In the past, the word 'hacker' described a skilled computer expert who was good at understanding computer code and how computer systems work. But today, a 'hacker' spends a lot of time doing hacking activities and considers hacking as a way of life. Hacking means changing how a computer system works to do things the original creator didn't intend to do.
Before discussing how to become an ethical hacker, let's examine this role.

Understanding Ethical Hacking
Even though hacking often has a bad reputation, there are also good hackers known as "white hats" or ethical hackers. They play a very important role in the world of computer security. Instead of using their computer skills for bad things, they use them to find weaknesses in computer systems and data security. This helps protect businesses and organizations from people who want to harm hacking.
Now, let's examine what it means to be an ethical hacker.
Role of an Ethical Hacker
Specialized Cybersecurity Role
Ethical hacking represents a specialized niche within the broader field of cybersecurity. Unlike traditional cybersecurity, which often focuses on defending against cyber threats, ethical hacking involves actively testing and probing systems for weaknesses. Ethical hackers are security professionals who act as friendly "attackers" to identify vulnerabilities before malicious hackers can exploit them.
Diverse Work Settings
Ethical hackers have the flexibility to work in various environments. They can operate independently as freelance security consultants, offering their expertise to organizations on a project basis. Alternatively, they may work as part of a company's internal security team, collaborating closely with IT staff to strengthen the organization's defenses. Another option is to work as simulated offensive cybersecurity experts, where they simulate cyberattacks to evaluate an organization's preparedness and response.
Understanding Hacking Techniques
Ethical hackers must stay up-to-date with the latest hacking techniques and tools to be effective. This knowledge equips them with the skills to identify vulnerabilities that malicious hackers might exploit. Ethical hackers often learn continuously, participate in training programs, and stay informed about emerging cybersecurity threats.
Tailored Expertise
In-house ethical hackers may specialize in specific software applications, digital assets, or industry-specific systems. Their expertise is customized to address the unique security challenges faced by their organization. This specialization allows them to focus on critical areas, providing a more targeted and effective security approach.
Legal and Ethical Focus
Ethical hackers operate within the bounds of the law and adhere to strict ethical standards. They follow a code of conduct that prohibits any malicious or unauthorized activities. Instead, their activities are sanctioned and aimed at improving security. This ethical approach distinguishes them from black-hat hackers who engage in illegal and harmful activities.
Critical Cybersecurity Role
Ethical hackers play a critical role in enhancing an organization's cybersecurity posture. By actively seeking out vulnerabilities and weaknesses, they help organizations preemptively identify and address security risks. This proactive approach is essential in the ever-evolving landscape of cyber threats, allowing organizations to strengthen their defenses and protect sensitive data from potential breaches. Ethical hackers contribute to a more robust and resilient cybersecurity ecosystem.

Talk to an ExpertAppeal of an Ethical Hacking Career
A career in ethical hacking can be attractive for people who love computers and enjoy tackling challenges. It allows you to use your technical skills to break into computer systems, but you're doing it for a good reason. You get paid well, too. However, getting started in this field can be tough, but with hard work, you can build a successful legal career.
Now, let's explore the steps to become an ethical hacker.
10 Steps to Become an Ethical Hacker
Step 1: Get good at using LINUX/UNIX, an open-source operating system known for its strong security. Kali Linux is a popular version of LINUX customized for hacking.
Step 2: Become a pro at C programming, the foundation of all programming languages. Learning other languages like Python, JavaScript, PHP, and SQL will improve you.
Step 3: Learn how to stay anonymous online. This is important for ethical hackers. Tools like Anonsurf, Proxychains, and MacChanger can help you hide your identity.
Step 4: Understand networking concepts like TCP/IP, subnetting, and protocols. Tools like Nmap and Wireshark can be very useful.
Step 5: Explore the dark web, a hidden part of the internet that regular search engines can't find. You'll need special tools like Tor to access it. The dark web has legal and illegal stuff, and it's important to understand how it works.
Step 6: Learn about cryptography, which is all about secret codes and writing. It's really useful for hacking. You'll need to know how to encrypt (lock) and decrypt (unlock) information.
Step 7: Dig deeper into hacking by studying things like SQL injections (a way to hack into databases), penetration testing (pretending to be a hacker to find weaknesses), and vulnerability assessment (looking for security holes). Stay updated on the latest security trends and tools.
Step 8: Focus on finding vulnerabilities in computer systems and networks. There are tools like Nessus, OpenVAS, Nikto, Nmap, and Wapiti that can help with this.
Step 9: Practice your hacking skills in different scenarios, from simulations to real-world challenges like bug bounty programs, where you get paid for finding security issues.
Step 10: Connect with other hackers in online communities, forums, and discussions. Collaboration and knowledge-sharing are key in this field.
These steps can help you build a solid foundation for a career in ethical hacking.
