CISSP Exam - Question 454


A security architect is reviewing an implemented security framework. After the review, the security architect wants to enhance the security by implementing segregation of duties (SoD) to address protection against fraud. Which security model BEST protects the integrity of data?

Show Answer
Correct Answer: D

The Clark-Wilson model is designed to enforce integrity through control mechanisms that ensure data is modified only in specific, legitimate ways. It includes mechanisms for implementing segregation of duties (SoD), which ensures that no single individual can control the entire process, thereby reducing the risk of fraud. By enforcing well-formed transactions and integrity constraints, the Clark-Wilson model is particularly effective in protecting the integrity of data while also addressing separation of duties. Therefore, it is the best choice for the given scenario.

In the context of the question D. The Clark-Wilson model makes more sense. The Clark-Wilson model addresses both segregation of duties (SoD) and data integrity. It enforces well-formed transactions and integrity constraints to maintain data integrity and also includes a mechanism for ensuring that users cannot perform conflicting duties, thus supporting SoD. Implementing SoD to address protection against fraud while also protecting the integrity of data, the Clark-Wilson model is the best choice. However, if the question only had that last line "Which security model BEST protects the integrity of data?" without everything mentioned before that, the correct answer would have been B. The Biba Integrity model. I believe they even added the word integrity on B. instead of just Bibal model to entice to pick that answer instead of D.

Answer B) The Biba Integrity model This is one of those 3 sentence questions where the first two sentences are trying to throw you off. The question asked, "Which security model BEST protects the integrity of data" and not "which should be used to facilitate segregation of duties"...or "which model will fulfill the requirements above"....

Read the WHOLE question: Which security model BEST protects the integrity of data? It's not asking you which model is for separation of duties.
