Can we just glue Service A, B, and C together and call it a day? No security issues if there's no separation, right? Just kidding, I'm going with D. Service Abstraction, the only way to keep our sanity.

I think Service Abstraction is the best choice here. It keeps things separate and secure.

But what about Service Loose Coupling? Wouldn't that also help with security?

Wow, talk about a headache. Sounds like a trust fall exercise gone wrong. I'll go with D. Service Abstraction, but I might need a nap after this one.

Hold up, did they say we can't access the design specs? That's like telling a mechanic to fix a car without letting them see the engine. Gotta be D. Service Abstraction, right?

I'm not sure, but I think it could also be D) Service Abstraction, as it hides the complexity of the underlying services.

I agree with Bernardine, because Service Autonomy allows each service to control its own security.

Hah, talk about a trust issue! If I can't see under the hood, how can I be sure those other services are secure? I'm going with B. Service Autonomy on this one.

I think the answer is D. Service Abstraction. We're not given access to the design specs for Services B and C, so we can't guarantee their security level. Abstraction is the way to go here.
