Embodiment Construction
[0060] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0061] The invention mainly solves how to identify potential operating users based on multi-source heterogeneous host audit logs, and provides instructive abnormal analysis for suspicious situations of identification errors.
[0062] Such as figure 1 As shown, the system of the present invention includes a data processing module, a joint embedding module, and an evaluation and analysis module. The data processing module analyzes and processes the original multi-source heterogeneous host audit log data, retains predefined key fields, and uses standardized historical log data to build a heterogeneous information network; the joint embedding module uses two kinds of heterogeneous information The network embedding algorithm learns the operation mode of a single host and captures the global association of the network respectively. The two heterogeneous i...
