Practice Set 1

Relax. We'll talk through this in plain words — no textbook voice.

What you'll walk away with

  • Get comfortable with Practice Set 1, no need to be intimidated by it
  • Be able to run tools yourself inside an authorized lab environment
  • Be able to apply this concept immediately in a real assessment/report

Take a moment to think about this

This round is about putting the Basic/Intermediate concepts you've already learned into practice again — telling apart the CIA Triad and Passive vs Active Recon, being able to read Nmap output, and correctly applying legal/ethical boundaries are the skills you'll practice hands-on here. No task should take you more than 5 minutes.

Let's connect it to a real scenario

Task 1: Explain the difference between 'Confidentiality', 'Integrity', and 'Availability' in one sentence each. Task 2: Distinguish Passive Recon from Active Recon with 2 examples of each. Task 3: In an Nmap scan output, read and explain what it means when port 22 shows 'open' and port 3306 shows 'filtered' — what's the difference? Task 4: For the scenario 'a friend asked me to help check their WiFi router password, so I want to scan it', write out how you should approach it according to the legal/ethical framework (Basic lesson 2).

Let's walk through it together

# Task 4 - the friend/WiFi scenario
Even with a friend's verbal request, best practice is:
1. Get it in writing (even a simple text message confirming
   "yes, please test my home WiFi security")
2. Confirm scope: JUST the WiFi, not their laptop/phone/other
   devices, unless explicitly agreed
3. Stop immediately if anything unexpected happens
4. Report findings back to them directly, not publicly

Verbal permission is weaker than written, but for a home
WiFi favor with a friend it may be reasonable — for anything
involving a business, ALWAYS get written authorization first.
You should see
You'll come away able to explain the CIA Triad and Recon types, read Nmap output, and make a legal-scenario decision.

5-minute try-it

Write out your own personal policy for how you'd actually respond if you ran into the Task 4 scenario yourself (a request from a friend or family member).

A quick word of caution

Don't scan or test any real-world target for this round — the focus here is purely on practicing the concepts and decision-making logic.

Easy traps

  • Getting the CIA Triad muddled up as if 'they're all basically the same thing'
  • Assuming that a casual/verbal 'my friend's device' request is enough authorization on its own — it's important to clearly confirm the scope

Now try it yourself

Write out your own personal policy for how you'd actually respond if you ran into the Task 4 scenario yourself (a request from a friend or family member).

You'll know it worked when: You'll come away able to explain the CIA Triad and Recon types, read Nmap output, and make a legal-scenario decision.
