Description
Technical Field
The present application relates to the field of network technologies, and in particular, to a method and an apparatus for performing system security control.
Background
With the development of network technology, the security of network systems is becoming more and more important, wherein transaction security is an important aspect of the security of network systems. At present, users are more and more convenient and more common to conduct transactions through a network, and the network transactions bring convenience to the users and also bring certain risks, for example, the user account may be stolen to conduct online transactions.
In order to reduce the transaction risk of the user and realize the system safety control, the prior art generally compares the transaction times of the user in a longer time period in the past with the transaction times of the user in a shorter time period from the current time period to determine whether to allow the user to perform the transaction. For example, if a user is determined to have traded less than ten times in the past year (not including the day) and ten times in five minutes since the present time, then it is determined that the user's account may be misappropriated, and the user is therefore denied the current transaction.
However, since the transaction frequency of the user is different for different services, the accuracy of this method of performing system security control by considering the total transaction times of the user is low, for example, it is assumed that a user has two hundred transactions for different services in the past year, including several tens of purchases of snacks, several tens of daily supplies, several tens of purchases of movie tickets, several tens of clothes, and one purchase of package. However, within a few minutes of a day, the user conducts ten transactions for the package on the network, and according to the control method, the transactions for the package are continuously allowed because the transaction number is far less than the total transaction number in a year, and obviously, the transactions are not safe.
Therefore, the accuracy of the safety control of the system in the existing mode is low.

Detailed Description
In the embodiment of the application, the transaction object which is required to be transacted by the user currently is bound with the user, the transaction times of the two users in the previous first set time period and the transaction times of the two users in the latest second set time period are respectively determined, and the current transaction of the user is safely controlled according to the transaction times of the two users in the two set time periods. Because the frequency and the service types of transactions between a user and different transaction objects are usually different, the embodiment of the application binds the user and the transaction object which the user needs to perform the transaction currently, and only considers the transaction between the user and the same transaction object when performing security detection on the current transaction of the user, so that the security detection can be performed on the transaction which the user needs to perform currently based on a specific transaction object in a targeted manner, the accuracy of risk identification is improved, and the accuracy of system security control is further improved.
The embodiments of the present application will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, a flowchart of a method for performing system security control according to an embodiment of the present application includes the following steps:
s101: receiving a transaction request message sent by a user; the transaction request message includes information of a transaction object transacted with the user.
The execution subject of the embodiment of the application is a server for performing system security control.
In this step, after receiving a transaction request message sent by a user, a server extracts user information, such as account information that the user logs in, and information of a transaction object that the user needs to perform a transaction, such as a name or an account of the transaction object, for identifying the transaction object.
S102: determining the transaction times between the user and the transaction object in a first set time period and the transaction times between the user and the transaction object in a second set time period according to the stored transaction log; the second set time period is the time within the second set time period from the current time, the time of the first set time period is earlier than the time of the second set time period, and the length of the first set time period is longer than the length of the second set time period.
In this step, the server extracts transaction information about the transaction between the user and the transaction object of the user from the stored transaction log, where the transaction information includes transaction time information, and determines the transaction times about the transaction between the user and the transaction object of the user within the first set time period and the second set time period, respectively, according to the extracted transaction information, for example, the first set time period is a time within the last half year excluding the current day (i.e., the day on which the transaction request message sent by the user is received in S101), and the second set time period is a time within the last 10 minutes.
S103: and performing safety control on the current transaction of the user according to the transaction times in the first set time period and the transaction times in the second set time period.
In this step, the transaction frequency in the first set time period is compared with the transaction frequency in a second set time period, and if the transaction frequency of the user and the transaction object in the second set time period obviously does not accord with the transaction rule of the user and the transaction object in the first set time period, it indicates that the transaction between the user and the transaction object is at risk. For example, if the number of transactions of the user with a brand-name bag seller in the last half year (not including the current day) is one, but the number of transactions with the seller in the last 10 minutes is up to 20, which is much greater than the number of transactions of the user with the seller in the last half year, the current transaction of the user with the seller can be controlled, for example, the transaction of the user can be directly rejected; alternatively, the user may be authenticated with the security information, for example, the user inputs an answer to a preset security question, the answer input by the user is compared with an answer input by the previous user registration, and if the answer input by the user is consistent with the answer input by the previous user registration, it is determined that the user passes the security information authentication, and the user is allowed to perform the transaction.
