Abstract: To study the problem of network threat assessment, a new method based on attribute recognition theory was proposed. This method extracted indicators of network attacking events in a period and modeled with entropy value to determine weights. Threat degree was quantified after the assessment and classification of attacking events in the network. The example's results indicate that this method is simple, practical and able to assess network threats effectively.
