Abstract

The invention relates to a website risk index calculation method based on a massive Web log, comprising a collection unit supporting the massive Web log, a safety information analysis unit and a website risk assessment unit arranged on a Web server; the collection unit, the analysis unit and the evaluation unit are sequentially connected. The collecting unit monitors the log file in real time, extracts the Web log generated in real time according to a certain time interval, and pretreats the generated fields. The invention is based on massive Web log analysis, can catch Web attack events in real time, combines the CVSS value with the vulnerability of the website and the harm degree of the attack, carries out the website risk assessment, and ensures the accuracy, real-time and predictability of the assessment index.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a website risk index calculation system and method based on massive web logs. Background technique [0002] With the rapid development of the Internet, the complexity and importance of network security have become increasingly prominent. With the continuous occurrence of network attacks, the issue of network security has attracted more and more attention. Website risk assessment technology is based on the current environment of the website, analyzes the vulnerability of the current website and the threats it faces, and provides accurate and objective risk data, which is of great significance for the construction of website security and the improvement of the defense system. As an important part of network security, Web logs extract and analyze real-time attack events and provide important information for computer forensics. CVSS (Common Vulnerability Scoring System) pr...
