Penetration tester job description
Where we source our data
Let’s get real. Job information online can often be overly optimistic — conveniently glossing over the raw bits. But when you’re making decisions about your future, you need all the facts.
That’s why we anonymously surveyed penetration testers about their job, with hopes of getting an honest insight into what it’s really like.
While we did our best to ensure respondents were Australians and verified their job titles with proof of employment, we can’t guarantee complete accuracy — or that your experiences in the field will reflect theirs. So, we suggest that you take these insights as a guide only and try to talk to people in the field before making an important decision.
Tasks and responsibilities for a penetration tester
A penetration tester’s responsibilities include:
- Conducting penetration tests to identify vulnerabilities in computer systems, networks, and applications.
- Exploiting identified vulnerabilities to gain unauthorised access (with proper authorisation) and assess potential risks.
- Performing thorough assessments of security controls, architecture, and infrastructure.
- Generating detailed reports that outline discovered vulnerabilities, their impact, and recommendations for remediation.
- Collaborating with stakeholders to implement security measures and ensure compliance with industry standards.
- Staying updated with emerging hacking techniques, security threats, and defensive strategies.
- Participating in incident response activities to analyse and address security breaches.
How to become a penetration tester
-
Study a relevant penetration tester course
While a formal education is not always mandatory, it can provide a strong foundation. Consider pursuing a degree in computer science, cybersecurity, information technology, or a related field. Alternatively, you can focus on obtaining industry-recognised certifications such as Certified Ethical Hacker (CEH), CompTIA PenTest+, and or a Certified Information Systems Security Professional (CISSP).
-
Build your technical knowledge
Develop a solid understanding of networking protocols, operating systems, web technologies, and programming languages. Take courses or engage in self-study to gain expertise in these areas. Familiarise yourself with concepts related to ethical hacking, vulnerability assessment, and penetration testing methodologies.
-
Get practical experience
Practical hands-on experience is essential. Look for opportunities to work on real-world projects, participate in capture-the-flag (CTF) competitions, or engage in bug bounty programs. Building a portfolio of practical projects and accomplishments will demonstrate your skills and dedication to potential employers.
-
Learn penetration testing tools
Familiarise yourself with popular penetration testing tools such as Metasploit, Burp Suite, Nmap, Wireshark, and others. Learn how to effectively use these tools to identify and exploit vulnerabilities. Practice using them in controlled environments and simulated scenarios.
-
Job search and career development
Look for entry-level positions or internships that offer opportunities to work as a penetration tester. Gain practical experience in a professional setting and continue to develop your skills. As you progress, aim for mid-level and senior positions that allow you to take on more challenging projects and responsibilities.
