The different types of pentests are classified into black box, white box or gray box. But how can this classification help in deciding on the right pentest?
Certain results are given with the type of pentest selected. Depending on which scenario you choose the direction and the result of the pentest are already narrowed down. Other factors that limit the choice of the pentest are the economic benefits (effort, costs) and the realism of the scenarios. The aim should be to optimize both.
Solutions require priorities; the pentest alone is not enough
If the pentest has been carried out with the objective and the correct scenarios by the commissioned pentesters, a list of weak points is obtained. However, this mere list does not solve a single problem, and it is still a long way from providing advice. In order to be able to react well to weak points in the company's IT, these must first be prioritized, because of course not all problems can be resolved at once. For this purpose, the risks that are frequent and have a major impact should be prioritized (e.g., with the help of the Eisenhower matrix). A well-sized pentest can for the most part provide this prioritization. The goal should be to fix the most realistic, costly, and business damaging scenarios first. So you have to think about which areas in the company are vulnerable, which of them are particularly important and become aware of the serious dangers and risks you are exposed to. For this it is essential to know your own requirements.
The most important thing, however, is to act to the results of the pentest and take action. If I remain passive after the pentest and do not change anything in the company in order to ensure more IT security and to close my own security gaps, then even the most comprehensive and cost-intensive pentest is ineffective.
