Penetration testers help companies and organizations identify and repair security bugs in their digital assets and computer networks
some testers work in-house for permanent employers and internal cybersecurity or information technology (I.T.) teams. Others work as a freelancer for specialist companies that provide penetration-testing services to their clients.
With the high-profile security breaches dominating the cybersecurity landscape, now is an excellent time to become a penetration tester.
As cyberattacks become more sophisticated and nuanced, online companies’ chances of falling prey to cybercriminals are increasingly rising-which is why organizations need penetration testing.
Penetration testers are engaged in more significant numbers across industries that deal with large volumes of confidential, medical, classified, or proprietary data.
Some firms put a higher value on a candidate’s expertise and experience than on their academic credentials.
Organizations are seeking candidates with a bachelor’s or master’s degree in computer science, information technology, cybersecurity, or a related field of experts.

Penetration tester: Who is one?
The investigators of the information security world are penetration testers/ethical hackers. The aim, as with many P.I. operations, is to discover threats before any possible invasive operators can put their plans into action.
One of the elementary truths of human existence in general, and digital information systems in particular, is that unscrupulous actors will always try to exploit vulnerabilities.
Pen testers look for possible bugs in wired and wireless network systems, as well as web-based software, to analyze, discover, and help fix them.
A perpetual arms race exists between ethical hackers’ proactive actions and the efforts of real-life hackers. Each side makes a concerted effort to advance its expertise, skills, and strategies beyond the other’s capabilities.
Penetration testers use an aggressive defensive technique. The motive is to provide the best possible information security by targeting computer systems offensively in the same way that a real-life hacker would, thereby beating the hacker to the punch and assisting in the closure of the vulnerability.
As a consequence, information security will be compromised, and networks will be targeted- so that the real-life hackers can be beaten in their own game.
Pen tester: How to become one?
The position of a penetration tester screams a great deal of responsibility. You will be expected to be well-versed in cybersecurity tactics, threat styles, and vectors.
Since the cybersecurity world is one of the most complex and ever-changing in the Information Technology world, one needs to be ready to keep your skills up to date on a regular basis.
This means you’ll need a strong interest in cybersecurity and a willingness to learn new things on a regular basis.
You must have a thorough understanding of I.T. applications and networks. Understanding communication protocols is also crucial since this can be a system’s weak point.
This implies that knowing how to write software code is advantageous. It is not required, and you do not need to be an expert, but having hands-on knowledge of THE HOT programming language such as Python would be beneficial.
Kickstarting your career: as a Penetration Tester!
Whether you’re a beginner or a seasoned I.T. pro interested in learning more about pen testing, you should start by reading up on the topic.
Using blogs, textbooks, and guides, as well as videos, to learn more about not only pen testing but also general cybersecurity issues.
The bottom line is, that you should be aware of the following:
- Techniques, tricks, pathways, threat profiles, and the anatomy of cyberattacks are all covered in this section on cybersecurity.
- For cybersecurity intelligence, the OWASP website can turn out to be a good teacher.
- Networks and hardware
- Databases, operating systems
- Web apps and APIs-some hands-on knowledge on these applications.
- At least in terms of analyzing security problems and proposing solutions, data analysis is essential.
Pen Testing: Hands-on Experience!
As with most I.T. jobs, there is no one-size-fits-all skillset for a pen tester. Some penetration testers are self-taught and lack academic qualifications and certifications.
By cultivating the right skills and hustling a little, you could become one with the right combination of talent and opportunity.
Penetration testing is a practical subject in the field of I.T. All the books and YouTube videos on ethical hacking in the world cannot prepare you for the real thing.
You’ll need to practice. If you’ve read this far, there’s a good chance you’ll be one of the people who can quickly put your own mini-test system together.
Pen testing toolkits like Security Onion or Kali Linux will help you get started on your own pen-testing for practice. They have a condensed collection of pen testing methods that can be used to get a feel for the practical side of pen-testing.
One must learn about the Penetration Testing Execution Standard (PTES), which is a pen testing system.
It will assist you in achieving operational standards and serve as a practical general guide in the field. Many job roles and internships will enable you to be well-versed in both this standard and OWASP.
