The target data may be service data, and the service data may include: user data (which refers to basic information of a user), behavior data (which refers to data recording what the user has done, mainly including what behaviors the user has done, time when the behaviors occur, and the like), commodity data (which includes commodity names, commodity categories, commodity comments, inventory, and the like), and activity data (activity information of a platform).
The embodiment of the application provides a detection method based on graph-like calculation, various risk types are integrated together in a topological graph mode, each node of the topological graph indicates one risk type, and a plurality of target risk detection paths are organized through the nodes and the connection among the nodes. And multiple risk detection nodes along the target risk detection path can realize multiple risk detection on the target data.
The method and the device have the advantages that the value of various risk detection types can be fully exerted, the detection mode can be adjusted by adjusting the topological relation of the graph, and flexibility is achieved.
The advantages of the technical idea include: (1) The length of the path represents the depth of analysis, the longer the length of the path is, the more risk detection nodes the path passes through are shown to be, the higher the reliability of the obtained detection result is, the risk can be accurately positioned by utilizing the result, and the black birth team is traced and accurately struck.
(2) And the out-degree of the risk detection node represents the richness of the analysis cross validation, and the same batch of data is subjected to rich labels, so that the cross validation is carried out. For example, for the same batch of data, the results analyzed by the risk detection node a, the risk detection node B, and the risk detection node C are obtained and compared, and the detection effects of different risk detection nodes are verified according to the comparison results. Generally, the more data intersections of risks of different nodes, the more accurate the risk detection effect is.
In one embodiment, referring to fig. 2, the method further comprises:
(1) Determining risk types and incidence relations among the risk types;
(2) And taking the risk types as risk detection nodes, and constructing edges based on the incidence relation among the risk types to obtain a risk detection topological graph.
The above embodiments provide a method for establishing a risk detection topological graph. For example, a risk type a, a risk type B, a risk type C, and a risk type D are preset, for example, risk type a is associated with risk types B and C, and risk type B is associated with risk types C and D; then, the risk type a, the risk type B, the risk type C, and the risk type D may be used as risk detection nodes, and edges are constructed between the risk types a and B, the risk types a and C, the risk types B and C, and the risk types B and D, respectively, to obtain a risk detection topological graph.
Alternatively, the risk types in the topological graph and the association relationship between the risk types can be flexibly established by a user, and the method has flexibility.
In one embodiment, the risk detection topology is a directed topology, and the edges between the risk detection nodes are directed edges to indicate the flow direction of the risk detection.
For example, the risk detection node a → the risk detection node B indicates that the data detected by the risk detection node a is detected by the risk detection node B. The flow direction of wind direction detection can be indicated through the directed edges, so that the possibility of formulating the risk detection flow direction can be realized, and more possibilities are provided for a user to design a detection scheme.
In one embodiment, the step S103, based on the risk type corresponding to the target risk detection path, performing risk detection on the target data along the target risk detection path, and includes:
(1) Selecting a target risk attribute corresponding to the risk type in the target risk detection path from preset risk attributes, wherein the preset risk attributes are determined based on the attribute characteristics of the risk object after the risk object is identified from known risk data;
(2) Acquiring a target risk object corresponding to the target risk attribute;
(3) And detecting whether the target data has risk data matched with the target risk object or not until all the corresponding risk types in the target risk detection path are detected.
Wherein the risk object and the attribute feature may each be determined from one or more dimensional combinations. For example, a piece of data of a risk object (ip, cuid) on attribute features (past, requests) can be (202.118.231.56,12345678) - (88888,300), wherein the risk object includes two dimensions of ip and cuid, the attribute features include two dimensions of past and requests, 88888 represents an attribute value of past, and 300 represents an attribute value of requests.
