Step S31, determining the information communication network where each hotspot sharing request is located from the obtained first hotspot sharing request queue; and grouping the information communication networks according to the information authority security level of the request object among the hotspot sharing requests in different information communication networks to obtain at least one information communication network set.

For example, the first hotspot sharing request queue is used to record hotspot sharing requests collected at different time intervals, and the hotspot sharing requests may be initiated to different terminals by different terminals, or may be initiated to the same terminal by different terminals. The request object may be understood as a terminal that initiates a hotspot sharing request. The information authority security level is used for describing the interaction security of the request object. The information authority security level of the request object of the hotspot sharing request in any two information communication networks in the same information communication network set is greater than or equal to the set level, and the set level is adjusted according to the actual situation, which is not limited herein.

Step S32, for each information communication network set, determining, based on each information communication network in the information communication network set, an information security evaluation feature corresponding to the information communication network set from the first hotspot sharing request queue.

For example, the information security evaluation feature at least includes network security index data of each information communication network in the information communication network set, and the information security evaluation feature is used for determining an access intrusion detection result corresponding to a hotspot sharing request in each information communication network in the information communication network set.

For example, the access intrusion detection result is used to represent a pre-detection result of an illegal access behavior of the hotspot sharing request to the current hotspot sharing terminal. And the identification result is used for representing whether the target terminal is a safe terminal.

It can be understood that, by performing the above steps S31-S33, the information communication network where each hotspot sharing request is located is first determined from the first hotspot sharing request queue and the information communication networks are grouped according to the information authority security level of the request object between the hotspot sharing requests in each different information communication network to obtain at least one information communication network set, secondly, determining information security evaluation characteristics corresponding to each information communication network set from a first hot spot sharing request queue based on each information communication network in each information communication network set, and finally determining access intrusion detection results corresponding to the hot spot sharing requests in each information communication network set based on the information security evaluation characteristics, and according to the identification result obtained by identifying the access intrusion detection result, the target terminal initiating the corresponding hotspot sharing request is accessed into the hotspot network corresponding to the current hotspot sharing terminal.

By the design, before the target terminal is accessed to the hotspot network corresponding to the current hotspot sharing terminal, the access intrusion detection result of the target terminal is identified, so that the information security relative to the current hotspot sharing terminal is ensured. Therefore, the target terminal passes the access verification before using the hotspot network corresponding to the current hotspot sharing terminal. The access intrusion detection result is determined based on the information security evaluation characteristics, and the access intrusion detection result can be respectively identified aiming at different information communication networks where different hotspot sharing requests are located, so that the access verification can be accurately and reliably realized. In addition, because the access verification is performed on the side of the big data cloud platform, a corresponding verification program does not need to be deployed in the current hotspot sharing terminal, and the running speed of the current hotspot sharing terminal can be prevented from being seriously slowed down.

In some embodiments, for step S31, the information authority security level of the request object between the hotspot sharing requests in different information communication networks is determined through the following steps a to c.

Step a, extracting network parameter distribution corresponding to each information communication network from the first hotspot sharing request queue.

And b, respectively inputting the network parameter distribution corresponding to each information communication network into a preset network parameter identification thread to obtain the request description information of the hotspot sharing request in each information communication network.

And c, determining the information authority security level of the request object corresponding to the hot spot sharing request in each information communication network based on the request description information of each hot spot sharing request.

Therefore, based on the content described in the steps a to c, the information authority security level of the request object corresponding to the hotspot sharing request in each information communication network can be determined in real time, and the delay of the information authority security level is avoided.

On the basis of the above, the determining, by step c, the information authority security level of the request object corresponding to the hotspot sharing request in each information communication network based on the request description information of each hotspot sharing request may further include implementing the content described in steps c1 to c4 below.

Step c2, when determining that the request description information is the legal information, determining a first request permission list corresponding to the request description information, and when determining that the request description information is the illegal information, determining a second request permission list corresponding to the request description information; and performing list time sequence correction on the first request permission list or the second request permission list to obtain a third request permission list.

