Operational Logic Validation
Definition
Validation of variable state in the context of the control logic of the operational application.
How it works
Validates the type, value, and/or range of a variable taking into account the local operational logic and operational state.
For example, if a controller has a restricted range when in a specified state, this may crosscheck the value against the state in addition to a more general range validation.
Artifact Relationships
This defensive technique relates to specific digital artifacts.
