    Handling

    * Allocation of User Requirements

    In this activity, the total User Requirements and Marginal Conditions for the System have to be allocated to the elements of the technical architecture.

    This allocation of requirements is the basis for the requirements analyses and design steps taking place on the lower levels.

    It is necessary to observe that the allocation of requirements and Marginal Conditions to the elements of the technical architecture must fulfill the following criteria:

    * Allocation of IT Security Requirements to the IT Security Measures

    With the allocation of the IT security requirements to the IT security measures it must be proven that each IT security requirement is covered by at least one IT security measure, and if the specified IT security objective can be reached with the selected security measures.

    Notes:

    (1) In case a requirements controlling is to be realized on the basis of an actual architecture proposal.

    (2) Method ER is to be applied for Information Systems and only if modifications of the E/R models become necessary.