Step c3, acquiring N list element combinations of the third request permission list and a permission event set corresponding to each list element combination, where each list element combination includes M different list information transmission paths, and N and M are positive integers greater than or equal to 1; determining the authority event transmission track corresponding to the list unit combination in the authority event set corresponding to the list unit combination; adopting the authority event transmission tracks corresponding to the list unit combination to carry out track trend identification to obtain path iteration data of each list information transmission path in the list unit combination; carrying out transmission track characteristic iteration on the authority event transmission track corresponding to the list unit combination based on the path iteration data of each list information transmission path in the N types of list unit combinations to obtain the authority event iteration track corresponding to the list unit combination; adding the authority event iteration track corresponding to the list unit combination into the authority event set corresponding to the list unit combination; and returning and executing the steps to determine the authority event transmission tracks corresponding to the list unit combinations in the authority event sets corresponding to the list unit combinations until the current fitting coefficients between the authority event transmission tracks corresponding to the N kinds of list unit combinations are larger than the target fitting coefficients.

Step c4, when the current fitting coefficient between the authority event transmission tracks corresponding to the N kinds of list unit combinations is larger than the target fitting coefficient, fitting the authority event transmission tracks corresponding to the N kinds of list unit combinations to obtain target transmission tracks; extracting a first track node with an information authority identifier and a second track node with an information security identifier in the target transmission track; respectively determining a first relative position weight of each first track node and a second relative position weight of each second track node; and calculating the weighted sum of the first relative position weight and the second relative position weight, and determining the information authority security level of the request object corresponding to each group of request description information according to the weighted sum result.

It can be understood that, by executing the contents described in the above steps c 1-c 4, different request type attributes of each set of request description information can be analyzed, so as to determine a request permission list in the case that the request description information is legal information and abnormal information, and further determine a target delivery track of the request description information, so that the information permission security level can be accurately determined in real time according to the weighted sum of the relative position weights of different track nodes corresponding to the target delivery track.

Therefore, when the contents described in the above steps S321 to S322 are executed, the network area description data can be determined for the information communication network, so that the information security evaluation feature can be accurately and completely determined according to the corresponding data authority update track, and a data basis is provided for subsequent access intrusion detection.

Further, the determining of the information security evaluation feature according to the data authority update trajectory of the network area description data described in step S322 further includes the following contents described in steps S3221 to S3223.

Step S3221, a plurality of continuous track sections of the data authority updating track are obtained, where one track section includes a dynamic updating track and a dynamic correcting track under one authority evaluation index.

Step S3222, based on the parameter mapping value and the authority description value recorded in the track section by the node parameter change of the data authority updating track, obtaining the node change track recorded by the node parameter change; performing first superposition on the node change track recorded by the node parameter change and a set change track in a preset track database to generate a first superposed node change track; and sampling to obtain an evaluation index change record from a node identification section of the node change track superposed for the first time, wherein the node identification section is a section of the node parameter change record in the node change track superposed for the first time, and the section corresponds to the identification.

Step S3223, acquiring a parameter mapping value and an authority description value mapped in the track section by the evaluation index change record; based on the parameter mapping value and the authority description value mapped in the track section by the evaluation index change record, carrying out second superposition on the node change track which is superposed for the first time, and generating an authority node updating track of the data authority updating track; and extracting node features corresponding to each authority node from the authority node updating track, determining a node feature sequence corresponding to the node features according to the sequence from small to large of feature dimensions of each group of node features, and generating the information security evaluation features based on evaluation labels existing in the node feature sequence.

It can be understood that through the contents described in the above steps S3221 to S3223, trajectory superposition and feature extraction can be performed on a plurality of continuous trajectory sections of the data authority updating trajectory, so as to determine a node feature sequence. Therefore, the information safety evaluation features can be completely generated based on the evaluation labels in the node feature sequence, and partial loss of the information safety evaluation features is avoided.

On the basis of the above-mentioned step S31-step S33, the method further includes: determining the information security evaluation feature from a second hotspot sharing request queue obtained currently, wherein the second hotspot sharing request queue and the first hotspot sharing request queue both contain the information security evaluation feature, and determining a current access authority request record of the information security evaluation feature; and caching the characteristic correction result when determining to perform characteristic correction aiming at the information security evaluation characteristic according to the current access authority request record of the information security evaluation characteristic. Therefore, by caching the characteristic correction results of the information security evaluation characteristics corresponding to different hotspot sharing request queues, accurate and rapid characteristic restoration can be realized through the cached characteristic correction results when the subsequent characteristics are lost, so that the interruption of the subsequent access verification is avoided.