The present application is further described below with reference to a specific embodiment, and details of the specific implementation are repeated in the above embodiment and are not repeated.
As shown in fig. 2, a flowchart of a method for performing system security control according to a second embodiment of the present application includes:
s201: receiving a transaction request message sent by a user; the transaction request message includes information of a transaction object transacted with the user.
S202: determining the transaction times between the user and the transaction object in a first set time period and the transaction times between the user and the transaction object in a second set time period according to the stored transaction log; the second set time period is the time within the second set time period from the current time, the time of the first set time period is earlier than the time of the second set time period, and the length of the first set time period is longer than the length of the second set time period.
S203: and determining a transaction risk coefficient according to the transaction times in the first set time period and the transaction times in the second set time period.
In this step, a sum of the transaction frequency and a preset value in a first set time period may be determined, where the preset value is greater than 0; and determining the ratio of the transaction times to the sum value in a second set time period as the transaction risk coefficient. That is, the transaction risk coefficient k may be determined according to the following formula:
In the above formula, the reason why the preset value α is added after the transaction frequency in the first set time period of the denominator part is to prevent the transaction risk coefficient k from being infinite when the transaction frequency in the first set time period is 0, and the system error report occurs. In this formula, the time within the first set time period is earlier than the time within the second set time period, and the length of the first set time period is longer than the length of the second set time period, for example, the first set time period is the last half year (excluding the day on which the user sends the transaction request message in S201), and the second set time period is the last 10 minutes.
S204: and performing safety control on the current transaction of the user according to the transaction risk coefficient.
In this step, according to the transaction risk coefficient, the following two ways of performing security control on the current transaction of the user may be used:
firstly, safety control is carried out based on a comparison result of the transaction risk coefficient and a set risk coefficient threshold;
specifically, when the transaction risk coefficient is smaller than a set risk coefficient threshold, the user is allowed to conduct the transaction, otherwise, the user is refused to conduct the transaction or the user is subjected to security information verification.
In this embodiment, the transaction risk coefficient calculated in S203 is directly compared with a preset risk coefficient threshold, and when the transaction risk coefficient is greater than or equal to the set risk coefficient threshold, it indicates that a risk exists in a transaction (i.e., a transaction requested by the user sending the transaction request message in S201) that the user currently needs to perform, and the user may be directly rejected to perform the transaction or perform security information verification on the user.
Secondly, performing safety control based on a preset safety control model;
specifically, inputting a plurality of control parameter values including the transaction risk coefficient into a preset safety control model;
and when the transaction risk score output by the safety control model is smaller than a set risk score threshold value, allowing the user to perform the transaction, otherwise, refusing the user to perform the transaction or performing safety information verification on the user.
In this embodiment, the user is subjected to security control based on a preset security control model, and the control parameters related to the security control model may include, in addition to the transaction risk coefficient, other parameters, such as a trusted environment type parameter (such as a MAC address) of the user transaction, a transaction type parameter (such as a transaction amount), and the like. For example, a Media Access Control (MAC) address of a terminal device used by a user (the user may be uniquely identified by account information registered by the user) for performing the transaction may be compared with a MAC address of the terminal device used by the user for performing the transaction in the last half year (not including the current day), if the MAC address of the terminal device used by the user for performing the transaction is not included in the MAC address of the terminal device used by the user for performing the transaction in the last half year (not including the current day), the MAC address risk value (belonging to the trusted environment type parameter value) may be set to 1, otherwise, the MAC address risk value may be set to 0. For another example, if the transaction amount of the transaction between the user and the transaction object required for the transaction at this time exceeds ten times of the transaction amount of the transaction between the user and the transaction object in the last half year (not including the current day), the transaction amount risk value may be set to 1, otherwise, the transaction amount risk value may be set to 0.
In specific implementation, collecting all control parameter values related to the preset safety control model, and inputting the control parameter values including the transaction risk coefficient into the safety control model to obtain a transaction risk score; and then, according to the transaction risk score, judging the risk degree of the user for carrying out the transaction. In a specific implementation, the safety control model may be set according to actual conditions, and simply, the value output by the safety control model may be a value obtained by weighted addition of various control parameter values.
