Abstract: Risk assessment is an effective approach to evaluate security state of information systems. A model of information security risk assessment system based on immune network both with a quantitative evaluation theory are presented. This model can reflect the relationship of the evaluation factors. It has the features of self-learning, self-update and real-time detecting. Experiment shows the model is effective to assess the risk of information systems.

Key words: risk assessment, immune network, risk quantification
