A penetration testing firm is hired to assess a client's web application that integrates with a third-party payment processor's API. The client wants to include the payment processor's API in the test scope. Which action should the tester take FIRST?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

Begin testing the API because it is part of the client's environment

This is incorrect because testing a third-party service without authorization is illegal and could breach contracts.

B

Best answer

Request written permission from the payment processor

This is the correct first step. The tester must obtain explicit permission from the third party to ensure legal and ethical testing.

C

Distractor review

Only test the client's internal systems, excluding the API

This ignores the client's requirement to test the API; if permission can be obtained, it should be included.

D

Distractor review

Use the payment processor's sandbox environment without notifying them

Even sandbox environments are subject to terms of use; unauthorized testing is still not allowed.

Common exam trap

Common exam trap: authentication is not authorization

Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.

Technical deep dive

How to think about this question

This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.

KKey Concepts to Remember

  • Authentication checks who the user is.
  • Authorization controls what the user is allowed to do after login.
  • Privilege levels affect access to EXEC and configuration commands.
  • AAA, TACACS+ and RADIUS can separate login success from command access.

TExam Day Tips

  • Do not assume successful login means full administrative access.
  • Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
  • Separate login problems from permission problems before choosing the answer.
