Arcitura Education S90.18 Exam - Topic 1 Question 87 Discussion

Service A is owned by Organization A . Service A sends a message containing confidential data to Service B, which is owned by Organization B . Service B sends the message to Service C, which is also owned by Organization B . Organization A trusts Organization B, which means there is no requirement to protect messages from intermediaries and after a message is received by Service B (and as long as the message remains within the boundary of Organization B), there is no requirement to keep the message data confidential. Which of the following approaches will fulfill these security requirements with the least amount of performance degradation?
A) Messages exchanged between Service A and Service B are encrypted using XML-Encryption.
B) The communication channel between Service A and Service B is encrypted using a transport-layer security technology.
C) SAML security tokens are used so that Service B can authenticate Service A.
D) An authentication broker is introduced between Service A and Service B.

SAML tokens seem more about authentication than confidentiality, so I'm not sure if that would meet the requirements here.

This is a tricky one. I'm not sure if the SAML tokens or authentication broker are really necessary given the trust relationship. I'll need to carefully weigh the pros and cons of each approach.

I'm leaning towards option A since it provides message-level encryption, which seems more secure than just encrypting the transport channel. But I'll need to double-check the performance implications.

Okay, I think I've got it. The key is that there's no need to protect the message once it's within Organization B, so I'd go with option B to minimize performance impact.
