To this day, a job as an ethical hacker is not only feasible but also entirely desirable. It is not necessary to have prior understanding of programming languages such as C, C++, or Python in order to become an ethical hacker; we will walk you through the basic stages to become an ethical hacker in this complete book.
What is Ethical Hacking?
It is essential to have a fundamental understanding of what ethical hacking is and why it is so vital in the field of cybersecurity before delving into the specific processes that are required to become an ethical hacker. Hackers that adhere to ethical standards are experts who are employed by businesses to examine their computer systems, networks, and applications for vulnerabilities. For the purpose of assisting the company in strengthening its security measures, the objective is to identify vulnerabilities that could be exploited by hackers.
The practice of ethical hacking is frequently carried out in accordance with a legally binding contract and with the organization’s express authorization. In contrast to hackers who use black hats, ethical hackers adhere to a stringent code of conduct and work toward enhancing security rather than causing it harm. With the intention of safeguarding systems and protecting sensitive data, ethical hackers employ the same tools, strategies, and approaches as malevolent hackers. However, their goal is to protect sensitive data.
Step 1: Understand Networking and Operating Systems
One of the most important skills for any ethical hacker is understanding how networks and operating systems function. Without a basic knowledge of these concepts, you’ll struggle to grasp the nuances of penetration testing. Fortunately, you don’t need to be a programming expert to build a strong foundation in networking and operating systems.
Networking Concepts
Hackers that adhere to ethical standards are required to have a strong understanding of the fundamentals of networking, including TCP/IP, DNS, HTTP/HTTPS, IP addresses, subnets, and network protocols. It is possible to uncover potential vulnerabilities and exploitation points on a network if you are aware of the manner in which data is transported between devices on the network. In addition to this, you should be familiar with the operation of firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), and virtual private networks (VPNs).
You will be able to execute activities such as port scanning (using tools such as Nmap), network sniffing (using Wireshark), and vulnerability scanning if you have a solid understanding of networking.
Operating Systems (OS)
In the course of their job, ethical hackers are familiar with a variety of operating systems, including Linux and Windows. Linux is the favored choice for many penetration testing activities due to its versatility and the availability of powerful open-source tools such as Kali Linux. Windows continues to be the dominant operating system in the majority of enterprise contexts.
Linux is equipped with its own set of commands and tools, which are regularly utilized by ethical hackers. Even if you are not an expert in programming, it is imperative that you acquire the knowledge necessary to navigate a Linux environment by utilizing the terminal. In addition, you should familiarize yourself with the fundamental Linux tools that are used for penetration testing, such as Metasploit, nmap, and netcat.
You are need to have knowledge of how to operate with PowerShell and the command prompt in order to do Windows. Both operating systems have their own unique characteristics and vulnerabilities, and it is essential for penetration testers to be able to traverse and exploit these differences for maximum effectiveness.
Step 2: Learn Cybersecurity Basics
Once you have a foundational understanding of networking and operating systems, the next step is to dive deeper into cybersecurity principles. This involves learning about common threats, attack vectors, and security measures. Understanding the basics of cybersecurity will help you think like an attacker, which is crucial for penetration testing.
Types of Cybersecurity Threats
Familiarize yourself with the different types of cybersecurity threats such as phishing, malware, ransomware, denial of service (DoS) attacks, and SQL injection. These are common tactics that attackers use to breach systems. Ethical hackers must understand these threats and how to prevent them.
Vulnerabilities and Exploits
You’ll also need to understand the various vulnerabilities that hackers exploit to gain unauthorized access to systems. This includes understanding buffer overflows, privilege escalation, cross-site scripting (XSS), cross-site request forgery (CSRF), and SQL injection. Ethical hackers frequently encounter these vulnerabilities during penetration testing engagements, and knowing how to spot and exploit them is essential to securing systems.
Security Protocols
Learn about security protocols like SSL/TLS (for secure communication), SSH (for secure remote access), and WPA2 (for Wi-Fi security). As an ethical hacker, you’ll often need to analyze traffic encrypted by these protocols and determine if they have been implemented securely.
Step 3: Practice with Penetration Testing Tools
When it comes to ethical hacking, one of the most fascinating elements is the utilization of penetration testing tools to locate and attack vulnerabilities. When it comes to building bespoke scripts or tools, having coding abilities is beneficial; nevertheless, the majority of penetration testers may get started without having a significant amount of programming experience by using pre-built tools.
Within the Kali Linux distribution, you will have access to a number of the penetration testing tools that are utilized the most frequently. An extensive collection of security tools, such as network scanners, vulnerability scanners, and exploit frameworks, are already pre-installed on Kali during the installation process.
Nmap and Netcat
Nmap is one of the most widely used tools for network discovery and security auditing. Ethical hackers use Nmap to scan networks and identify open ports, services running on those ports, and potential vulnerabilities. Similarly, Netcat is a powerful tool for reading and writing data across network connections and is often used in penetration testing for creating reverse shells or transferring data.
Metasploit
Metasploit is an advanced penetration testing framework that allows ethical hackers to find, exploit, and validate vulnerabilities in systems. It includes a vast collection of exploits, payloads, and auxiliary modules that automate many penetration testing tasks. Even without programming skills, Metasploit’s easy-to-use interface can help you quickly exploit vulnerabilities and demonstrate the effectiveness of a security flaw.
Wireshark
Wireshark is a network protocol analyzer that allows you to capture and analyze network traffic. Ethical hackers use Wireshark to perform packet analysis and discover sensitive data being transmitted over the network. Learning to use Wireshark is essential for identifying security issues like unencrypted data transmissions.
Burp Suite
Burp Suite is an integrated platform for performing security testing of web applications. It includes tools for intercepting traffic between your browser and a web server, analyzing vulnerabilities in web apps, and automating attacks like SQL injection or cross-site scripting (XSS). Burp Suite is a must-learn tool for penetration testers focusing on web security.
Step 4: Build a Home Lab
One of the most effective ways to learn ethical hacking is by building a home lab where you can practice your skills in a safe and controlled environment. A home lab allows you to experiment with penetration testing tools and techniques without risking harm to any real systems.
You can set up your home lab using virtual machines (VMs) or cloud-based services. Using software like VirtualBox or VMware, you can create virtual machines that run various operating systems like Kali Linux, Windows, and vulnerable targets like Metasploitable. By simulating real-world environments, you can practice identifying and exploiting vulnerabilities in different OSes and software.
If you don’t have the hardware for a local lab, consider using cloud-based platforms like AWS, Google Cloud, or Azure to create virtual machines for penetration testing. Many cloud providers offer free or low-cost credits to get started.
Additionally, platforms like Hack The Box and TryHackMe provide gamified, interactive learning environments where you can practice penetration testing techniques on intentionally vulnerable machines.
