Why is Black Box Testing Necessary for Software Security?

Let us first get to know what Black Box testing is and if it is an integral part of software security testing. Broadly speaking, it is defined as a type of software testing within which the internal structure/design/implementation of the object being tested is not entirely known to the tester. Also known by the term Behavioral Testing, the specialty and uniqueness of this type of software testing is that it can be virtually implemented on all kinds of software testing such as unit, integration, system, and acceptance.

Black Box penetration testing is primarily focused on software requirements & specifications, and is largely centered upon the inputs and outputs of the software system without paying much attention to the internal knowledge of the software program.

Black Box Testing can look closely at many levels of security as well as any impending server level threats. This method of testing gives a platform to security experts to think differently and initiate tests on every level based on their practical skills and knowledge.  The objective of this testing is to prevent risks that can act as a future threat from hackers, insiders or any possible rivals.

While you test software, it is necessary to undergo a proper process that should be unbiased, as the development process can be easily duplicated or misused by the tester if he gets all the required information. To prevent this kind of a scenario, you can simply delegate a task to a tester by providing them with the software, with no further help on the procedure of development. This will make it a natural and unbiased testing.

Black Box Testing deploys this concept, wherein the tester has no knowledge about the underlying code of the software application.In this, the tester can’t determine the actual procedure of development and the steps that went into the development of the software.This prevents the tester from making any presumptions regarding the operation of elements, eventually making him analyze each function as it is.

Advantages of Black Box Penetration Testing Procedure

  • Provides you with real attack conditions
  • Gives you various potential threats with proper documentation
  • Promotes non-disclosure of project source codes

Step by step procedure of Black Box Testing

  1. Scrutinize all the requirements and specifications of the system.
  2. Select valid inputs (positive test scenario) to ensure whether SUT (System Under Test) processes them properly. Along with this, some invalid inputs (negative test scenario) should also be included. This is done in order to verify whether the SUT is able to identify them precisely or not.
  3. Decide predictable outputs for all those inputs.
  4. Craft test cases with the assistance of some chosen inputs and carry out test cases.
