Description

Technical Field

[0001] The embodiments of the present application belong to the field of computer technology, and in particular, relate to a method for managing application library files, a cloud server, a network device, and a storage medium. Background Art

[0002] The application library file is one of the main configuration files used by the network device when implementing the firewall function. Users can configure different security policies for the firewall function in the network device through the application library file. When the network device performs the firewall function, the application library file can be used to identify which application the data packet flowing through belongs to, and determine whether to allow the data packet to be transmitted according to the security policy corresponding to the application. In the prior art, in order to facilitate users to configure the security policy of the network device using the application library file, each network device that performs the firewall function will upload and save the application library file stored in itself to the cloud server after being enabled. In addition, the network device will actively upload and save the updated application library file to the cloud server after each application library file is updated. However, the application library file uploaded by the network device may not be used by the user. And different network devices can perform security protection operations on the same batch of applications, that is, the application library files uploaded by different network devices can be the same. Therefore, the method provided by the prior art not only causes the cloud server to store a large number of unused application library files, but also causes the cloud server to store a large number of identical application library files, thereby reducing the storage space efficiency of the cloud server.

[0049] In the following description, specific details such as specific system structures, technologies, etc. are proposed for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the present application.

[0050] The technical solution of the present application is described below through specific embodiments.

[0051] See also Figure 1 , shows a schematic diagram of a network device management system provided by an embodiment of the present application. Figure 1 As shown, the network device management system may include a cloud server and N network devices with firewall functions. Wherein, N may be a positive integer greater than or equal to 1. The cloud server may be respectively connected to each network device for communication. The cloud server in this embodiment may be any server capable of providing computing or application services to a terminal device, and the network device may be any device capable of performing a firewall function, such as a hardware device specifically used to monitor and filter data packets entering and leaving the network, a router with a firewall application installed, or a terminal device with a firewall application installed.

[0052] Reference Figure 2 , shows a schematic diagram of a method for managing an application library file provided in an embodiment of the present application. The application library file provided in an embodiment of the present application can be applied to any network device management system. The above-mentioned method for managing an application library can specifically include the following steps:

[0053] S201. The cloud server responds to a file acquisition instruction initiated by a user and searches a preset storage unit for an application library file corresponding to the first file identifier according to the first file identifier in the file acquisition instruction.

[0054] In this embodiment, when a user needs to configure a security policy for a network device, for example, when a user needs to configure a security policy on a network device that prohibits a terminal device with a certain network address from transmitting data packets to a server where application A is located, since the application library file used on the network device stores application information of at least one application supported and recognized by the network device, the user needs to first obtain the application library file used on the network device, and then configure the security policy according to the application library file. At this time, the user can send a file acquisition instruction to the cloud server through the network device management webpage on the terminal device to obtain the application library file used by the network device that needs to configure the security policy. Exemplarily, the network device management webpage may include a file acquisition button. When the user needs to obtain the application library file, the user can select the file acquisition button on the terminal device, and the terminal device can initiate a file acquisition instruction to the cloud server in response to the user's selection operation of the file acquisition button. The cloud server can respond to the file acquisition instruction initiated by the user, and query the application library file corresponding to the first file identifier from the preset storage unit according to the first file identifier in the file acquisition instruction. Among them, the storage unit can be a memory on the cloud server, or a database server preset by the R&D personnel.

[0055] In a possible implementation, if the cloud server determines that the storage unit contains the application library file corresponding to the first file identifier, the cloud server can obtain the application library file corresponding to the first file identifier from the storage unit. Then, the cloud server can send the application library file corresponding to the first file identifier to the terminal device that initiates the file acquisition instruction, so that the user can configure the security policy according to the application library file.

[0056] S202: If the cloud server determines that the storage unit does not contain the application library file corresponding to the first file identifier, the cloud server queries at least one target network device corresponding to the first file identifier based on a mapping relationship between the application library file and the device.

[0057] In this embodiment, if the cloud server determines that the storage unit does not contain the application library file corresponding to the first file identifier, the cloud server can query at least one target network device corresponding to the first file identifier based on the mapping relationship between the application library file and the device. The mapping relationship can record the second file identifier corresponding to the application library file used by each network device. The mapping relationship between the application library file and the device can be stored in a database preset by the R&D personnel, such as a Mysql database.

[0058] S203: The cloud server sends a file acquisition request including a first file identifier to the target network device according to a preset communication protocol.

