What is Penetration? How to perform effective penetration testing

Penetration testing is an important keyword in the field of information security. But do you fully understand the process and importance of performing penetration testing?

Therefore, in the article below, AZCoin will help you better understand penetration testing, implementation methods and why it’s necessary to protect your system.

What is penetration?

Penetration, also known as penetration testing, is the process of evaluating the security of a computer system, network or application by simulating external attacks. The main goal of penetration testing is to identify security vulnerabilities that hackers can exploit to gain access to the system. This process not only helps to detect weaknesses but also provides recommendations for improving security.

History of penetration testing

Penetration testing has a long and continuous history. The concept emerged with the development of computer and network technology. Initially, security testing methods were performed by performing actual attacks to detect vulnerabilities. In the late 1970s and early 1980s, companies and organizations began to realize the importance of formal security testing. 

In the 1990s, as the Internet and network systems became more popular, performing penetration testing became an important part of organizations’ security strategies. The security industry has been growing with advanced tools and methods to improve the pentesting process.

Penetration testing methods

Below are some common methods in penetration testing:

External Test

External testing is a pentesting method that focuses on system components that are accessible to external users, such as web servers or public network services. It’s a way to test a system from the perspective of an external attacker to assess the security level of the system when facing external attacks.

Internal Test

Internal testing is performed in the organization’s internal network environment. This is a method of testing systems, servers and networks from within the organization, to identify vulnerabilities that an attacker could exploit if he had access to the internal system. This method helps ensure that internal security measures are effective.

Blind Test

A method in which the testing team receives very limited information about the target system before starting. This helps simulate a situation where the attacker has no detailed information about the system, thereby assessing the system’s real response and defense capabilities. Blind testing allows for the detection of vulnerabilities that may be overlooked in normal situations.

Double Blind Test

Double blind testing is an even more rigorous form of pentesting. Both the testing team and the internal security team are unaware of the timing and details of the test. This method helps assess the system’s readiness for attacks without prior preparation, thereby providing a realistic view of the organization’s protection capabilities.

Target Test

Target testing is a test that focuses on a specific target or a specific part of the system. Experts conduct detailed attack techniques to identify vulnerabilities specific to the chosen target, helping the organization understand potential weaknesses in its system. This method provides insights into how specific components of the system might be vulnerable to security breaches.

Why need penetration testing?

Penetration testing is an essential part of a comprehensive security strategy for the following reasons:

• Detecting security vulnerabilities: Pentesting helps identify weaknesses in a system that hackers can exploit.
• Assessing security adequacy: Testing the effectiveness of current security measures and their ability to respond to attacks.
• Complying with regulations: Many industries require organizations to perform pentesting to meet security standards and regulations.
• Enhancing security: Providing recommendations and solutions to improve security systems.

How to perform effective penetration testing

To conduct an effective penetration testing, you can follow these steps:

• Target survey: Collect data about the system, network, application to be tested. This includes identifying assets, services and potential vulnerabilities.
• Information gathering: Use tools like WHOIS and Google Dorks to gather publicly available information about the target system. This data includes IP addresses, domain names and network topology.
• Security scanning: Perform a security scan with tools like Nessus to detect security vulnerabilities. Assess issues related to the system’s configuration, software and services.
• Analyze results: Evaluate the severity of the discovered vulnerabilities and identify potential risks. This analysis helps identify the most serious issues that need to be fixed first.
• Attack execution: Use exploitation techniques to test the discovered vulnerabilities. This allows you to assess the severity of the vulnerabilities and the likelihood that they could be exploited in the wild.
• Impact assessment: Examine the impact of attacks on the system to better understand the risks and potential losses.
• Generate detailed reports: Prepare detailed reports of the findings, including descriptions of the vulnerabilities, how they were exploited and their impact. The report should be easy to understand and specific so that stakeholders can take remedial actions.
• Make recommendations: Provide recommendations and solutions to address security vulnerabilities. This includes suggesting new security measures and improving current security processes.
• Track remediation implementation: Ensure that remediation measures have been effectively implemented and that the system is free of the discovered vulnerabilities.
