Skills You Should Learn Before Using Kali Linux

Before you start using Kali Linux tools, build a strong foundation. These basics will make your learning smoother and safer.

1. Basic Linux Commands

You should know how to move between folders, create files, edit text, install packages, check processes, and understand file permissions.

Commands like ls, cd, pwd, mkdir, cat, nano, and sudo apt update are basic but important.

2. Networking Fundamentals

Networking is the backbone of ethical hacking. Learn IP addresses, ports, protocols, DNS, HTTP, HTTPS, TCP, UDP, routing, and firewalls.

For example, if you do not understand what port 80 or port 443 means, tools like Nmap or Burp Suite will feel confusing.

3. Web Application Basics

Many ethical hacking learners start with web security. Learn how websites work, how login pages function, what cookies are, how APIs work, and how databases connect with applications.

4. Cybersecurity Fundamentals

Understand common terms like vulnerability, exploit, payload, risk, threat, attack surface, authentication, authorization, encryption, and patching.

5. Legal and Ethical Hacking Rules

Ethical hacking is legal only when you have permission. Never scan, test, attack, or attempt to access any real system without written approval.

How to Set Up Kali Linux Safely
