inference vs aggregation - What is the difference?

[CCCure Support]

Good day Hasnain,

This is a great question.   I have included my CISSP mailing list in my response so they benefit from the answer as well.

AGGREGATION

Aggregation is an issue when you accumulate information of the same security clearance.   The sum of the information will be a higher level than each of the part.   For example:  While I was working for the Department of Defense, a single annual performance report was Confidential only.   However, if I had dozens of performance report together it had to be treated as Secret.   The sum would be higher than each of the part.  

INFERENCE

Inference is when you do multiple queries and you then have the ability to infer new information that normally you could not access directly.   You infer new things from the data set you have consulted. 

Best regards

Clement

Hi Clement , 

I am doing your quizzes for a while now , as I m 5 days away from my exam . 

Just a question , regarding inference and aggregation as I can't make up my mind to understand the difference between the 2 .

I feel both are the same thing , Can you please help me to understand the trick of what to select as the questions are so similar and one has inference as the answer and the other has  aggregation as the answer.

IF you can help that would be good .

thanks
