I remember studying access control models, and I feel like it could also be "Biba model," which focuses on integrity.

I think the answer might be "Bell-LaPadula model," but I'm not entirely sure if that's the right one for data integrity.

No problem, I've got a good strategy for this. I'll start by listing out the key elements of a formal state transition system, then match that to the description provided in the question.

Wait, I'm a bit confused. Is this asking about a specific security model or a general description of access control policies? I'll need to re-read the question carefully.

Okay, I've got this. The answer is definitely "Bell-LaPadula model". It's a classic access control framework for ensuring data integrity.

Hmm, this seems like a tricky one. I'll need to think carefully about the key security concepts and how they relate to the question.