Taking the risk object (ip, cuid) and the corresponding attribute features (past, requests) as an example, the process of acquiring the known risk data may be as follows: according to intelligence data collected by a plurality of intelligence sources, after an air risk object (202.118.231.56,12345678) is identified from the intelligence data, an attribute feature (88888,300) of the air risk object is determined, and known risk data (202.118.231.56,12345678) - (88888,300) are obtained according to the air risk object and the attribute feature of the air risk object. At this time, the preset risk attributes may include (granted, requests).
One specific example of the above step S103 may be as follows: for example, the target risk attribute of the risk type is (past, requests), and target risk objects corresponding to the target risk attribute (past, requests) such as (ip 1, cuid 1), (ip 2, cuid 2), (ip 3, cuid 3) may be selected from known risk data.
Taking the known risk data related to (ip 1, cuid 1), (ip 2, cuid 2), and (ip 3, cuid 3) as reference, the risk object (ip 1, cuid 1) also exists in the target data, and at this time, it can be determined that the data related to the risk object (ip 1, cuid 1) in the target data is risk data, and the risk type exists.
In one embodiment, the method further comprises:
and taking the risk data matched with the target risk object in the target data as known risk data so as to optimize the preset risk attribute and the risk object.
For example, in the above example, the risk data (ip 1, cuid 1) - (past 1, requests 1) are selected, and the preset risk attributes (past, requests) and the risk objects (ip, cuid) can be optimized by using the known data.
In one embodiment, further comprising:
(1) Acquiring the weight of the target risk type;
(2) Determining a risk value of risk data corresponding to a target risk type; the risk value is obtained based on the matching degree of the target risk object corresponding to the target risk type and the risk data;
(3) And obtaining the risk degree of the target data based on the weight of the target risk type and the risk value of the corresponding risk data.
For example, since the risk detection type a has a weight of a, the obtained risk value of the risk data is A1, the risk detection type B has a weight of B, and the obtained risk value of the risk data is B1, the obtained risk degree is (A1 × a + B1 × B).
In one embodiment, obtaining a risk detection result includes:
detecting that risk data matched with the target risk object exists in the target data;
taking risk data matched with the target risk object as a risk detection result; and/or the presence of a gas in the gas,
and taking the risk type corresponding to the target risk object as a target risk type, and taking the target risk type as a risk detection result.
And if the risk type corresponding to the risk existing in the target data is the target risk type. For example, risks corresponding to risk types of a node a, a node B, and a node C on a path all exist, the target risk type of the target data is considered to be a risk type corresponding to each of the node a, the node B, and the node C, or after risk detection of the node a, the node B, and the node C, risk data of a risk type corresponding to each of the node a, the node B, and the node C exist in the target data is obtained.
Optionally, in the detection of each risk detection node on the passing path, risk data with a risk corresponding to the risk detection node is determined from the target data, and a risk label of the risk detection node is marked on the risk data.
Correspondingly, the risk detection result of each path comprises risk data which are in accordance with all risk types on the path in the target data, and the risk data carry risk labels of all risk types on the path. The risk label can be used for further processing or analysis of the risk data, such as statistics of distribution of various risk labels of the target data.
The following is a specific example of an embodiment of the present application.
Based on the technical scheme provided by the application, a calculation process can be constructed, the input of the calculation process is business data, the output of the calculation process is business data with risk labels, statistical information of various risk labels comprises the attribute of each risk label and the proportion of each risk label data in the business data, and the calculation process comprises two main modules as shown in figure 2: a Risk Detection Graph module (RDG) and a fact maintenance module (GTM).
The RDG is mainly used for analyzing and calculating business data (mainly log data), and the input of the RDG is the log data and also needs fact data provided by a GTM (data to be saved) as support.
While GTM is a computing module built on a Threat Intelligence Data Warehouse (thread intelligent Data ware). In one aspect, the GTM builds fact Data (Ground Truth Data) from Data in the threat intelligence Data warehouse, as shown, the fact Data (including tag/statistics/allocation Data) required for the threat intelligence Data warehouse calculations are provided to the GTM for use by the RDG.
