Methodology for Black Box Penetration Testing

To stop a malicious code, one must think like an attacker, which is exactly what penetration testing (pen testing) is about. Based on the conditions, a company can use a variety of pen testing techniques.


For example, black box penetration testing involves no prior knowledge of the network or application and is performed against a variety of real-world hacking situations.


We’ll go through the basics of black box penetration testing. We’ll look at the testing’s concept, instance, strategy, methods, resources, benefits, and drawbacks. Many of our customers request pen testing services to reveal security flaws in their networks, as well as how these flaws were abused, and the procedures required to remediate them.



What is Black Box Penetration Testing, and how does it work?



Black box pen testing is used to assess a system’s vulnerability to external elements that could be exploited by an external attacker to compromise the network’s safety. A black box test examines the software’s inputs as well as the results it produces.

The tester does not have access to the source code, hardware implementation, or understanding of the computer’s internal parts.

The test cases are written in accordance with the needs of the application. Clients’ connections or interface requirements that allow several systems and procedures to access to the application are the only ways to break into the program.

Because the pen tester has little information, black-box testing takes less time than other methods of penetration testing, such as white box testing. The tester merely looks at the computer’s graphical user interface and does not need to go into the code to find process flaws. Also, because the codes haven’t been fully distributed, there are less operational requirements.

Why should you conduct a black box test?

1. Black box testing enables you to rapidly spot problems in specified requirements.

  1. It allows for impartial testing because the inventor and tester are both separate.
  2. Testing is done “from the user’s perspective.”
  3. Black box testing not only detects security flaws in the system, but it also aids in the detection of hidden GUI faults.
  4. Black box testing replicates the behaviour of a user who is unaware of the project’s inner structure.



Types of Tests


The “black box” method is used for the following sorts of testing:


Functional tests are designed to examine each functionality of a software package by giving actual inputs and comparing the result to the required functionality.

Regression: Its goal is to show that a previously working application can continue run properly after specific elements have been revised. Regression testing ensures that no changes have been made.

Non-functional: The major purpose of non-functional testing is to verify a specification that outlines the criteria that will be used to measure overall system performance. Non-functional needs like as accessibility, appearance and feel, productivity, and safety, are combined in these.



Advantages of Penetration Testing in a Black Box


Penetration testing in a black-box environment is insufficient for finding all security flaws in a platform. When combined with source review process and other testing, it gives a comprehensive image of the systems and network’s safety condition.



A black-box pen test can help you in the following ways:


  • It simulates a hacker attacking your application. It discovers the exposed weaknesses in your systems and applications in the literal sense of the word.


  • It can help you spot development and config errors because it tests the app in real-time.


  • It recognizes erroneous commercial builds (old or missing files, for example).


  • It employs social engineering approaches to identify security problems involving humans.


  • It is capable of identifying security holes that arise from interactions with the surrounding system. 


  • It can spot problems like input/output validity flaws, data leak in error codes, and so on.


  • A black box penetration test can be less expensive than other methods of pen testing, such as grey box and white box.


Software security is a continuous activity. You create, test, protect, and repeat the process. An app can be tested in a variety of ways. One of the most prevalent types of testing is penetration testing.

Black-box penetration testing allows you to check for implementation, authentication, and other issues in your known online. Black-box penetration testing does not show all that is wrong with an application’s security by itself. The efficiency of a black-box penetration test is increased when it is combined with other testing, such as open-source inspection.


The Labsard Methodology


The following is a general explanation of some of the areas that will be evaluated:

Labsard begins black-box penetration testing with approaches based on the Penetration Testing Execution Standard (PTES), which can be summed up as follows:

Labsard searches for as much data on the objectives as feasible during the first stage of a penetration test. This includes identifying used devices, services, and apps, as well as locating valid user profiles and doing other tasks.


Vulnerability Assessment: After all services and applications have been positively identified, Labsard analyses any malfunctions, design flaws, or other vulnerabilities discovered.

Labsard tries to attack any flaws or weaknesses revealed in found resources that are part of the testing scope during this phase. Labsard will attempt to actively attack any discovered weaknesses or flaws in the servers or web implementation in order to breach it from a black box viewpoint. 


Post-exploitation: After acquiring access to a hacked device/application, we seek to take complete control of it, decide its utility for future attacks, and, if necessary, make lateral displacement farther into a system.


Reporting: We give a summary of all threat vectors found, as well as their seriousness (based on intricacy, frequency, user involvement, and other factors) and suggested remedial methods.


Deliverables and Reporting:


Reports on Pen Testing — After any testing, a full detailed report must be made public. The report will detail the testing methodologies utilized, the results, any solid evidence code for appear credible, and remediation procedures and recommendations.


Labsard will record the testing procedures utilized, preserve all obtained data, and generate proof-of-concept attacks for repeated testing in the case that an attack, hack, or penetration is successful.


Targeted Remediation Retest — Following penetration testing, one or more weak points may need to be reconfigured, patched, or replaced. When these regions are available and repair is completed, Labsard will retest them. If performed within 90 days after the initial test, re-testing is included price.
