A risk situation evaluation model for network security is proposed based on analyzing security threat status. This method first perceived and identified the characteristics of critical risk factors, such as asset, vulnerability and threat, from multi-security-sensors. Then a quantitative evaluation algorithm was presented to estimate current threats and potential threats. By analyzing their threat degree, the real-time status and dynamic evolvement trend of security risk was revealed. Sequentially, the security administrator can comprehend the situation about both the single entity and the overall network then timely and effectively make security decisions. Finally this method was illustrated and validated in an emulated network environment.
