For example an accounting firm need to be sure that the company send a check for $1000.00 and not for $100000, oh man I would like to receive that money, LOL It is a big different. Now this is the idea for the Biba model.
Again, this info I got it from Shon Harris book, this is a good book for CISPP (if you really wants to know the details).
This is the cream for the Biba model:
- *-integrity axiom: A subject "cannot write up"
- Simple integrity axiom: A subject cannot "read down"
- Invocation property: A subject cannot request service (invoke) of higher integrity.
Lets say another example: What happen if I would begin to write anything I think about Biba model, would be the information corrected, who knows, but in this case I am taking details from Shon Harris book then the integrity of the information is right, remember that.
