Abstract

The present application discloses a big data-based security policy optimization processing method and device. The method includes: obtaining an upload log file uploaded by a user and a defense policy corresponding to the log file; when the number of log files corresponding to a predetermined defense rule reaches a threshold, inputting the log file and the defense rule as training data into a pre-configured The machine learning model is trained to obtain the training model corresponding to the prevention rule; the log files to be identified are respectively input into multiple training models, and the probability value corresponding to the log file and each training model is obtained; the combined prevention Policy hints to uploaders of scheduled log files. The present application solves the problems in the related art that the manual definition of defense strategies against network attacks is not precise enough and the prevention strategies are lack of training data for formulating defense strategies through machine learning training models. This reduces the dependence on people in the process of formulating prevention strategies.

Description

technical field [0001] The present application relates to the field of machine learning, in particular, to a big data-based security policy optimization processing method and device. Background technique [0002] In the existing technology, there are many kinds of network attacks. At present, the prevention of network attacks basically relies on manual formulation of strategies. This requires every network administrator to have rich experience, which is impossible to some extent. [0003] With the development of machine learning, many machine learning models have been open sourced. An important prerequisite for formulating a network attack prevention strategy through machine learning is the need for a large amount of training data. Network attacks and their corresponding prevention strategies are generally not easy to obtain as training data for individual administrators. Therefore, the machine learning model is easy to build, but the difficulty is how to obtain a large a...
