Essential Foundations for Learning Ethical Hacking​

Computer & Internet Fundamentals​

Start with the basics. To become a good ethical hacker, you must understand how computers and the internet actually work. Learn:

• What CPU, RAM, storage mean
• What an IP address is
• The difference between LAN and WAN
• How data moves across networks

These concepts build the foundation for everything you’ll learn later.

Networking Essentials​

Networking is the backbone of cybersecurity. You should fully understand:

• TCP/IP model
• DNS, DHCP
• Routing and switching
• Network devices (Switch, Router, Firewall)
• OSI Model

A simple example using Python to test connectivity:

import os

host = "google.com"
response = os.system(f"ping -c 4 {host}")

if response == 0:
    print("Network is up!")
else:
    print("Network is down!")

Linux & Command Line Basics​

Almost every security tool runs on Linux, especially Kali Linux.
You need to learn core command-line skills like:

ls
cd
ifconfig
chmod
ping
cat /etc/passwd

Linux is the main playground for ethical hackers, so mastering it is crucial.

Basic Programming​

You don’t have to be a software engineer, but basic programming is very important. It helps you automate tasks, write scripts, and understand vulnerabilities.

Useful languages to start with:

• Python (most recommended)
• Bash
• JavaScript (for web testing)

Example Python script for collecting subdomains:

import requests

domain = "example.com"
url = f"https://crt.sh/?q={domain}&output=json"
data = requests.get(url).json()

for entry in data:
    print(entry["name_value"])

Operating System Internals​

You must understand how operating systems work inside:

• How files are stored
• How memory is managed
• What processes and threads are
• How the kernel interacts with hardware

This helps you discover deeper vulnerabilities.

Web Technologies & the HTTP Protocol​

Almost every penetration tester deals with web applications. Learn:

• HTML, CSS, JavaScript basics
• How cookies and sessions work
• HTTP methods like GET, POST, PUT, DELETE
• How web servers and APIs function

Example reading HTTP headers:

import requests

response = requests.get("https://google.com")
print(response.headers)

Creating Your Lab Environment​

Never practice hacking on real systems. Set up a safe environment using:

• VMware
• VirtualBox
• Kali Linux
• Metasploitable2
• VulnHub vulnerable machines

This lets you practice legally and safely.

Introduction to Ethical Cybersecurity​

Learn the difference between:

• White Hat hackers
• Black Hat hackers
• Gray Hat hackers

You should also understand cyber laws, ethics, and responsible disclosure.

Intermediate Skills Every Ethical Hacker Needs​

Information Gathering​

This is the first step during penetration testing. Learn how to collect info about your target.
Useful tools:

• Nmap
• theHarvester
• Shodan
• Whois

Network Scanning​

Scan networks to identify devices, IPs, and open ports.
Example Nmap command:

nmap -sV -A 192.168.1.1/24

Enumeration Techniques​

Enumeration helps you dig deeper into services, users, and configurations.
Example of SMB enumeration:

enum4linux -a 192.168.1.10

Vulnerability Assessment Tools​

Learn how to use tools that scan for weaknesses, such as:

• Nessus
• OpenVAS
• Nikto

These tools help you detect misconfigurations, outdated software, and security flaws.

Service Disruption Testing​

Understand how systems react under stress or during DoS-style attacks. This helps check resiliency.

Malware Concepts & Prevention​

You should know:

• Types of malware (worms, Trojans, ransomware)
• How malware spreads
• How to detect and prevent it

Network Monitoring & Packet Analysis​

Master tools like:

• Wireshark
• Tcpdump

You'll learn how to capture and analyze packets to understand network behavior and spot suspicious activity.

Social Engineering Awareness​

Many hacks happen because of human mistakes. Learn about:

• Phishing
• Pretexting
• Baiting
• How to defend against them

Session Security & Spoofing​

Understand how attackers hijack sessions and spoof IPs. Learn how to secure sessions, cookies, and user authentication.

Advanced Skills for Serious Ethical Hackers​

Web Application Penetration Testing​

Web testing is one of the biggest parts of ethical hacking. Learn to find vulnerabilities like:

• SQL Injection
• XSS
• CSRF
• LFI/RFI

Example simple SQL injection payload:

' OR 1=1 --

Wireless Network Security​

Learn to secure and attack WiFi networks. Tools include:

• Aircrack-ng
• Wifite

Intrusion Detection Systems (IDS)​

Study systems like:

• Snort
• Suricata

These help detect suspicious traffic and possible attacks.

Cryptography Essentials​

Learn the basics of encryption technologies:

• Hashing
• Symmetric encryption
• Asymmetric encryption
• Public/private keys
• SSL/TLS

This helps you understand how data stays secure.

Exploitation Tools​

Tools you must know:

• Metasploit Framework
• SQLMap
• Burp Suite

These help automate and execute vulnerability exploits.

Reverse Engineering Basics​