[0059] In this embodiment, after determining the target network device, the cloud server can generate a file acquisition request according to the device identifier corresponding to the target network device and the first file identifier corresponding to the file acquisition instruction. Then, the cloud server can send the file acquisition request including the first file identifier to the target network device through the communication protocol between the cloud server and the target network device. Exemplarily, the communication protocol between the cloud server and the target network device can be a Secure Sockets Layer (SSL) protocol.

[0060] In one possible implementation, referring to Figure 3 , shows a schematic diagram of a specific method for a cloud server to obtain an application library file provided by an embodiment of the present application. Figure 3 As shown, when the cloud server determines that the storage unit does not contain the application library file corresponding to the first file identifier, the cloud server can query the mapping relationship between the application library file and the device based on the first file identifier, and use the network device corresponding to the second file identifier that is the same as the first file identifier in the mapping relationship as the target network device. Exemplarily, the cloud server can query at least one target network device from the database based on the first file identifier. Then, the cloud server can determine whether the number of the queried target network devices is greater than the number threshold preset by the R&D personnel. Exemplarily, the number threshold can be 1.

[0061] If the cloud server determines that the number of target network devices is equal to the number threshold, the cloud server can directly generate a file acquisition request based on the device identifier corresponding to the currently determined target network device, the first file identifier, and the communication protocol pre-set by the R&D personnel, and send the file acquisition request to the target network device. If the cloud server determines that the number of target network devices is less than the number threshold, the cloud server can generate an error prompt message and send the generated error prompt message to the terminal device that initiated the file acquisition instruction. Among them, the error prompt message generated by the cloud server can be used to indicate that the application library file corresponding to the first file identifier does not exist.

[0062] If the cloud server determines that the number of target network devices is greater than the number threshold, the cloud server obtains the write time of the second file identifier corresponding to each target network device into the database. Then, the cloud server can determine the request order corresponding to each network device according to the write time corresponding to each target network device. Exemplarily, the cloud server can sort each network device from the latest to the earliest according to the write time, and use the sorting result as the request order corresponding to each network device. After determining the request order corresponding to each network device, the cloud server can send a file acquisition request to each target network device in turn according to the communication protocol, the request order and the waiting time pre-set by the R&D personnel until receiving the application library file sent by any target network device based on the file acquisition request. Specifically, the cloud server can continue to receive the feedback information of the target network device currently sending the file acquisition request according to the waiting time after each file acquisition request is sent. If the cloud server does not receive the application library file fed back by the target network device within the waiting time, the cloud server can send a file acquisition request to the target network device of the next request order. If the cloud server receives the application library file fed back by the target network device within the waiting time, the cloud server can stop sending the file acquisition request to the target network device of the next request order.

[0063] In this embodiment, since the cloud server can send file acquisition requests to each target network device that uses the application library file corresponding to the first file identifier in turn, even if a target network device encounters problems such as network connection interruption, the cloud server can still obtain the application library file from other target network devices, thereby ensuring the stability of obtaining the application library file.

[0064] Exemplarily, the cloud server may first send a file acquisition request to the target network device of the first request order, and continue to receive information fed back by the target network device of the first request order according to the file acquisition request based on the waiting time. If the cloud server receives the application library file sent by the target network device of the first request order within the waiting time, the cloud server may determine that the application library file has been successfully acquired, and the cloud server may stop sending the file acquisition request. If the cloud server does not receive the application library file sent by the target network device of the first request order within the waiting time, or receives an error message sent by the target network device, the cloud server may send a file acquisition request to the target network device of the next request order, and the cloud server may send the file acquisition request to each target network device in turn according to the request order until the application library file fed back by any target network device is received.

[0065] In one possible implementation, see Figure 4, shows a schematic diagram of the structure of a cloud server provided in an embodiment of the present application. Figure 4 As shown, the cloud server may include a configuration module, a file management module, a message center module, a message processing module, a file import and export module, and an access module.

