Top Penetration Testing Methodologies to Protect Your Business
Cybersecurity threats and challenges notoriously affect small as well as large businesses. To outsmart cybercriminals, organizations need to employ ethical hacking strategies. Penetration testing is orchestrated by mimicking security attacks on a system to analyze the response and identify the vulnerabilities.
The different penetration testing methodologies and approaches used in pen testing can significantly impact the outcome. Choosing a penetration testing methodology is of prime importance as it identifies potential security weaknesses, guides the organization against evolving threats, and ensures the pen testing is organized and accurate.
In this article, we will discuss the best penetration testing methodologies and which are suitable for your business.
What Is Penetration Testing?
Penetration testing is cyber security testing to identify potential vulnerabilities in a system and mitigate their impact. Penetration testing methodology helps to understand how your system will respond to a cyber attack, build up ethical hacking strategies, and meet industry-specific compliance regulations, thus providing complete coverage of critical cybersecurity aspects. Pen tests can be carried out manually or via automated tools through a penetration testing methodology.

-
- Provides an industry standard of code review guides and frameworks
-
- Designed for WebApp
Business security use cases
OWASP’s Top 10 list, which was published in 2003 and is updated every 3 years, elaborates on the major vulnerabilities that can severely threaten the security of web applications. Testing framework, reposting, and testing methodology are the 3 sections of the OWASP Testing Guide.

4. National Institute of Standards and Technology (NIST)
National Institute of Standards and Technology is a cybersecurity framework that provides guidelines to help organizations strengthen their cybersecurity. It is a federal agency within the United States Department of Commerce that includes standards like Special Publication 800-53A Rev. 5.
Advantages
-
- It provides a common language and systematic methodology for managing cybersecurity risk.
-
- Will guide through risk management activities within various levels of an organization
-
- To assess the skill set of the testing team regarding their understanding of web apps, telecoms, networking, etc.
Business security use cases
Organizations when using NIST penetration testing should follow their pre-determined guideline. Suitable for large businesses.
-
- With the quantum resistance mathematical functions, NIST has been working to develop a post-quantum cryptography standard.
-
- Zero-trust architecture (ZTA) to protect the assets, and resources of a user within the network parameter.

Types Of Penetration Testing
1. Black Box Penetration Testing
In black box testing, the pentester is provided with little to no information about the system. From primary access to complete execution, the tester follows the steps of an unprivileged hacker that attributes to a real-world attack.
Since the tester does not have much information regarding the internal structure of the system, they will have to input a lot more work making it a costlier and time-consuming one.
Advantages
-
- Most useful to understand how a malicious actor with no knowledge of the internal structure can exploit or attack the system
-
- Demonstrates how a real-world external attack would look like
Business security use cases
-
- Identify vulnerabilities like CSRF, XSS, injection attacks, etc.
-
- Pentest the overall security of the system
2. White box Penetration Testing
In white box testing the tester is provided with all the information regarding the system and its network.
Since the testers are given full access to the system including access to network maps, documents, source code, and credentials, they help to stimulate targeted attacks on a system by using as many attack vectors as possible.
Advantages
-
- As the tester is fully aware of the internal structure of the system, it helps to save time and minimize the total cost.
-
- Expose the vulnerabilities that are often exploited by malicious actors and how this is carried out in real-time.
-
- With complete access to the system information white box testing can help you understand what an internal attack would look like
Business security use cases
-
- Penetration testing of the company’s network infrastructure and internal structure
-
- Stimulates the real-life attack on a specific system
3. Grey Box Penetration Testing
The tester is only provided with limited information about the system hence it is also referred to as translucent box testing. The partial information given to testers helps to understand the accessibility of a privileged user and the damage such privileged users can cause.
In Grey box testing When a real-world attacker probes into the targeted system, it gives knowledge similar to that of an insider.
Advantages
-
- Stimulates an insider attack as well as the data breach that occurs within the network perimeter.
-
- Since it is a combination of black box and white box testing, grey box testing has the perfect balance between efficiency and authenticity that a customer desires.
-
- Removes the time-consuming reconnaissance phase.
Business security use cases
-
- Usually carried out in public-facing websites or applications that have a private backend server, to identify vulnerabilities and remediate them.
-
- Detect vulnerabilities present in the early stage of a system and how much information an attacker can receive.
