Simple integrity property :-

This property states that a subject at one level of integrity is not permitted to read an object of lower integrity.

Star * integrity property: -

This property states that an object at one level of integrity is not permitted to write to an object of higher integrity.

Invocation property :-

This property prohibits a subject at one level of integrity from invoking a subject at a higher level of integrity.