[0066] Specifically, the configuration module on the cloud server may include a configuration management submodule, an object management submodule, and a device management submodule. The configuration management submodule may be used to provide a configuration management interface for the web page, and update the security policy in the network device after going online according to the user's configuration operation. The configuration management submodule may also call the file management module in response to the file acquisition instruction initiated by the user, so as to query and obtain the application library file corresponding to the file acquisition instruction from the storage unit through the file management module. When the storage unit does not contain the application library file corresponding to the file acquisition instruction, the configuration management submodule may also send a file acquisition request to the file import and export module, so as to request the application library file from the network device through the file import and export module. The device management submodule may be used to perform operations such as updating, saving, and deleting on the device information of the network device after going online. Specifically, the device management submodule may write the device information in the online information into a preset database for storage. The device management submodule may also perform an update operation on the device information stored in the database according to the received update event, such as the application library update event. The object management submodule may update the mapping relationship between the application library file and the device in response to the application library update event sent by any network device.

[0067] The message center module on the cloud server can be used to receive various data packets sent by any network device, such as online information, application library update events, device information update events, network abnormal events, network device failure events, system service status change events, etc., and forward the received messages to the corresponding message processing module so that the message processing module can perform corresponding operations on the received data packets.

[0068] The message processing module on the cloud server may include at least an event distribution submodule and an online processing submodule. Among them, the event distribution submodule in the message processing module can be used to receive various events forwarded by the message center module, such as application library update events, device information update events, network abnormality events, network device failure events, system service status change events, etc. The event distribution submodule can also distribute the various events received to the corresponding processing functions or modules for further processing. For example, when the event distribution submodule in the message processing module receives the application library update event sent by the message center module, the event distribution submodule can distribute the received application library update event to the configuration module, so that the configuration module updates the mapping relationship between the application library file and the device according to the application library update event. After receiving the online information forwarded by the message center module, the online processing submodule in the message processing module can perform online operations on the received online information, for example, write the device information in the online information into the database pre-set by the R&D personnel and other operations.

[0069] The file import and export module on the cloud server can be used to send a file acquisition request to the network device through a communication protocol with the network device. Then, the cloud server can receive the application library file sent by the network device based on the file acquisition request through the file management module.

[0070] The access module on the cloud server can be used to provide multiple interfaces, for example, to provide a communication interface for the file import and export module, such as a Passthrough API, so that the file import and export module can access the communication protocol between the network device through the communication interface.

[0071] The file management module on the cloud server can be used to receive application library files sent by any network device based on a file acquisition request, and perform management operations such as storage, deletion, and query on the received application library files.

[0072] Through the method provided in this embodiment, since the cloud server may include multiple different modules, each module is used to perform a specific operation, the method provided in this embodiment can improve the maintainability, scalability and reusability of the cloud server.

[0073] S204: The network device receives a file acquisition request including a first file identifier sent by a cloud server according to a preset communication protocol.

[0074] In this embodiment, the network device may receive a file acquisition request including a first file identifier sent by the cloud server according to a communication protocol with the cloud server. After receiving the file acquisition request, the network device may determine whether the first file identifier in the currently received file acquisition request matches the second file identifier of the locally used application library file. Among them, after the network device updates the application library file for a certain time, the application library event sent by the network device to the cloud server may fail due to reasons such as network connection interruption. At this time, the second file identifier corresponding to the network device in the mapping relationship stored in the cloud device may be inconsistent with the actual second file identifier used by the network device. If the network device determines that the first file identifier does not match the second file identifier of the locally used application library file, the network device may not send the application library file to the cloud server, and return an error message to the cloud server, so that the cloud server sends a file acquisition request to other network devices.

[0075] In one possible implementation, when the network device determines that the first file identifier does not match the second file identifier of the application library file used locally, the network device may also send an application library update event to the cloud server to update the second file identifier corresponding to the network device in the mapping relationship stored on the cloud server.

[0076] S205: If the network device determines that the first file identifier matches the second file identifier of the locally used application library file, the network device sends the application library file to the cloud server according to the communication protocol.

[0077] In this embodiment, if the network device determines that the first file identifier matches the second file identifier of the locally used application library file, the network device can send the application library file to the cloud server according to the communication protocol preset by the R&D personnel.

[0078] S206: The cloud server receives the application library file uploaded by the target network device based on the file acquisition request.

[0079] In this embodiment, the cloud server can receive the application library file uploaded by the target network device based on the file acquisition request. The cloud server can send the received application library file to the terminal device used by the user, so that the user can configure the security policy according to the application library file.

