Embodiment Construction
[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0045] The flow chart of the network security effectiveness evaluation method according to the present invention is as follows: figure 1 shown, including the following steps:
[0046] Step 1: Identify the elements of the cybersecurity effectiveness assessment, and the factors that measure how each element of the assessment changes. Use network probes, perfmon performance counters, etc. to obtain the values of various factors before and after the attack, and preprocess the collected raw data to eliminate redundancy.
[0047] The network security effectiveness evaluation elements are recorded as: {network damage effect, asset damage effect, business damage effect, attack intensity, system protection capability}, of which:
[0048] The evaluation of network damage effect is to evaluate the degree of performance change of the network after being ...

The invention belongs to the technical field of the information security, and discloses a network security performance evaluation method. First, elements of the network security performance evaluation are identified, and each factor of evaluation element changes is measured; second, a network probe, a Perfmon performance counter, and the like are used to acquire a value of the each factor of the evaluation elements before and after an attack, and to pre-treat acquired original data; and finally, an evaluation value of each evaluation element is calculated, and the network security performance evaluation value is calculated. Based on the attack effect and the protection capability of the system, the network security performance evaluation method can measure the network security performance, discloses an attack and defense relationship matrix which describes interaction and offset between the attack and the defense, and overcomes the limitation that only the network attack effect is equivalent to the network security performance; and as for network attack effect and the protection capability of and the system, the measurable measurement factor is disclosed, so that the accuracy of the evaluation result is ensured.
Description
technical field [0001] The invention belongs to the technical field of information security, and relates to a network security effectiveness evaluation method. Background technique [0002] With the rapid development of network technology, the importance of the network has become increasingly apparent, but the security situation of the network is not optimistic. While enjoying the convenience brought by the network, people also pay more attention to how to protect the network system from attacks, and how to protect the network from attacks. System impact will be minimized. [0003] Network security effectiveness evaluation is to evaluate the effectiveness value of network security by analyzing the defense capability of the system, the degree of change in performance, availability, and security after the system is attacked, and the results of the offsetting of attacks and defenses in a complex network confrontation environment. . [0004] At present, there are two main type...
