Actual exam question for Arcitura Education's S90.18 exam
Question #: 87

[All S90.18 Questions]

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?

Option B all the way! Unless you're working for the NSA, there's no need to turn this into a James Bond movie. Transport-layer encryption is the way to go, folks.

Option B is the clear winner here. Why make things more complex than they need to be? Keep it simple and secure with transport-layer encryption.

Hmm, I'm not sure. Option C with SAML tokens might be a bit overkill, but it could provide more robust authentication. Tough call, but I'd probably still go with Option B.

Option B sounds good. It encrypts the communication channel between Service A and Service B.

I agree with Gregoria. Option B is the way to go. No need to over-complicate things when a simple transport-layer encryption can do the job.

But wouldn't encrypting the communication channel be more efficient?

Option B seems like the best choice here. Encrypting the communication channel at the transport layer is a lightweight and efficient way to meet the security requirements without the overhead of XML encryption or SAML tokens.

An authentication broker could add an extra layer of security between the services.
