Research on Computer Big Data Technology in Generative Countermeasures Network Security Protection

In order to make up for the shortcomings of the current network security situation assessment system, this article proposes a network security situation quantitative assessment algorithm based on the offensive and defensive confrontation environment. Based on in-depth analysis of various factors affecting the security situation, this method combines traditional risk assessment with environmental factors such as network protection status and asset security characteristics, extracts multiple quantitative indicators, and conducts a quantitative assessment of the security situation according to the attack category. The case analysis shows that the method is in line with the actual confrontation network environment, and can accurately predict the attack time and reasonably quantify the attack threat.