[0080] Through the method provided in this embodiment, the cloud server will only obtain an application library file from a network device when a user needs the application library file, and will not save all the application library files used by all network devices to the cloud server in advance. Therefore, the method provided in this embodiment can reduce the memory pressure of the cloud server and reduce disk space consumption. Since the prior art will save the application library files used by all network devices to the cloud server in advance, if the user has not used a certain application library file, the application library file is a useless file, but because it is stored in the cloud server, the cloud server also needs to consume resources to manage the useless application library file. It can be seen that the method provided in this embodiment can also avoid the cloud server from managing useless files, thereby improving the management resource utilization of the cloud server.

[0081] In a possible implementation, after receiving the application library file sent by the target network device, the cloud server can also write the received application library file and the file identifier corresponding to the application library file into the storage unit for storage. The cloud server can also periodically obtain the third file identifiers corresponding to each stored library file stored in the storage unit according to the data clearing cycle pre-set by the R&D personnel. Among them, the stored library file can be any application library file after the cloud server writes the storage unit. For any third file identifier in the storage unit, the cloud server can determine whether the mapping relationship between the application library file and the device contains the third file identifier. If the cloud server determines that the mapping relationship between the application library file and the device does not contain the third file identifier, the cloud server can delete the stored library file corresponding to the third file identifier in the storage unit. If the cloud server determines that the mapping relationship between the application library file and the device contains the third file identifier, the cloud server can retain the stored library file corresponding to the third file identifier in the storage unit.

[0082] For example, when a certain network device is online, the second file identifier corresponding to the application library file it uses is A1. When the user needs to configure a security policy for the network device, the cloud server can obtain the application library file with the second file identifier A1 from the network device, and write the application library file with the second file identifier A1 into the storage unit for storage. Later, the application library file used by the network device was updated, and the cloud database changed the second file identifier corresponding to the network device in the mapping relationship to A2 based on the received application library update event. When the cloud server performs a data clearing operation at a scheduled time, the cloud server finds that there is a stored library file with the third file identifier A1 in the storage unit, but finds that there is no network device with the second file identifier A1 corresponding to the used application library file in the mapping relationship between the application library file and the device. Therefore, the stored library file with the third file identifier A1 has expired, and the cloud server can delete the stored library file from the storage unit.

[0083] Through the method provided in this embodiment, after the cloud server pulls the application library file from a certain network device, the application library file can be written into the storage unit. When the subsequent user needs the application library file, the cloud can directly obtain the application library file from the storage unit without repeated uploading, so the method provided in this embodiment can reduce the consumption of transmission resources. In addition, the cloud server can regularly clean up useless application library files in the storage unit to free up disk space. Therefore, the method provided in this embodiment can reduce useless files in the storage unit and improve the utilization rate of storage space.

[0084] Figure 5 FIG. 2 shows a flowchart of another method for managing application library files provided in the second embodiment of the present application. Figure 5 , compared to Figure 1 In the embodiment, the management method of an application library file provided in the embodiment includes before S201: S501 to S504, which are described in detail as follows:

[0085] S501: The network device generates a second file identifier corresponding to the application library file based on the number of application program identifiers included in the application library file and summary information corresponding to the application library file.

[0086] In this embodiment, an application control feature library (Application Control Gateway, ACG) may be configured in a network device with a firewall function. Specifically, the application control feature library may be a database that stores multiple applications and feature information corresponding to each application. For any data packet flowing through the network device, the network device may identify and classify the application to which the data packet belongs based on the application control feature library. After the network device responds to a startup instruction initiated by the user and executes the initialization startup operation pre-set by the R&D personnel, it may generate an application library file based on the application control feature library used. Among them, the application library file generated by the network device may include application information corresponding to multiple applications that the network device supports and identifies.

[0087] Specifically, the application library file may include an application supported for a certain network device, and the application library file may include an application identifier, application name, subclass name, subclass identifier, and major category identifier, etc. corresponding to the application. Exemplarily, the program information of application A in the application library file may include application identifier 1001, subclass IM, and major category social entertainment. Exemplarily, the file format of the application library file generated by the network device may be any text file format, such as CSV format (Comma-Separated Values).

[0088] Among them, using CSV format as the file format of the application library file has the following benefits. (1) Simplicity: The structure of the CSV format is very simple. Each row represents a record, each column represents a field, and different fields are separated by commas (or other delimiters). This simplicity makes CSV format files easy for the human eye to read and write. (2) High versatility: CSV format files are supported by most databases, spreadsheet applications (such as Microsoft Excel, Google Sheets), and data analysis tools. Therefore, using CSV format files can easily exchange data between multiple systems. Therefore, it has extremely strong versatility. (3) Compatibility and persistence (4) Storage efficiency: Compared with files in other formats, CSV format files usually take up less disk space because they do not contain additional key names and brackets in JSON. Therefore, using CSV format can improve the storage efficiency of application library files.

