Penetration testing is an invaluable skill in the world of cybersecurity. It involves attempting to access systems and networks without authorization to uncover potential vulnerabilities or weaknesses.

Being able to assess these risks, and respond with appropriate countermeasures appropriately, is essential for all organizations and their digital assets.

If you're looking for a basic step-by-step guide to becoming an expert penetration tester, this article will provide you with the needed knowledge.

What is Pen Testing?


Penetration testing, also known as pen testing or ethical hacking, is a cybersecurity practice that involves simulating cyberattacks to identify vulnerabilities in networks, systems, and applications.

Pen testers use manual and automated techniques to attempt to gain unauthorized access to systems to uncover potential weaknesses before malicious hackers exploit them.

What Is Penetration Testing/Pentest? Benefits & Its Types


By assessing how secure an organization's digital infrastructure is against real-world attacks, pen testers can help organizations reduce their exposure to data breaches and other cyber threats.

Pen testing exercises typically include finding system vulnerabilities, exploiting those vulnerabilities, attempting privilege escalation on user accounts, and breaching networks from external sources.

After performing these tests, pen testers will analyze the results for security flaws or weaknesses that attackers could use for malicious purposes.

Organizations can then address these issues before outside actors exploit them.

Obtain Qualifications


As a penetration tester requires dedication, time, and a commitment to learning. Individuals need to acquire specific certifications relevant to the field of study to demonstrate their knowledge about cyber security best practices and ethical hacking principles.

Obtaining the proper certifications can be daunting for those who are just starting, as there are several options to choose from.

But with some research and guidance, aspiring penetration testers can easily find their way to the best certifications that will help them achieve their goals in the field of cybersecurity.

Penetration Tester Certifications - Cyber Degrees


One of the most important requirements for becoming a penetration tester is obtaining an academic degree in Information Security or Computer Science.

This degree can be obtained through an online program or traditional university coursework. Additionally, some employers may require certification from organizations such as:


These certifications help demonstrate to potential employers that applicants have acquired industry-standard skillsets associated with penetration testing.

Also, Certifications provided by organizations such as Offensive Security Certified Professionals (OSCP) are some of the most popular choices among penetration testers.

These two provide foundational knowledge on hacking techniques and tools which make them perfect for new professionals entering this field.

They cover everything from scanning to exploitation techniques, cryptography, reverse engineering, and malware analysis – all skills required of the successful penetration tester.

Final Thought


Becoming a penetration tester is not an easy task. It requires a strong understanding of technology, security, and coding.

It also requires analytical skills and the ability to think outside the box. However, with dedication, hard work, and a passion for cybersecurity, penetration testers can become successful in this field.

Continuing education is essential for those who want to excel in this field to keep up with the ever-evolving cybersecurity world.
