The invention discloses a
data security monitoring method based on risk early warning, particularly relates to the field of
data security, and comprises the steps of multi-
source data acquisition,
index system calculation, comprehensive
threat scoring, dynamic risk judgment and
response strategy execution. According to the method, a three-dimensional
monitoring system is constructed through a multi-source heterogeneous data fusion analysis framework, a traditional single-dimensional monitoring blind area is eliminated, a quantitative
score is generated by combining a three-layer nonlinear evaluation model with double-track baseline analysis and dynamic aggregation of basic parameters, double
verification of historical rules and real-time fluctuation is achieved, the
threat judgment accuracy is remarkably improved, and the
threat judgment efficiency is improved. An intelligent
mapping system of risk levels and disposal strategies is established, differential response plans are matched through three-level risk division, and a closed-loop feedback channel is synchronously constructed, so that high-risk events are quickly isolated for evidence obtaining, low-risk abnormities are accurately controlled, and a complete iterative loop of assessment disposal optimization is formed. And the active
adaptive capacity and the response timeliness of the security defense
system are enhanced.
