1. A communication requirement generation system comprising:
a storage unit configured to store definition information for calculating a logical distance between a first component that is connected to a network and a second component which is a communication partner of the first component;
a determining unit configured to calculate, for each of a plurality of communication requirements related to the first component, the logical distance between the first component and the second component based on the definition information stored in the storage unit, and determine, based on the logical distance, whether each of the communication requirements is a communication requirement that requires confirmation of an operator of the network;
a deciding unit configured to decide a security level indicating security strength of the first component;
an input unit configured to input information used for determining the security level of the first component as information of the first component; wherein
the storage unit stores security level condition information indicating a condition for determining the security level of the first component,
the deciding unit decides the security level of the first component based on the information of the first component input from the input unit and the security level condition information stored in the storage unit, and
the determining unit determines whether each of the plurality of communication requirements related to the first component is the communication requirement that requires confirmation of the operator of the network based on the security level of the first component; and
an output unit configured to output the communication requirement determined by the determining unit when the communication requirement is the communication requirement that requires confirmation of the operator of the network.
