Weak Tranquility Property

Definitions

Definition 1

A secure level of the tranquility property where security clearance levels and security classification levels are first initialized and then may be modified following a procedure that assures the legitimacy / authority of the person ordering the change, and the security of the system throughout the transition to the new state.

This tranquility level imposes less constraints on the system than strong tranquility but more constraints than no tranquility.

A system with weak tranquility is tranquil and complies with the tranquility principle.

Note

If not specified otherwise, the tranquility property refers to both security clearance levels and security classification levels. But the concept may be applied to only security clearance levels or security classification levels, in which case it is recommended to express it explicitly.