[0089] After generating the application library file, the network device may also generate a second file identifier corresponding to the application library file according to the number of application program identifiers contained in the application library file and the summary information corresponding to the application library file. The structure of the second file identifier corresponding to a certain application library file may be: "number of application programs_first 16 bits of the summary information of the application library file".

[0090] In a possible implementation, when generating the second identifier, the network device may input all application program identifiers contained in the application library file into a preset information digest algorithm to generate summary information corresponding to the application library file through the information digest algorithm. The same information digest algorithm may be configured in each network device. Exemplarily, the information digest algorithm configured in the network device may be a cryptographic hash function (Message-Digest Algorithm 5, MD5). For example, when an application library file contains 6480 applications, and the first 16 bits of the summary information calculated by the cryptographic hash function of the application library file are 98e3306c3ad45410, the second file identifier corresponding to the application library file may be 6480_98e3306c3ad45410.

[0091] In this embodiment, since the summary information corresponding to the application library file is generated based on all application program identifiers and information summary algorithms contained in the application library file, and the information summary algorithms equipped on different network devices are the same, the method provided in this embodiment can ensure that the second file identifiers generated by application library files containing the same application program information in different network devices are the same, that is, the information in the application library file corresponding to the same second file identifier is completely consistent, thereby ensuring the consistency of the file identifier and the application library file.

[0092] S502: The network device generates online information based on the second file identifier in response to the online instruction initiated by the user, and sends the online information to the cloud server.

[0093] In this embodiment, when the user needs to upload the device information corresponding to the network device to the cloud server, the user can initiate an online instruction to the network device. Specifically, the user can enter the device identification and device password corresponding to the network device on which the online operation needs to be performed on the network device management webpage of the terminal device. The cloud server can establish a communication link with the network device corresponding to the device identification and device password based on the device identification and device password entered by the user, and initiate an online instruction to the network device through the communication link. The network device can respond to the online instruction initiated by the user, generate online information based on the second file identification and the device information corresponding to the network device, and send the online information to the cloud server according to the preset communication protocol. Among them, the device information may include but is not limited to the device identification corresponding to the network device, the device model, the device type, the software version of the application used by the network device, the hardware version and other information.

[0094] In a possible implementation, when a user needs to update the application control feature library on a network device, the user can click the update control on the management page of the network device and upload an update program for performing the update operation, so that the network device updates the application control feature library according to the update program. After updating the application control feature library, the network device can also generate a new application library file based on the updated application control feature library, and generate a second file identifier corresponding to the new application library file. Among them, the specific method of the second file identifier corresponding to the new application library file of the network device can refer to the relevant content of this embodiment, which will not be repeated here. Then, the network device can send an application library update event to the cloud server based on the newly generated second file identifier and the device identifier corresponding to the network device to update the mapping relationship stored in the cloud server. After receiving the application library update event sent by any network device, the cloud server can update the mapping relationship stored in the database according to the device identifier and the second file identifier in the application library update event.

[0095] Through the method provided in this embodiment, after the application control feature library in the network device is updated, the network device can send an application library update event to the cloud device to update the mapping relationship in the cloud server. Therefore, the method provided in this embodiment can improve the accuracy of the mapping relationship stored in the cloud server.

[0096] S503: The cloud server receives online information sent by any network device, and writes the device identifier in the online information and the second file identifier corresponding to the device identifier into the mapping relationship between the application library file and the device.

[0097] In this embodiment, the cloud server can receive the online information sent by each network device through the message center module. The cloud server can write the device identifier in the online information and the second file identifier corresponding to the device identifier into the mapping relationship between the application library file and the device. The cloud server can also write the device information contained in the online information into the database for storage, so as to facilitate the user to manage the network device through the cloud server.

[0098] In this embodiment, when the network device performs online operations and updates the application control feature library, it only needs to send the second file identifier corresponding to the application library file to the cloud server, and there is no need to send the application library file to the cloud server. Therefore, the method provided in this embodiment can greatly reduce the consumption of cloud server system resources.

[0099] It should be noted that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
