ISO/IEC 15408:
security requirement, which contributes to fulfil the target of evaluation (TOE) security problem definition (SPD) (as defined in a specific security target (ST) or in a protection profile (PP)
Note. A security functional requirement can be addressed directly as in the direct rationale model, or indirectly, through the security objectives for the TOE, as in the general model.
