Thus, a clearer ranking of event records for the confidence metrics can be achieved.
In an embodiment of the present application, the events and the measurement results in each event subclass may also be sorted according to a preset credibility measurement attribute of a third priority. The trusted metric attribute of the third priority may be, for example, a trusted metric trigger time, so that the time may be arranged in sequence, or arranged in reverse order.

Taking fig. 2 as an example, it is an example of the output trusted report. In this example, the confidence measure of the event is triggered to a second priority with the security level as the first priority. In the credibility measurement log, events are divided into four major categories of events, namely "high security", "medium security", "low security" and "normal security". In each major class, three minor classes, "event type one", "event type two", and "event type three" are recorded from high to low in terms of frequency. The trusted metric trigger time is the third-priority trusted metric attribute in the records of each subclass, and may be arranged in ascending or descending order of the trusted metric trigger times of the events.
