Asking ten potential ethical hackers about the first steps they should take will reveal that most of them would suggest starting with using certain tools such as Burp Suite, Metasploit, or Nmap. However, those tools are only useful when you understand the systems they are designed to assess. Without understanding how networking, Linux, or web application technologies work, using any security tools will be nothing more than pushing buttons and analyzing results.
That’s why ethical hacking is best learned in phases rather than by jumping straight into tools.
Normally, security specialists begin by learning networking, operating systems, and scripting, then proceed to reconnaissance, vulnerability testing, exploiting, and finally to security testing itself. This ethical hacking roadmap follows the same progression.
What Is Ethical Hacking (and What It Is Not)?
Ethical hacking, at the core, involves identifying the vulnerabilities present in the system/application/network with the permission of the owner of the system. It is the process of finding out vulnerabilities before the malicious actors make use of them. Hence, it forms an integral part of the cybersecurity strategy.
However, there is a fine line between ethical hacking and other activities that need permission from the system owner. Using the same tools and techniques in unauthorized penetration testing makes the act unethical. This means that it depends upon the permission, scope, and purpose of the action rather than the tool or the technique being used.
Before the process of testing starts, there must be a set of clear rules of engagement that define the scope of the testing, actions that can and cannot be done in testing. Responsible disclosure, legalities, and scope formation are the principles of ethical hacking that you should keep in mind during the course.

Phase 1: Foundations Networking & Operating Systems
Many aspiring ethical hackers want to start with tools and exploits, but security testing becomes much easier when you understand how systems communicate and operate. That’s why networking for ethical hacking is often the first skill experienced professionals recommend learning.
At this stage, focus on understanding:
- TCP/IP and the OSI Model
- IP Addressing and Subnetting
- Common Protocols (HTTP, HTTPS, DNS, DHCP, FTP, SSH)
- Ports and Services
- Basic Network Troubleshooting
- Windows Fundamentals
- Linux Fundamentals
- File Systems, Processes, and User Permissions
It is not about remembering all protocols and commands. Rather, it is about knowing answers to such questions as: how does a browser connect to a website? What happens when there is a DNS query? What is the service running on that particular port? Such questions lay down the basics of scanning, enumeration, exploitation, and many other hacking operations.
These foundational concepts are among the most important ethical hacker skills you’ll build throughout your cybersecurity journey.
Phase 2: Linux & Scripting (Kali, Bash, Python)
Most security tools run on Linux, which is why learning Linux early can make the rest of your journey significantly easier. For Kali Linux for beginners, your focus should be on working smoothly with the command line, file systems, permissions, and basic system administration tasks.
Key skills to learn in this phase include:
- Linux Command Line Basics
- File and Directory Management
- User and Permission Management
- Package Installation and Updates
- Bash Scripting Fundamentals
- Python Basics
- File Handling and Automation
- Working with APIs and Logs
Most newcomers spend many hours browsing through tools that can perform actions that would take just a few lines of script in Bash or Python. The learning of the basics of scripting early on is worthwhile since you are going to need it all along your way in cybersecurity, regardless of whether you analyze logs, parse data obtained during a scan, or develop some automation processes.
Before moving on, be sure to have enough practice working from the command line without relying on a graphical interface.

Phase 3: Reconnaissance & Scanning Tools
Before assessing a system for vulnerabilities, you first need to understand the systems, services, and technologies that are present. Reconnaissance is the process by which information is collected about a target, and scanning enables one to find out all active hosts and ports, services running on those systems, and possibly other vulnerabilities. The reconnaissance and scanning phase is crucial for any professional penetration test.
Key concepts and tools to learn include:
- Footprinting and Information Gathering
- DNS Enumeration
- Network Discovery
- Port Scanning
- Service Enumeration
- Operating System Fingerprinting
- Vulnerability Scanning Basics
- Nmap Scanning
- Whois and DNS Lookup Tools
It’s important to remember that scanning systems without permission can be both unethical and illegal. Always practice in authorized environments such as home labs, training platforms, or systems that explicitly allow security testing. The goal of this phase is to learn how to map and understand a target environment before attempting any form of security assessment.
You can explore Nmap and network scanning concepts in more detail: Modern Software & AI Engineering Course.
Phase 4: Exploitation Web & Network Attacks
Once you understand how to discover systems and services, the next step is learning how vulnerabilities are identified and validated during a security assessment. This phase introduces some of the most common issues encountered in web applications and networks, along with the penetration testing tools used by security professionals to assess them.
Key topics to learn include:
- OWASP Top 10 Security Risks
- SQL Injection (SQLi)
- Cross-Site Scripting (XSS)
- Authentication and Session Management Issues
- Security Misconfigurations
- Basic Network Exploitation Concepts
- Vulnerability Validation and Reporting
- Burp Suite
- Metasploit Framework
Our aim is not to hack into any random system but to learn about vulnerabilities, how to detect them, and how to remediate them. You should always try in your laboratory environment, an application purposely vulnerable to testing, or places where you are explicitly authorized for security testing.
While advancing in the field, you need to work on creating methodologies and not just on tools. Security professionals use various tools like Burp Suite and Metasploit, but the knowledge of the vulnerability itself is much more valuable than just learning the tools themselves.

Phase 5: Practice Labs, CTFs & Bug Bounties
At some point, reading about vulnerabilities is no longer enough. You need hands-on practice. Hacking is an applied science, and only by applying yourself and getting hands-on practice will you be able to learn how to use networking, Linux, reconnaissance, and exploitation together.
Some of the best ways to practice legally include:
- Guided Cybersecurity Labs
- Capture The Flag (CTF) Challenges
- Vulnerable Applications and Virtual Machines
- Home Lab Environments
- Bug Bounty Programs with Clearly Defined Scope
For beginners, CTFs provide a structured way to practice networking, Linux, web security, and cryptography concepts. The aim is not to solve the toughest problems right away, but rather to create a certain method for problem-solving and research.
In terms of practice, a useful approach would be to allocate some time weekly to study some concepts, work out problems, keep notes, and go through walk-throughs where needed. Practical work is usually much more beneficial than tool learning.