In practical application, the inventor finds that different message transmission environments and message transmission behaviors need to be considered when determining the access intrusion detection result, so that the missed detection of the hotspot sharing request can be avoided. To improve this technical problem, the determining, based on the information security evaluation feature, an access intrusion detection result corresponding to the hotspot sharing request in each information communication network in the set of information communication networks, which is described in step S33, may further include the following steps S3311 to S3313.

Step S3311, determining a feature validity period and an information security label of an information security evaluation feature, determining a plurality of event label combinations according to a plurality of evaluation event labels in historical security evaluation results, performing label matching rate calculation according to the label association degree of each evaluation event label in each event label combination with the information security label in the feature validity period, obtaining a plurality of label matching rate calculation results respectively corresponding to the plurality of event label combinations, and taking a label heat weighted value of the event label combination corresponding to each label matching rate calculation result as a weighted value of each label matching rate calculation result.

Step S3312, based on the multiple label matching rate calculation results, respectively obtaining the message transmission records of each information communication network corresponding to the information security label determined in the feature validity period, obtaining multiple message transmission records, according to the weight value of each label matching rate calculation result, integrating the multiple message transmission records obtained based on the multiple label matching rate calculation results, obtaining a first message transmission record set, wherein the label heat weighted values between any two evaluation event labels in each event label combination are equal, the label heat weighted values corresponding to different event label combinations are different, each label matching rate calculation result is used for determining the access path risk rate corresponding to the hotspot sharing request in each information communication network corresponding to the information security label in any set time step length, and the label matching rate calculation result is obtained by calculating the label matching rate according to the historical safety evaluation result.

Step S3313, according to the historical security evaluation result and the access path risk rate of the multiple hotspot sharing requests corresponding to the information security label, acquiring a fusion identification result between the multiple hotspot sharing requests and the information security label within the feature validity period, and taking a target request message corresponding to the fusion identification result corresponding to the multiple hotspot sharing requests as a second message transmission record; and calculating the transmission record correlation degree of the first message transmission record set and the second message transmission record, and determining an access intrusion detection result corresponding to each hotspot sharing request according to the transmission record correlation degree and the access path risk rate of each hotspot sharing request.

Thus, by executing the steps S3311 to S3313, the feature validity period of the information security evaluation feature and the information security label can be analyzed and calculated, so as to determine the correlation degree of the transmission records between different message transmission records, and thus, the access intrusion detection result corresponding to each hotspot sharing request can be determined based on the correlation degree of the transmission records and the access path risk rate of each hotspot sharing request. Therefore, when the access intrusion detection result is determined, different message transmission environments and message transmission behaviors can be considered, and missing detection of the hotspot sharing request is avoided.

Further, on the basis of the step S3313, determining an access intrusion detection result corresponding to each hotspot sharing request according to the transmission record correlation and the access path risk rate of each hotspot sharing request may exemplarily include the following steps S3313 a-S3313 d.

Step S3313a, determining path node information of the sharing request transmission path corresponding to each hotspot sharing request based on the transmission record correlation, and determining access period information of each hotspot sharing request according to the risk triggering period of the access path risk rate of each hotspot sharing request in the corresponding information communication network; extracting a first description information list corresponding to the path node information and a second description information list corresponding to the access period information, and determining a plurality of information units with different feature description values respectively included in the first description information list and the second description information list; wherein the information unit is one piece of description information in the first description information list and the second description information list.

Step S3313b, on the premise that the list structure feature of the first description information list is the same as the list structure feature of the second description information list, obtaining the sharing request attribute information of the path node information in any information unit of the first description information list, and determining an information unit having the smallest feature description value in the second description information list as a target information unit in parallel; based on an encryption protocol of a request message field of each hotspot sharing request, adding the sharing request attribute information to the target information unit, and determining sharing request mapping information corresponding to the sharing request attribute information in the target information unit; and generating an information matching list between the path node information and the access period information according to request permission difference information between the sharing request attribute information and the sharing request mapping information.

