Ethical hacking has become one of the most in-demand skills in the digital era. Whether you're a student, aspiring cybersecurity professional, or just curious about hacking, getting started doesn't have to be overwhelming. This 7-day ethical hacking roadmap for beginners is designed to help you grasp the basics, understand the tools, and get hands-on experience — all in just one week.

What Is Ethical Hacking? A Simple Explanation for Beginners

Ethical hacking, also known as white-hat hacking, involves legally breaking into computers and systems to test and improve their security. Unlike malicious hackers, ethical hackers use their skills to protect organizations and prevent cyber attacks.

Ethical hackers often work in roles such as:

• Penetration tester

• Security analyst

• Vulnerability assessor

• Red team member

Their main goal? To identify weaknesses before real hackers do.

Who Can Learn Ethical Hacking?

Anyone with basic computer knowledge and curiosity about cybersecurity can start learning ethical hacking. It’s ideal for:

• Students and IT graduates

• Network administrators

• Programmers and developers

• Tech enthusiasts interested in security

No prior hacking experience is required. However, having a fundamental understanding of networking and operating systems will accelerate your learning.

Day 1: Understand the Basics of Ethical Hacking

Start with the foundational knowledge. On Day 1, focus on:

• What is hacking and who are hackers (white-hat, black-hat, gray-hat)?

• Legal aspects and ethics in cybersecurity

• Understanding cybersecurity terminologies

• Familiarize yourself with the Hacker Mindset

• Intro to CEH (Certified Ethical Hacker) and OSCP paths

Tools/Resources:

• Read blogs and beginner’s guides

• Watch YouTube videos on “What is Ethical Hacking?”

• Join beginner forums or subreddits

Day 2: Learn About Operating Systems (Linux is Key)

Linux is the go-to OS for ethical hackers. On Day 2:

• Install Kali Linux or use a virtual machine like VirtualBox

• Learn basic Linux terminal commands (ls, cd, mkdir, chmod, etc.)

• Understand file structures, permissions, and users

• Explore the Linux directory hierarchy: /etc, /bin, /var, etc.

Tools/Resources:

• TryHackMe’s Linux Basics room

• Online Linux command cheat sheets

• YouTube: “Linux for Ethical Hackers”

Day 3: Dive into Networking Fundamentals

A good ethical hacker understands how networks work. Day 3 should focus on:

• What is a network? LAN, WAN, IP, Subnet, MAC

• How data moves (TCP/IP, packets, ports)

• What is DNS, DHCP, VPN, and NAT?

• OSI vs TCP/IP models

• Common ports: FTP (21), SSH (22), HTTP (80), HTTPS (443)

Hands-On Tip: Use tools like Wireshark to inspect network traffic.

Day 4: Explore Footprinting and Reconnaissance

Before attacking, hackers gather information about their targets. On Day 4:

• Passive vs Active Reconnaissance

• Google hacking (dorking)

• WHOIS lookup and DNS enumeration

• Scanning websites for open ports and subdomains

Tools to Learn:

• Nmap – for network scanning

• theHarvester – for email/host info gathering

• Shodan – for IoT device footprinting

• Recon-ng – for automation of reconnaissance

Day 5: Learn Scanning and Vulnerability Detection

After reconnaissance, ethical hackers scan the system for weaknesses.

• Types of scans: TCP, SYN, UDP

• Identify open ports and services

• Banner grabbing and OS detection

• Understand CVEs (Common Vulnerabilities & Exposures)

• Basics of vulnerability scanning

Tools to Practice:

• Nmap and Zenmap

• Nikto – for website vulnerability scanning

• OpenVAS – automated vulnerability scanner

• SearchSploit – find local exploits based on CVE

Day 6: Introduction to Exploitation and Gaining Access

Now comes the exciting part — exploitation.

• Understand buffer overflows, SQL injection, and remote code execution (RCE)

• Explore Metasploit Framework basics

• Learn how exploits work in real-world cases

• Try simple exploits on intentionally vulnerable machines

Practice Labs:

• Metasploitable 2

• DVWA (Damn Vulnerable Web Application)

• TryHackMe: Basic Pentesting Room

• Hack The Box (beginner-friendly machines)

Day 7: Practice Privilege Escalation and Reporting

After initial access, hackers try to escalate privileges to gain more control.

• Windows and Linux privilege escalation basics

• Common misconfigurations: weak permissions, SUID, kernel exploits

• Post-exploitation tasks: creating persistence, covering tracks

• Learn the importance of ethical reporting

End With:

• Document everything

• Write a sample penetration test report

• Reflect on what you've learned

Tools for Day 7:

• LinPEAS & WinPEAS

• PowerUp & SharpUp

• GTFOBins

The world needs more ethical hackers to defend against rising cyber threats — and your journey starts now.

 FAQs

What is ethical hacking and how is it different from malicious hacking?

Ethical hacking involves testing systems for vulnerabilities to improve security, while malicious hacking aims to exploit weaknesses for personal gain or damage.

Can I learn ethical hacking without a technical background?

Yes, many ethical hacking courses are beginner-friendly and start with fundamentals, making it accessible even if you’re not from an IT background.

Is ethical hacking legal in 2025?

Yes, ethical hacking is legal when performed with permission and within the boundaries of cybersecurity laws.

What should I learn first in ethical hacking?

Start with networking, operating systems (especially Linux), and basic cybersecurity concepts before moving into tools and practical labs.

Which OS is best for learning ethical hacking?

Kali Linux is the most popular OS among ethical hackers due to its pre-installed security tools and penetration testing features.

How long does it take to become an ethical hacker?
