups, evidence)
