A Beginners Guide to Black Box Penetration Testing & Its Impacts

This article talks about black box penetration testing, the basic concepts behind it & what are practical applications in the current software industry. Read till the end to learn everything about this testing type.


Penetration testing in the current software industry comes in many different variants & can examine applications, Wi-Fi, network services, & physical assets. These could involve testing of internal & external infrastructure, testing of online or mobile applications, testing of APIs, reviewing the configuration of clouds & networks, performing social engineering, & even testing of physical security.

To give you all the details you need to choose the best pen test for your organization, this article makes an effort to cut through industry jargon. This includes answering the what is black box penetration testing & another crucial question of whether you need a black box, white box, or grey box testing style.

What is Black Box Penetration Testing:

Black-box penetration testing a.k.a pen-testing describes external tests designed to find weaknesses in networks, applications, or systems. Penetration testing, in contrast to other types of security testing, may confirm that vulnerabilities are exploitable by attackers and demonstrate how. External penetration testing, trial-and-error testing, & black-box penetration testing are other terms for the same practice. 

It is a type of penetration testing that focuses on finding & exploiting system vulnerabilities from the outside. Before the testing, the security expert is not given any knowledge of the target system. Except for the destination URL & (maybe) access akin to an end user. This indicates that before testing, the tester has no access to internal data, source code (aside from publicly available code), the structure, or the architecture of the application. This type of architecture comes with many direct advantages including:

1. Uses social engineering approaches to identify human-related security problems.

2. Simulates an artificial attack to find unexpected outcomes.

exposes flaws, & finds them.

3. By evaluating the application during runtime, implementation, & configuration errors are found.

detects improper product builds, including outdated or missing modules & files.

4. Identifies security flaws brought on by interactions with underlying environments, such as incorrect configuration files & unhardened operating systems.

5. Locate errors, such as input or output validation errors & information disclosure in error messages.

6. Searches for common flaws including SQL injection, XSS, & CSRF. 

examines potential server configuration issues. 

7. Provides thorough remediation information to assist in problems being fixed promptly.

But this technique also comes with cons which are:

1. A black-box penetration test does not provide a thorough analysis of your internal systems & source code. 

2. When this test finds problems, it means the target's security build is inadequate. A black-box penetration test, however, cannot ensure that the target is secure. The target could still be struggling internally, behind the surface.

3. It relies on the trial-and-error of the outside contractor hired to conduct the test it is carried out on. 

4. The penetration test may be brief & conclude when vulnerabilities are found, or it may need months of research before one vulnerability is found. The time frame of the test is set according to the penetration tester's experience & other factors.

Which is better: Black Box, White Box, or Grey Box Testing?

In a black box penetration test, the tester receives absolutely no information. In this case, the pen tester mimics an unprivileged attacker's strategy from initial access & execution until exploitation. The most realistic scenario is this one since it shows how an opponent without inside information would target and compromise an organization. However, because of this, it is frequently the most expensive choice.

White box penetration testing, also known as crystal or oblique box pen testing, entails providing the tester with complete network and system details, including network maps and credentials. This contributes to time savings and lowers the overall engagement cost. A white box penetration test helps simulate a targeted attack using as many attack paths as feasible on a particular system.

Very little information is shared when a grey box penetration test is being carried out by a tester, that is why sometimes called a transparent box test. This information being shared is typically in the form of login information. This test assesses the degree of access & potential harm that a privileged person could have. To simulate an insider threat or an attack that has breached the network perimeter, grey box tests find a balance between depth and efficiency.

A persistent enemy will typically do reconnaissance on the target environment before an attack, giving them access to information that an insider would have. Customers frequently choose grey box testing because it eliminates the potentially time-consuming reconnaissance phase while maintaining authenticity and providing the optimum efficiency-authenticity ratio.

Finding the right blend and routine of pen testing is extremely important in the software development and testing routines and this is where WeTest has tons to offer. A software industry's veteran team and software solutions made with efficiency and crystal-clear tests in mind, WeTest puts itself in a position of top-tier software testing services in the current industry. 

Wrapping Up: 

This article talked about black box penetration testing, its pros and cons, and its comparison with white box, black box, and black box pen testing. The methods used to simulate a hacker's attack on a network, find vulnerabilities, and fix them include black, gray, and white box penetration test. Black-box penetration testing is ideal because they most precisely mimic how hackers approach networks. But the development of gray-box and white-box penetration testing approaches was prompted by time restraints and the need to find and fix vulnerabilities inside the perimeter as well.
