A Risk Assessment Method for the Internet Boundary Security

In order to assess the security risks of the Internet boundary in real time, this paper summarizes the characteristics and the security requirements of the network boundary, and proposes a risk assessment method for Internet boundary security, which combines the security strategies that has been activated, the attack complexity and the attack threat degree, at the same time, the triangle module fusion operator is introduced to calculate the security risk of the network boundary. This method evaluates the remaining risk of the network boundary quickly and efficiently by detecting the effectiveness of the security equipment deployed in Internet boundary, it has a certain practical value.
