Exam 200-901 topic 1 question 102 discussion

It is B Since the application receives a webhook over HTTPS without a secret, there is a risk that the credentials in the webhook information could be transmitted over the network without encryption. Using HTTPS is a secure way to transmit data, but without a secret or proper authentication, there is a risk of unauthorized access. Enabling transport layer encryption (such as HTTPS) and ensuring proper authentication mechanisms for webhooks are essential to prevent the exposure of sensitive information during transmission.

From my point of view C is the correct answer because B says something about during transport which is HTTPS and which is encprypted -> So no security issue because you cannot decript it. And when using webhooks debug, an atacker can exploit this vulnerability and obtain the credentials. So the problem is that this debug should not be present in a production app constructed in this way.

This is tricky. It seems that all aspects of security are valid until debugging happens. When the webhook is sent, even though the creds are in plain text in the data payload, the transmission is encrypted with HTTPS. Then those creds are stored in with a secure hash. Then they're accessed with a vault service. The only insecure part is the debugging. When the debugging happens, you can see the user/pass in the debugging logs. Technically, that makes B correct, as the logging is done after the HTTPS is decrypted, but it also makes C correct. However, the question asks what the issue is, not what the solution is. Answer C is a solution, not the issue, so I'm going with B.

B is the correct answer!

No A: Credentials to the database are accessed at runtime through the use of a vault service B is make sense because no secret, without secret is the key. No is posible complete some process of security C no make sense D Webhook usea hmac for guarantee integrity and source

Its saying that HTTPS is used during webbook which makes me think its not B and should be A

I think it should be B

I guess is C

Its B for me

The credentials are received on clear text so B is incorrect. A makes sense as this is a best practice
