The way has never been easy, but you can reach it if others have. But it depends on the energy and effort you are going to put into it.

Before we continue with this article, let us first see what penetration testing really is. because some are having confusion about penetration testing and ethical hacking.

What is penetration testing?

Penetration testing is a type of security testing that is used to test the security of an application. It is conducted to find a security risk that might be present in a system.

When a system is not secure, then it’s easy for an attacker to get into it. Security is normally an accidental error that occurs while developing a system.

why is penetration testing important?

You must understand that penetration testing is very important to ensuring system or network security. Also, penetration testing normally must evaluate the system’s ability in order to be protected.

Also, penetration testing must assure that only external or internal authorized users can access the system.

Then, penetration testing is important because:

  • It provides evidence to suggest why it is important to increase investment in the security aspect of technology
  • also, it estimates the volume of the attack
  • It supports avoiding black hat attacks and also protects the original data.
  • helps also to detect the weakness of the system

Pay attention: penetration testing necessitates not only knowledge of the tools used to test, but also knowledge of how to use them. But a real penetration tester must be able to proceed rigorously and detect the weaknesses of a system.

They must be able to identify the technology behind them and test every single door that might be open to attackers.

Also, it is important to inform yourself about the law and what you are allowed to do or not. According to the laws of your country, the computer laws are not the same.

First, check laws about privacy and surveillance: Nine eyes countries, Five eyes, and Fourteen Eyes. Always check if what you’re doing is legal. Even when it’s not offensive, information gathering can also be illegal!

The penetration tester not only discovers vulnerabilities that could be used by attackers. But also must be able to exploit those vulnerabilities, to assess what attackers might gain after a successful exploitation

How is penetration testing Beneficial?

While the practice of penetration testing is growing in popularity, it comes with benefits.

Identify and resolve system vulnerabilities: Penetration testing is when penetration testers put themselves in a hacker’s position. By staying on the pulse of the cybersecurity world and regularly approaching IT systems from a cybercriminal’s perspective, penetration testers can identify a wide range of vulnerabilities and weaknesses in the system.

Gain valuable insights into digital systems: Reports from penetration testing can provide valuable details about the network or system, its weak points, and how to strengthen it.

Establish trust with your clientele: A cyberattack or data breach negatively affects the confidence and loyalty of your customers, vendors, and partners.

Protection from financial damage: A simple breach of a security system may cause millions of dollars of damage. Penetration testing can protect the organization from such damages.

some vocabulary related to penetration testing

A penetration tester: is an ethical hacker who practices security and tests applications and systems to prevent intrusions or find vulnerabilities.

Reverse engineering: Reverse engineering, also called back engineering, is the process by which a man-made object is deconstructed to reveal its designs and architecture, or to extract knowledge from the object.

similar to scientific research, the only difference is that scientific research is about a natural phenomenon.

Social engineering: In the context of information security, it refers to the psychological manipulation of people into performing actions or divulging confidential information.

Security researcher: Someone who practices pen testing and browses the web to find phishing/fake websites, infected servers, bugs, or vulnerabilities.

They can work for a company as a security consultant and are most like a Blue team.

Penetration tester skills required

A penetration tester must be able to modify existing exploits in order to make them work in specific networks for testing purposes. But no single tester can possibly be an expert across all domains, but they need to be active learners and develop real-world experiences.

Understanding of secure web communications and technologies

You need an understanding of web technologies. Web applications are a well-accepted portion of just about every assessment we do these days, and everybody needs to understand them.

Our assessors need to know how web applications are built, how to identify input fields, and how to gather the information that can lead to exploiting the functionality of the web application.

Ability to Script or Programming

Learning programming is the very first way to start learning about security. There are a lot of languages, most people start with Python, which is the easiest and most popular one.

PHP and Go are the less popular to write security-related stuff, but any of these can still be used in such a context. Bash and PowerShell are mostly about scripting and writing simple CLI applications.