Step S3313c, obtaining target execution function information in the target information unit with the sharing request mapping information as reference information, adding the target execution function information to the information unit where the sharing request attribute information is located according to a plurality of information matching paths corresponding to the information matching list, to obtain a function execution result corresponding to the target execution function information in the information unit where the sharing request attribute information is located, and determining the function execution result as an information access result according to the reference information; and the target execution function information is information of an execution function corresponding to the access action, and the information access result is used for representing the access result of the current hotspot sharing terminal.

Step S3313d, determining a corresponding information comparison result when the sharing request attribute information is added to the target information unit; according to the relevance between the function execution result and the field time sequence feature tags corresponding to the comparison nodes in the information comparison result, sequentially acquiring the intrusion detection tags corresponding to the information access result in the second description information list according to the sequence of time sequence weights from large to small, stopping acquiring the intrusion detection tags in the next information unit until the acquired information security level of the information unit where the intrusion detection tags are located is consistent with the information security level of the information access result in the first description information list, establishing the corresponding relation between the information access result and the intrusion detection tags acquired last time, and determining the access intrusion detection result corresponding to each hotspot sharing request based on the corresponding relation.

It is understood that, by executing the above-mentioned steps S3313 a-S3313 d, it is possible to determine the path node information of the sharing request transmission path corresponding to each hotspot sharing request based on the transmission record correlation degree, and determine the access period information of each hotspot sharing request through the risk triggering period of the access path risk rate of each hotspot sharing request in the corresponding information communication network. Therefore, the information matching list of the path node information and the access time interval information can be obtained, the corresponding relation between the information access result and the intrusion detection label obtained at the last time is established based on the information matching list, and the access intrusion detection result corresponding to each hotspot sharing request can be determined based on the corresponding relation. Therefore, the access intrusion detection result comprehensively considers the shared request transmission path and the access path risk rate, and the access intrusion detection result is difficult to tamper.

In some examples, the inventors have also found that in order to obtain an accurate and reliable identification result, it is necessary to consider the identification timeliness and the correlation between different detection tags accessing the intrusion detection result. To achieve the above object, the identifying the access intrusion detection result by using the preset artificial intelligence model described in step S33 to obtain the identification result may further include the following steps S3321 to S3325.

Step S3321, determining a timeliness index of a training set of a preset artificial intelligence model, updating the training set according to a recognition result of a previous period when the timeliness index does not reach a set index, inputting the access intrusion detection result into the preset artificial intelligence model when the timeliness index reaches the set index, and judging whether an early warning result output by the preset artificial intelligence model is received or not; and determining the previous period according to the set time step.

Step S3222, when an early warning result output by the preset artificial intelligence model is received, an authority detection thread is created according to the early warning result; and when the classification result corresponding to the intrusion detection classification label is output by a preset artificial intelligence model, determining the thread input parameters of the classification result corresponding to the intrusion detection classification label in the authority detection thread.

Step S3223, when it is determined that the thread input parameter of the classification result corresponding to the intrusion detection classification label in the authority detection thread is a dynamic input parameter or a static input parameter in a set category, directly loading the classification result corresponding to the intrusion detection classification label into a to-be-processed parameter set of the authority detection thread, or after loading the classification result corresponding to the intrusion detection classification label into a parameter conduction data set of a preset artificial intelligence model, conducting the classification result corresponding to the intrusion detection classification label into the to-be-processed parameter set of the authority detection thread through the preset artificial intelligence model; and operating the authority detection thread, and acquiring the access authority distribution information of the current hotspot sharing terminal, which is output after the authority detection thread extracts the authority list of the classification result.

Step S3324, determining the authority distribution record of the access authority distribution information and each authority verification code; and under the condition that the access authority distribution information contains the decryption label according to the authority distribution record, determining a correlation coefficient between each authority verification code under the encryption label of the access authority distribution information and each authority verification code under the decryption label of the access authority distribution information according to the authority verification code under the decryption label of the access authority distribution information and verification logic information thereof, and distributing the authority verification code under the encryption label of the access authority distribution information and the authority verification code under the decryption label to the decryption label.

