Written by Coursera • Updated on Jul 8, 2021

Learn more about what it takes to get started in this offensive cybersecurity role.

Penetration testers, or pen testers for short, perform simulated cyberattacks on a company's computer systems and networks. These authorized tests help identify security vulnerabilities and weaknesses before malicious hackers have the chance to exploit them.

A career as a pen tester often starts with an entry-level cybersecurity position. In this article, we'll go into more detail about what penetration testers do, why this in-demand cybersecurity career could be a good fit for you, and how to get started.

What does a penetration tester do?

As a penetration tester, you'll take a proactive, offensive role in cybersecurity by performing attacks on a company's existing digital systems. These tests might use a variety of hacking tools and techniques to find gaps that hackers could exploit. Throughout the process, you'll document your actions in detail and create a report on what you did and how successful you were at breaching security protocols.

Penetration tester tasks and responsibilities

The day-to-day tasks of a pen tester will vary depending on the organization. Here are some common tasks and responsibilities you may encounter in this role, all pulled from real job listings:

• Perform tests on applications, network devices, and cloud infrastructures

• Design and conduct simulated social engineering attacks

• Research and experiment with different types of attacks

• Develop methodologies for penetration testing

• Review code for security vulnerabilities

• Reverse engineer malware or spam

• Document security and compliance issues

• Automate common testing techniques to improve efficiency

• Write technical and executive reports

• Communicate findings to both technical staff and executive leadership

• Validate security improvements with additional testing

In this video, we'll discuss what penetration testing or pentesting is and why it's important.

Where do penetration testers work?

Penetration testers typically work in one of three environments.

• In-house: As an in-house penetration tester, you work directly for a company or organization. This typically allows you to get to know the company's security protocols well. You may also have more input into new security features and fixes.

• Security firm: Some organizations hire an outside security firm to conduct penetration testing. Working for a security firm offers greater variety in the types of tests you'll get to design and perform.

• Freelance: Some penetration testers choose to work as freelancers. Choosing this path can give you greater flexibility in your schedule, but you may need to spend more time looking for clients early in your career.

Penetration testing vs. ethical hacking

The terms penetration testing and ethical hacking are sometimes used interchangeably in the cybersecurity world. But the two terms have slightly different meanings. Penetration testing focuses on locating security issues in specific information systems without causing any damage. Ethical hacking is a broader umbrella term that includes a wider range of hacking methods. You can think of penetration testing as one facet of ethical hacking. Both roles have overlap with a cybersecurity Red Team—the group that gives security feedback from the adversary's perspective.

How to become a penetration tester

As a penetration tester, you can earn a paycheck by legally hacking into security systems. It can be a fast-paced, exciting job if you have an interest in cybersecurity and problem solving. In this section, we'll take a closer look at the steps you might take to get your first job as a penetration tester.

1. Develop penetration testing skills.

Penetration testers need a solid understanding of information technology (IT) and security systems in order to test them for vulnerabilities. Skills you might find on a pen tester job description include:

• Network and application security

• Programming languages, especially for scripting (Python, BASH, Java, Ruby, Perl)

• Threat modeling

• Linux, Windows, and MacOS environments

• Security assessment tools

• Pentest management platforms

• Technical writing and documentation

• Cryptography

• Cloud architecture

• Remote access technologies

Popular penetration tester tools

Today's penetration testers have a range of tools to help make their jobs faster and more efficient. If you're interested in becoming a pen tester, it can help to gain familiarity with one or more of these tools.

*Kali Linux: Popular pentesting operating system

*Nmap: Port scanner for network discovery

*Wireshark: Packet sniffer to analyze traffic on your network

*John the Ripper: Open-source password cracker

*Burp Suite: Application security testing tools

*Nessus: Vulnerability assessment tool

*OWASP ZAP Proxy: Web application security scanner

Get hands-on experience with some of these tools in two hours or less with a Guided Project on Coursera. Start with Wireshark for Basic Network Security Analysis or Web Application Security Testing with OWASP ZAP.

2. Enroll in a course or training program.

One of the best ways to start developing the skills you'll need as a penetration tester is to enroll in a specialized course or training program. With these types of programs, you can learn in a more structured environment while building multiple skills at once.

If you're new to cybersecurity, consider an option like the IBM Cybersecurity Analyst Professional Certificate, which includes an entire unit on penetration testing and incident response. The entire program is online and at your own pace, so you can learn job-ready skills while working or managing life's other responsibilities.

Do I need a degree to become a penetration tester?

While it can be helpful to have a degree in computer science, information technology, or cybersecurity, not all penetration testing jobs require a degree. Typically, your level of experience and ability to complete the task matter more than what degree (if any) you have. If you're starting in cybersecurity without a related degree, it might be helpful to pursue a certification to validate your skills.

3. Get certified.

Cybersecurity certifications demonstrate to recruiters and hiring managers that you have the skills required to succeed in the industry. In addition to these more general cybersecurity certifications, you can also get certified in penetration testing or ethical hacking. Reputable certifications to consider include:

• Certified Ethical Hacker (CEH)

• CompTIA PenTest+

• GIAC Penetration Tester (GPEN)

• GIAC Web Application Penetration Tester (GWAPT)

• Offensive Security Certified Professional (OSCP)

• Certified Penetration Tester (CPT)

Earning one of these certifications generally requires passing an exam. Besides earning a credential for your resume, preparing for a certification exam can often help you develop your skill set as well.

4. Practice in real and simulated environments.

Many companies want to hire penetration testers with previous experience. Luckily, there are ways to start gaining experience outside of the workplace. Many pen testing training programs include hands-on testing in simulated environments.

Another way to gain experience (and make your resume stand out) is to participate in bug bounty programs. In these programs, companies typically offer cash bonuses to independent pen testers and security researchers who find and report security flaws or bugs in their code. It's an excellent way to test your skills and start networking with other security professionals. You can find a list of bounties on sites like Bugcrowd and HackerOne.

Finally, you'll find several websites designed to allow penetration testers to legally practice and experiment through fun, gamified experiences. Here are a few to get your started:

• Hack the Box

• Hack.me

• Hack This Site

• WebGoat

5. Start in an entry-level IT position.

Many penetration testers start out in more entry-level IT and cybersecurity roles before advancing into pen testing. If you want to pursue a career in pen testing, consider starting out in a role like network or systems administrator or information security analyst to start building your IT skills.

6. Begin your job search.

When you're ready to begin applying for pen tester jobs, be sure to extend your search beyond the usual job sites. While LinkedIn, Indeed, and ZipRecruiter are excellent resources, you should also scan specialized cybersecurity job boards, like Dice and CyberSecJobs.com.
