A Dependency matrix
3.7 Insiders’ knowledge bases
Knowledge Base (KB) which defines the data elements from the inside may read. In fact, it is the profile of the inside up to the data elements. The building knowledge based on different levels of the granules of cloud data center. In light of the preceding paragraph, and concluded the following:
If the insider gets read access to the knowledge that belongs to the cluster, and she / he can obtain information about the other entire knowledge unit in this group according to dependencies.
3.8 Insiders’ Knowledge know-how the numerous varieties of dependencies in multi stage cloud datacenter enable us to discover the information that insider can get. As we discussed previously , insider may use dependencies to gather authorized expertise , which might be categorized into three kinds : inferred Knowledge, computed Knowledge, and aggregated Knowledge.
3.8.1 Inferred Knowledge
The kind of knowledge that insider can get using inference is called inference Knowledge that is described as comply with : Definition (Inferred Knowledge). Given a dependency courting A → B in Cloud data base system D such that a and B are objects in D, then the information that an insider deduces about B via getting access to A, is referred to as inferred
