Detailed Description
As shown in fig. 1, an embodiment of the present invention provides a log security export method based on a self-service terminal device. The execution main body of the method is self-service terminal equipment, and the aim is to safely and efficiently acquire the log file of the self-service terminal equipment. In this embodiment, the self-service terminal device may be an automatic vending machine, an automatic teller machine, an automatic consulting machine, or the like. The method also requires a storage device and a service end. The storage device is preferably a USB, a mobile hard disk or other mobile storage device, which can be conveniently carried and can perform data transmission with other devices. The server is an intelligent terminal such as a computer or a smart phone, and log export software for exporting log files is loaded on the server. The storage device can be in communication connection with the self-service terminal device and the server side to transmit data. In this embodiment, the storage device is a USB memory.
The specific process of the log security export method based on the self-service terminal device provided by this embodiment is as follows.
When the self-service terminal equipment is abnormal and technicians need to acquire log files of the self-service terminal equipment to diagnose and check the abnormality, the workers at fault points can be requested to connect the USB memory to the USB interface of the self-service terminal equipment to establish connection between the USB memory and the self-service terminal equipment. The self-service terminal equipment reads the hardware information of the USB memory, then encrypts the hardware information, generates a first configuration file after encryption, and stores the first configuration file into the USB memory. The hardware information comprises a hardware serial number, a manufacturer ID and a product ID, the hardware serial number and the product ID are unique in the same series of products of the same manufacturer, one hardware serial number and one product ID only correspond to one product, and one storage device can be uniquely determined through the hardware serial number, the manufacturer ID and the product ID.
And then pulling out the USB memory, connecting the USB memory with the server, operating log export software on the server, decrypting the first configuration file by the log export software, and then carrying out data format verification on the decrypted file. The data format check means whether the data format of the first configuration file is the same as a preset data format, and the data format check may be preset in the form of characters or binary numbers. And if the data format of the first configuration file is the same as the preset data format, the data format is verified to be passed, and the next step is executed. And if the data format of the first configuration file is different from the preset data format, the data format is checked to be failed, the export process is finished, and the log file is failed to be exported.
After the data format is verified, the server writes export configuration information and valid range information in the first configuration file to generate a second configuration file. The export configuration information comprises log types and log grades, wherein the log types and the log grades are used for dividing different events by the self-service terminal equipment, dividing the events generated by the system into various categories and arranging the categories according to the grades so as to facilitate management. In this embodiment, the export configuration information is used to control the self-service terminal device to export the log files of the corresponding types and the corresponding levels, so that automatic export is realized, and the security and the log export efficiency are improved. The valid range information comprises the valid time of the second configuration file, the log exportable times and the self-service terminal device number. The valid time may be a certain time node or a certain time period. The valid time means that the second configuration file is valid before a certain time node or within a certain time period, and the second configuration file is considered invalid when the time node is exceeded or the second configuration file is not within the certain time period. The log exportable time refers to the number of log exportable operations that can be performed by the second configuration file, and the second configuration file can perform the log exportable operation only when the log exportable time is greater than zero. The self-service terminal equipment number is used for designating a certain self-service terminal equipment, so that the second configuration file can only carry out log export operation on the designated self-service terminal equipment.
And after the server generates the second configuration file, encrypting the second configuration file, and storing the encrypted second configuration file in the USB memory. And connecting the USB memory with the self-service terminal equipment. The self-service terminal device decrypts the second configuration file and then verifies the valid range information in the second configuration file, and the specific verification process is as follows.
The verification process comprises the following steps: and verifying the valid time, the log derivable times and the self-service terminal equipment number.
The self-service terminal equipment checks whether the current time point is within the valid time, if the valid time is preset to be a certain time point, whether the current time point is before the preset time point is checked, if yes, the valid time is checked to be passed, and if not, the valid time is checked to be not passed. If the effective time is preset to a certain time period, checking whether the current time point is within the preset time period, if so, passing the effective time check, otherwise, failing to pass the effective time check. That is, a certain second configuration file is valid only within the valid time, and if the valid time is exceeded, the log file cannot be exported through the second configuration file, so that the log file is effectively protected, and the security in the process of exporting the log file is improved.
And the self-service terminal equipment checks whether the log exportable times of the second configuration file are greater than zero, if so, the log exportable times check is passed, and if not, the log exportable times check is not passed. That is, the number of times that a single second configuration file can export a log file is limited, and the log file cannot be exported for an unlimited number of times through the single second configuration file, so that the security in the log export process is improved.
And the self-service terminal equipment checks whether the self-service terminal equipment number is consistent with the self-service terminal equipment number in the second configuration file, if so, the self-service terminal equipment number passes the check, and if not, the self-service terminal equipment number does not pass the check. The log file can be only exported from the designated self-service terminal equipment by the single second configuration file, and the self-service terminal equipment can only export the log file under the control of the second configuration file with the serial number of the self-service terminal equipment, so that the safety of the log file in the export process can be improved.
And only when the valid time check, the log exportable times check and the self-service terminal equipment number check are passed, the valid range information check of the second configuration file is passed, otherwise, the valid range information check is regarded as not passed, the log exporting process is ended, and the log file exporting fails. Through the process, the export of the log file is strictly verified, and the safety of the log file in the export process can be improved.
And after the effective range information of the second configuration file passes the verification, the self-service terminal equipment can verify the hardware information of the USB memory. The self-service terminal device reads the hardware information of the USB memory, and compares the hardware information with the hardware information in the second configuration file. The hardware information in the second configuration file is the hardware information of the USB memory connected with the self-service terminal equipment in the initial step. The self-service terminal equipment reads the hardware information of the currently connected USB memory, compares the hardware information with the hardware information of the previously connected USB memory, performs the next step if the comparison result is consistent, and ends the export process if the comparison result is inconsistent, and the log export fails. The step is mainly to ensure the consistency of the two storage devices connected in front and at the back, prevent other storage devices from exporting the log file after copying the second configuration file, effectively prevent other untrusted storage devices from exporting the log file from the self-service terminal device, and have higher safety.
For the comparison process of the effective range information check of the second configuration file and the hardware information, it can be understood that the log file can be exported from the self-service terminal device only when the authorized storage device stores the effective second configuration file, so that the security of the log file is greatly improved.
After the hardware information comparison is passed, the self-service terminal device can judge whether the export configuration information in the second configuration file is correct. The derived configuration information includes a log type and a log level. The self-service terminal equipment judges whether the log type and the log grade in the derived configuration information are consistent with the log type and the grade division of the self-service terminal equipment, if so, the judgment is correct, and the next step is executed; if the log is not matched with the log, the log is judged to be incorrect, the export process is ended, and the log export process fails. The configuration information is exported for the self-service terminal equipment to automatically export the log files of the corresponding types and the corresponding levels according to the information, so that technicians do not need to arrive at a fault site for operation, the fault processing efficiency is improved, and the maintenance cost is reduced.
After judging that the export configuration information is correct, the self-service terminal equipment encrypts and exports the log files of the corresponding types and the corresponding levels to the storage equipment according to the export configuration information, reduces the exportable times of the second configuration file by one, and then encrypts and stores the modified second configuration file to the storage equipment. This completes the log file export process. When the export is finished, the log file and the second configuration file are respectively encrypted, so that the log file can be protected, the log file is prevented from being leaked or tampered, the second configuration file is prevented from being tampered, and the safety is improved.
It will be apparent to those skilled in the art that various other changes and modifications may be made in the above-described embodiments and concepts and all such changes and modifications are intended to be within the scope of the appended claims.
