The correct answer is D. The results should reflect what attackers may be able to learn about the company. Black box penetration testing simulates a real-world attacker with no prior knowledge of the target, producing results that closely reflect what an actual threat actor could discover.

Question

Due to compliance regulations, a company requires a yearly penetration test. The Chief Information Security Officer (CISO) has asked that it be done under a black box methodology. Which of the following would be the advantage of conducting this kind of penetration test?

Options

  • AThe risk of unplanned server outages is reduced.
  • BUsing documentation provided to them, the pen-test organization can quickly determine
  • CThe results will show an in-depth view of the network and should help pin-point areas of
  • DThe results should reflect what attackers may be able to learn about the company.

Why each option

Black box penetration testing simulates a real-world attacker with no prior knowledge of the target, producing results that closely reflect what an actual threat actor could discover.

AThe risk of unplanned server outages is reduced.

Black box testing does not reduce the risk of server outages - without prior knowledge of the environment, testers may inadvertently cause disruptions that a white box test would avoid through coordination.

BUsing documentation provided to them, the pen-test organization can quickly determine

Providing documentation to testers describes a white box or gray box engagement; black box methodology explicitly withholds all documentation and internal knowledge from the testers.

CThe results will show an in-depth view of the network and should help pin-point areas of

An in-depth view of network architecture is characteristic of white box testing where full system knowledge is shared, not of black box testing which relies only on externally discoverable information.

DThe results should reflect what attackers may be able to learn about the company.Correct

In a black box test, testers begin with no insider information about the organization's systems, directly mimicking the perspective of an external adversary. This methodology means findings are based solely on publicly available information and discovered vulnerabilities, making the results an accurate representation of what a real attacker could learn and exploit against the company.
