Final answer:
Correct answer is D) .The Biba security architecture model is based on the premise that higher levels of integrity are more worthy of trust than lower ones. It focuses on preventing information flow from lower to higher integrity levels.
Step-by-step explanation:
The security architecture model that is based on the premise that higher levels of integrity are more worthy of trust than lower ones is Biba.
The Biba model focuses on integrity and takes a cautious approach towards information flow. It prevents information from flowing from lower integrity levels to higher ones, ensuring that higher levels are not compromised by lower levels. This model is often used in systems where data integrity is critical.
For example, in a multi-level security system where classified information needs to be protected, the Biba model ensures that information at a lower classification level cannot be modified by a user with a higher classification level.