Gaining Further Experience: Diving Deeper
You’ve had a few years of technical experience now. At work, you may have already begun to take on security responsibilities. You now have a Kali case, 600 new tools, and a nagging trigger finger.
The following is a disclaimer: attempting to obtain unauthorized access to a device is against the law.
With that out of the way, hands-on experience is critical when learning any new skill, but it’s especially important when learning penetration testing. As previously mentioned, penetration testers:
- Find out what the weaknesses are
- Determining attacks may take advantage of those flaws
- Understand how to use the tools to carry out the attack
- A summary of how to fix the flaw
- There’s no better way to understand these than by doing them.
Pen testing Bootcamps to sharpen yourself: There’s no better way to learn and practice penetration testing than under the supervision of an instructor.
The penetration research curriculum is built around lab environments in cybersecurity boot camps like QuickStart.
Penetration monitoring is challenging. In as little as five days, qualified teachers will teach you the fundamentals of penetration testing.
Accustoming yourself to the Lab Environment: There is a slew of great penetration testing lab items on the market.
Training companies create lab environments to build tasks that replicate common vulnerabilities found in the wild.
Hack the Box, which CONSISTS OF free and paid tiers of A PLETHORA OF pen-testing challenges, is the most common lab environment for aspiring pen testers.
The Hack the Box challenges range from easy to difficult, and new challenges are introduced on a regular basis. Hack a Box is a group of scores, badges, and prizes in addition to the challenges.
Although H.T.B. isn’t the only lab environment available, it’s open, community-oriented, and often the first stop for new pen testers — a good place to start.
Gripping on the Flag Competitors: Cybersecurity Competitions such as Capture the Flag (CTF) are simply gamified lab settings. CTF competitors are given a “flag,” which may be a piece of data or a certificate in a lab setting, much like in the kid’s game.
You must complete a set of increasingly difficult tasks that fall into five categories in order to “capture” the “flag.”
- The exploitation of binary data
- Reverse engineering is the process of reconstructing the existing object with deductive reasoning
- The exploitation of the internet
- Cryptography is a technique for encrypting.
- forensic science
- A variety of free capture the flag competitions are available. Smash the Stack, and Google CTF are two of the most common online CTF competitions.
Start exploring your own network: Finally, start playing around with enumeration tools like Nmap and Burp Suite.
It’s not a bad idea to run port and vulnerability scans on your own network, whether at home or at work. It’s possible that you’ll be shocked by what you find.
That being said, don’t start aiming Kali’s manipulation resources at something you don’t own — or don’t want to destroy. Kali Linux is a versatile collection of tools that can lead to trouble.
There are lab settings, boot camps, and this site: Hack This Site, which is exactly what it sounds like- if you really want to hack something.
Penetration Tester-Job Roles & Responsibilities:
Penetration testers, otherwise known as ethical hackers, are people who search for and record security flaws.
This is normally achieved under the parameters set out in a client-pen tester agreement. Such boundaries may be set by a deadline, such as exposing weaknesses in their network in a matter of days.
Before we go any further, the last point should be emphasized: specifying the scope of work is a must if you’re going into pen research.
Pen testers were recently arrested in Iowa for burglary and possession of burglary equipment. The state government hired the testers, and they were caught breaking into a courthouse.
If you’re just starting out as a pentester, make it a habit to spell out the scope of work in written agreements. Let’s get back to the duties of a pen tester now that that’s out of the way. The contracting company receives a report after the testing process is completed.
In general, the report will list vulnerabilities, attempt to measure their seriousness and recommend remediation measures.
For example, a phishing email could have revealed a lack of user awareness and knowledge. In that case, end-user training and applications such as KnowBe4 might be recommended.
The following are examples of activities that come under the umbrella of pen testing responsibilities:
- Port scanning and network vulnerability
- Attacks based on social engineering
- Penetration checks for physical security
- Creating a report
- Making suggestions for remediation
It might be difficult to comprehend that a company would want others to try to compromise their network at first.
It would make sense, though, if you consider it from the viewpoint of a long-term, responsible company. Who would you like to have found a security flaw: a pentester you hired or a malicious attacker?
