Explanation / Answer

Reiterating your question again - File access control relates largely to the secrecy dimension of security. What is the relationship between an access control matrix and the integrity of the objects to which access is being controlled?

To understand above, first we need to understand what is Biba Integrity Model.According to Biba model,users can only create at or below their own integrity level.Conversely, users can only view content at or above their own integrity level. This means that a user’s integrity cannot be tainted by reading bad information; a user cannot taint more reliable information by writing into it.Since this is an access control policy, it can be represented as an
access control matrix. Thus controlling how subjects can read and write objects can also enforce integrity. In essence, the access control matrix for integrity sets permissions to prevent unauthorized modification of objects.
