Definition
Trust is an assumption that an entity, system or process will behave as expected under defined conditions and within a defined scope.
Human Explanation
Every system relies on some degree of Trust. Greater Trust usually brings greater privileges or responsibility.
Why it Matters
Misplaced Trust may enable unauthorised access and increase the consequences of security incidents.
Conceptual Boundary
Trust should not be granted automatically. It should result from verification, controls and deliberately defined rules.
Practical Perspective
Modern security systems increasingly use limited or verified Trust instead of Trust by default.
