A Simple Guide for Students & Teachers

Understanding Knowledge

Knowledge is like cooking. Data is the ingredients, Information is the recipe, and Wisdom is knowing when to bake the cake.

The DIKW Pyramid

The hierarchy of value: moving from raw signals to applied judgment.

Wisdom

Applied judgment. Knowing "when" and "why" to use knowledge.

Knowledge

Understanding & Context. The "how it works" mechanics.

Information

Data with meaning. "What it means."

Data

Raw facts and numbers. The building blocks.

10 Types of Knowledge

Different ways we store, access, and prove what we know, with examples from Tech & Security.

Explicit

Codified, written down. Documents and databases.

  • Security Policies
  • Linux Man Pages

Tacit

Experience-based. Intuition and mindset.

  • Threat Hunting
  • Debugging Sense

Procedural

Step-by-step "how to". Scripts and processes.

  • Incident Response
  • Bash Scripts

Declarative

Facts and definitions. "Knowing that".

  • OSI Model
  • SSH is Port 22

Empirical

Gained through observation and data analysis.

  • Log Analysis
  • Pen-testing

Theoretical

Abstract principles. The "why" behind the tech.

  • Encryption Math
  • Big O Notation

Practical

Hands-on skill. Physical application.

  • Crimping Cables
  • Racking Servers

A Priori

Independent of experience. Logic and reason.

  • Boolean Logic
  • Subnetting Logic

A Posteriori

Derived from experience. "I know because I checked."

  • "Server is down"
  • Forensics

Linguistic

Understanding syntax, symbols, and languages.

  • Code Syntax
  • Regex Patterns
Bloom's Taxonomy

The Learning Ladder

Ascending from basic commands to automation mastery.

6. CREATE

Build a tool. Create a full system monitoring suite.

5. EVALUATE

Code Review. Is this script secure? Is `rm -rf` dangerous?

4. ANALYZE

Debugging. Why did the cron job fail? Log parsing.

3. APPLY

Scripting. Writing a bash script to backup files.

2. UNDERSTAND

Syntax & Logic. How pipes (`|`) and loops work.

1. REMEMBER

Commands. Memorizing `ls`, `grep`, `chmod`.

Knowledge Management Cycle

1. CAPTURE

Document it

2. STORE

Organize it

3. SHARE

Teach it

4. UPDATE

Keep it fresh

5. PROTECT

Secure it

What is a Knowledge Gap?

It is the difference between what you know and what you need to know to solve a problem.

Everyday Example:

You want to cook Thai food but only know how to make sandwiches. The gap is the spices and techniques you haven't learned.

Cybersecurity Example:

Attackers exploit gaps like zero-day vulnerabilities. Defenders must continuously learn to close them.
