Abstract

The embodiment of the present application discloses a network risk detection method, device, equipment and medium based on object characteristics, belonging to the field of computer technology. The method includes: receiving an access request carrying object information, performing feature extraction on the object information to obtain a feature vector, detecting the feature vector through a detection model to obtain a detection result, and determining the object as Risk objects realize the automatic detection of network risks without manual analysis, which can save manpower and time, and improve the accuracy and efficiency of network risk detection. Moreover, through the interpretation model corresponding to the detection model, the eigenvector is processed to obtain an interpretation vector. According to the interpretation vector, it can be known which eigenvalues ​​in the eigenvector cause the object corresponding to the eigenvector to be detected as a risk object, so that the detection result It is easy to understand, and the interpretability of the detection model is realized through the interpretation model corresponding to the detection model.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a network risk detection method, device, device and medium based on object characteristics. Background technique [0002] With the rapid development of computer technology, network security issues have become increasingly prominent. There are risk objects such as suspicious devices or suspicious IP (Internet Protocol, Internet Protocol) addresses in the network. These risk objects often perform malicious behaviors, such as risk objects. Website attacks, malicious brushing of tickets, malicious grabbing of tickets, malicious visits, fraudulent acts on the website, etc. Therefore, it is necessary to detect risky objects on the network in order to protect network security. [0003] In related technologies, when an access request is received, object information corresponding to the object initiating the access request is obtained, and the object inf...
