How to become a Penetration Tester

If you’re wondering how to become a penetration tester, the good news is that you don’t need to have a relevant Bachelor’s, Master’s degree, or any degree at all, for that matter — many people enter the field without one.

Read on to learn more about what a pen tester does, as well as any skills, education, and certifications that are required or helpful for securing work. We’ll also cover the latest information about penetration tester salary expectations and where to find the top jobs.

What is penetration testing?

Penetration testing essentially involves an authorized simulated cyberattack, with the aim of finding out how to improve the security of the system. A penetration tester wants to find holes in a system before a hacker can.

Penetration testing aims to prevent ‘black-hat hacking,’ which involves breaking into a system with malicious intent. The intention of a black hat hacker might be to install malware, hold computers hostage, or steal passwords, credit card numbers, or other private information.

A penetration tester will carry out a simulated version of these activities by breaching a number of application systems, such as application protocol interfaces (APIs) and frontend/backend servers. This process can be completed manually or using automated software. Penetration testing provides insights that can then be used to fine-tune security, preventing unethical hacks from taking place.

A penetration tester will often carry out an ethical hack in a five-step process:

  1. Planning: This involves defining the test goals and gathering intelligence.
  2. Scanning: A penetration tester employs scanning tools to understand how a target responds to an intrusion.
  3. Gaining access: A pen tester stages web application attacks to uncover a target’s vulnerabilities.
  4. Maintaining access: An advanced persistent threat (APT) (a prolonged and targeted cyberattack) is imitated to see if a vulnerability can be exploited to maintain access.
  5. Analysis and WAF configuration: A penetration tester uses the results of his or her simulated cyberattack to configure web application firewall (WAF) settings before testing is run again. This process is repeated until the system is secure.

What does a penetration tester do?

Your exact role as a penetration tester will depend on the organization you work for, as well as your title and the level of seniority of your role. Nonetheless, here are some of the tasks you may see included in a penetration tester job description:

  • Gathering and analyzing open source intelligence (OSINT) – information from public sources – to find information disclosures (when an application reveals sensitive information).
  • Providing expertise on security and testing defensive mechanisms for the organization.
  • Conducting assessments on a wide range of technologies, using both automated tools and manual approaches.
  • Developing scripts, tools, and methodologies to improve testing processes.
  • Testing both wired and wireless networks for any security vulnerabilities.
  • Examining results from the assessment to identify findings and develop a holistic view of the system.
  • Identifying the root cause of both technical and non-technical findings.
  • Publishing a report that documents the findings from the assessment while identifying potential countermeasures.
  • Keeping track of and communicating findings from multiple assessments.
  • Communicating the methods used to complete assessments.
  • Providing technical support in the organization.

There are many useful tools that penetration testers use to carry out their tests. These include Kali Linux, nmap, Metasploit, Wireshark, and John the Ripper, all of which are designed to help pen testers find weaknesses in a system.

What skills are required to become a penetration tester?

Just like with other fields of cybersecurity, penetration testing requires a specific skill set. Based on the duties that a penetration tester will carry out you can expect to need the following core skills:

  • Knowledge of vulnerabilities outside of tool suites. This means being able to detect vulnerabilities without relying on tools such as Metasploit. As a penetration tester, you don’t want to be helpless if you can’t use a certain tool. The best penetration testers don’t just copy what vulnerability scanners say.
  • In-depth understanding of secure web communications and technologies. You need to understand the ins and outs of web communication and technology as well as – and preferably better than – any unethical hacker.
  • The ability to write code.

Aside from these core hard skills, there are also various soft skills that a penetration tester will need, such as:

  • Attention to detail
  • Analytical skills
  • The ability to think creatively and strategically
  • Ethical integrity (so you can be trusted to deal with confidential information)
  • Being a team player
  • Excellent written and spoken communication such that you can explain your methods to both a technical and non-technical audience
  • Good time management and organizational skills including the ability to meet deadlines

Aside from the above, you need to be an active learner who stays up to date with the latest technology and black-hat hacking techniques. To ensure no security breaches take place, you should always be eager to refine your skills and stay one step ahead of threat actors.

How to become a penetration tester

So, you’ve decided that a pen tester is an appealing career path, but what are the necessary steps to actually obtaining a role in this field? We have devised five steps you should take in order to make this career path a reality.

Here’s how to become a penetration tester:

  1. Devise a plan
  2. Consider earning a degree
  3. Scope out certifications
  4. Conduct a job search
  5. Extend your learning

Let’s explore these steps in more detail:

1. Devise a plan

Even if you know that you want to become a penetration tester, you still need a career plan. First, you need to map out how to get started including becoming adept at penetration testing skills, either through self-education or formal education.

Next, you may want to think about whether you want to work for a private firm or a government organization. And of course, both private firms and government organizations cover a wide range of areas, such as education, finance, energy, transport, environment, and so on.

It’s also worth thinking about what area of penetration testing you want to get involved in, as this career area has many subsets and specializations. Once you’ve chosen a particular career path aligned with your values, interests, personality, and goals, you should find out what the requirements are for that position. You can contact recruiters directly to enquire if any qualifications are required or preferred.

2. Consider earning a degree

As mentioned previously, it is not necessary to earn a degree to become a penetration tester. Many people, such as those who used to engage in unethical hacking, taught themselves how to hack. There are plenty of resources and tools online that can assist you in this self-education. With enough practice on your own, you can be ready for an entry-level – or even a higher level – penetration testing position.

On the other hand, a relevant degree can also be incredibly useful in giving you the knowledge and skills to carry out penetration testing. It can be a way of learning the skills more efficiently and gaining insights you might miss through self-education. Studying under the direction of experienced professors, as well as alongside other students, can be greatly beneficial.
