How to become a Penetration Tester

Penetration Tester – A penetration test, or “pen test,” is a way to check the security of an IT system by safely exploiting flaws. This issue could be found in operating systems, services, apps, or how people interact with these systems and applications. They could also result from incorrect setups or unsafe behavior on users. Such tests can also be used to make sure that defenses work and that users follow security rules.

What is Penetration Tester?

Penetration testing is usually done with manual or automated tools to get into servers, endpoints, web applications, wireless networks, network devices, mobile devices, and other places where hackers could get in. Once a vulnerability has been exploited on a system, testers may use the compromised system to launch more attacks on other internal resources, such as gaining more security clearance and deeper access to electronic assets and information through privilege escalation.

Information about any security flaws that were successfully exploited during penetration testing is usually gathered together and presented to IT and network system managers. This helps them make strategic decisions and prioritize remediation efforts. The main goal of penetration testing is to find out how easy it is for systems or users to be hacked and how these incidents might affect resources or operations.

Penetration Tester Career Guide

There are a lot of people who want to be penetration testers. This might be the right job if you know a lot about doing pen tests and vulnerability assessments, exploiting systems, and communicating your findings.

There are many ways for an IT person to become a penetration tester. So how do you know what to do? Unfortunately, there is no single answer. Pen testers come from all different types of jobs. It doesn’t matter if they’re network administrators or engineers, system or software developers, graduates with IT security degrees, or even hackers who learned to do it independently. Even if the professional already has skills and knowledge, all pen testers need to get the right mix of formal knowledge and hands-on experience to succeed in their job. In addition, they need to be trained, desire to stay up to date on new technology and stay one step ahead of hackers.

“Ethical hackers” use their skills and knowledge to look for holes in computer systems. They also get paid to do the digital equivalent of breaking into a computer.

Some of the tools and procedures they employ to imitate real cyber-attacks are made up by them. In addition, they leave no stone unturned to find holes in security protocols for networks, systems, and web-based applications.

A penetration test, or “pen test,” aims to find security flaws before they can be exploited by real hackers. This way, they’ll be able to catch them before they get inside. Because pen testers often work on confidential and time-sensitive projects, they need to be trustworthy and cool under pressure.

Pen testers are in high demand because there are not enough people who are good at this job. You’ll find useful information in this article about possible jobs and ways to learn if you’re interested.

What does a Penetration Tester do?

Pen testers often analyze threats, assess security, and ethical hack networks, systems, and online applications. Assurance validation includes any or all of the following tasks:

  • Gather and evaluate OSINT for information disclosures.
  • Provide subject matter expertise in offensive security testing, helping to test an organization’s protective measures.
  • Evaluate a diverse range of technologies and implementations using automated and manual tools.
  • Create scripts, tools, and procedures to improve testing.
  • Would you please assist with scoping new engagements, taking them through implementation and remediation?
  • Conduct social engineering and penetration testing.
  • Examine wired and wireless networks for flaws.
  • Examine assessment data to generate a complete analytic view of the system in its context.
  • Resolve technical and non-technical issues.
  • Publish an Assessment Report detailing results and possible countermeasures.

How to become a Penetration Tester?

Penetration testers are “ethical hackers” or “nice guys.” Security penetration testers, also known as assurance validators, are recruited by network system owners and web-based application providers to search for vulnerabilities that malevolent hackers could exploit to steal sensitive data and information from their systems.

Ethical hackers use their skills and knowledge to undertake vulnerability assessments (among other things) and are compensated for performing the equivalent of digital break-ins.

Various tools and methodologies are used to simulate real cyber-attacks, some of which they have built themselves. In addition, they leave no stone unturned in their pursuit of security holes in network, system, and web-based application security protocols, which they believe are widespread.

Step 1: Obtain a Bachelor’s Degree

Penetration testers might be hired without a specialized degree if they have relevant hacking abilities and work experience. However, many pen-testing professions demand a bachelor’s or master’s degree in cyber security, computer science, or information technology.

Computer science or IT degree programs cover operating systems, programming languages, network tools, and computer hardware and software. Specialized coursework in encryption, forensics, vulnerability analysis, and security frameworks and technologies is also available through cybersecurity-focused programs.

Step 2: Acquire Knowledge

Pen testing positions typically require 1-4 years of expertise in information security, with higher-level positions requiring 3-10 years of experience in vulnerability assessment or network penetration testing. Penetration tester positions at the entry-level often require 1-4 years of prior work experience in IT activities such as system administration, security administration, network administration, or network engineering.

Many penetration testing professions also demand professional experience in penetration testing, vulnerability assessment, or information security due to the expertise required to break into information systems.

Furthermore, recent graduates and professionals frequently use appropriate internships or IT support positions to qualify for entry-level positions. Internships are common in many degree programs, allowing students to network, gain mentors, and develop real-world information security skills.

Step 3: Develop the Required Skills

Penetration testers require both technical and analytical skills to detect security flaws. In addition, these experts require creativity and problem-solving skills to develop tools for breaking into security systems or developing new solutions. Pen testers must also understand computer security, including forensics, system analysis, and the coding abilities required to breach networks.

Step 4: Obtain Certification 

Aspiring penetration testers can obtain skills through online courses and certification programs such as ECSA. Many roles require certificates and the penetration mentioned above: education and work experience. The most common qualifications required are extensive security certified professional, certified penetration tester, and certified expert penetration tester. Several cybersecurity-related certification alternatives are available from professional organizations, technological businesses, and online colleges, so do your homework.

How to Find Penetration Tester Jobs?

“Tom Cruise in ‘Mission Impossible’ hacking into a CIA computer while dangling horizontally from wires in a heavily fortified room,” according to a DarkReading article (“So You Want to Be a Penetration Tester”).

Starting as a programmer or systems administrator will teach you so much about how systems work that spotting weaknesses will become second nature. Practical experience is stressed.

“The beginning is the evaluation, the middle is the exciting part like getting into a system, and the finish is the documenting and transmitting those results to a client,” says security expert David Maynor. Nobody does pen testing well unless they accomplish all of those things.”

Most of the work is done from home for penetration testing consultants, but there is also a significant amount of travel to and from project locations.