Step S3325, extracting a first verification code queue corresponding to the authority verification code of the decryption tag and a second verification code queue corresponding to the authority verification code under the encryption tag, determining fusion queue characteristics of the first verification code queue and the second verification code queue, inputting the fusion queue characteristics into the preset artificial intelligence model, and obtaining an identification result of the preset artificial intelligence model for identifying and outputting the fusion queue characteristics.

It can be understood that by performing the above steps S3321 to S3325, the training set can be updated based on the timeliness index of the training set of the preset artificial intelligence model, thereby ensuring the recognition timeliness. The correlation coefficient of different authority verification codes under the decryption label and the encryption label can be considered, so that the correlation between different detection labels accessing the intrusion detection result is considered. Therefore, the identification result can be accurately and reliably obtained by integrating the identification timeliness and the correlation among different detection labels accessing the intrusion detection result.

In one possible example, the step S33 of accessing, according to the identification result, the target terminal that initiates the corresponding hotspot sharing request to the hotspot network corresponding to the current hotspot sharing terminal includes: and when the identification result represents that the corresponding hotspot sharing request has no abnormal access behavior, accessing the target terminal initiating the corresponding hotspot sharing request into a hotspot network corresponding to the current hotspot sharing terminal. Therefore, the information security of the current hotspot sharing terminal during hotspot sharing can be ensured.

In a conceivable embodiment, in order to continuously ensure the information security of the current hotspot sharing terminal when sharing the hotspot, on the basis of the above steps S31-S33, the following steps S34-S36 may be further included.

Step S34, monitoring a service processing process of the target terminal in the hotspot network, wherein in the process of monitoring the service processing process of the target terminal, an information invoking frequency of the target terminal in the hotspot network is determined.

Step S35, acquiring the current service interaction record corresponding to the service processing process of the target terminal based on the information calling frequency; extracting record updating information from the current business interaction record; and judging whether the interaction record in the current business interaction record has an interaction object change relative to the interaction record in the last business interaction record of the current business interaction record.

Step S36, if yes, determining the record update information extracted from the current service interaction record as the effective record update information of the current service interaction record; otherwise, overlapping the record updating information extracted from the current service interaction record with the effective record updating information of the last service interaction record at the corresponding time interval, and determining the overlapping result as the effective record updating information of the current service interaction record; when the abnormal access identification exists in the effective record updating information, sending prompt information to the current hotspot sharing terminal; the prompt message is used for indicating the current hotspot sharing terminal to intercept the hotspot sharing operation of the target terminal.

It can be understood that, by executing the steps S34 to S36, the valid record update information corresponding to the target terminal can be continuously monitored, so that when the abnormal access identifier is monitored, the current hotspot sharing terminal is instructed to intercept the hotspot sharing operation of the target terminal, and thus, the information security of the current hotspot sharing terminal when sharing the hotspot can be continuously ensured.

In an embodiment, the information communication network where the hotspot sharing request is determined from the obtained first hotspot sharing request queue as described in step S31 may be as described in the following steps S311 to S314.

Step S311, determining forwarding path information of each hotspot sharing request in the first hotspot sharing request queue according to the first hotspot sharing request queue; calculating and obtaining the request field of each hotspot sharing request in the first hotspot sharing request queue by using a preset communication network analysis model, and obtaining the field time sequence characteristics of each request field; wherein the field timing characteristics include dynamic timing characteristics and static timing characteristics.

Step S312, determining and obtaining the field timing characteristics of the mapping request field corresponding to each request field by using the pre-stored timing distribution record according to the field timing characteristics of each request field.

Step 313, according to the field timing characteristics of each request field and mapping request field, respectively determining whether the number of path nodes from each request field to the forwarding path information is greater than the number of path nodes from the corresponding mapping request field to the forwarding path information.

Step S314, if yes, acquiring the field time sequence characteristics of the mapping request field corresponding to the request field, and using the field time sequence characteristics as the field time sequence characteristics of the request field; if not, keeping the field time sequence characteristics of the request field unchanged; and determining the information communication network with the minimum time delay with the determined field time sequence characteristics of the request field as the information communication network where the hotspot sharing request corresponding to the request field is positioned.

In this way, based on the content described in the above steps S311 to S314, the information communication network where each hotspot sharing request is located can be accurately determined based on the timing delay.
