[0002] In today's digital age, the Internet has already penetrated into every aspect of people's lives. From work communication, academic research to daily shopping, entertainment and leisure, it has become normal for netizens to access the Internet through browsers. As a bridge connecting users and the Internet, the security of browsers plays a vital role in protecting user information security and maintaining cyberspace security.

[0003] In daily use, users often need to download files through browsers. These files may come from email attachments, network disk sharing, software download sites, etc. Although these activities seem normal, they hide security risks that cannot be ignored. Malware, including viruses, Trojans, spyware, adware, etc., often spread by disguising themselves as normal files. Once users accidentally download and execute these malicious files, personal privacy leaks, property losses, and even corporate security incidents may occur.

[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] Among them, in the traditional solution of downloading files through a browser, local security checks are used to defend against threats such as malware, such as scanning downloaded files through integrated or third-party antivirus software. However, these methods have limitations:

[0046] 1. Response time: Local security checks are usually performed after the file is downloaded, which means that the malware has already entered the user's local system. Even if the threat is detected, there is a certain degree of difficulty in removal and potential residual risks.

[0047] 2. Security vulnerabilities: New malware continues to emerge, and the virus database updates of security software often lag behind the emergence of new threats, which provides malware with opportunities to take advantage.

[0048] 3. System resource usage: Security check software usually requires a lot of computing resources, which may affect system performance and user experience for devices with lower configurations.

[0049] 4. User dependence: Users need to rely on the effectiveness of security software and their own security awareness, both of which are often difficult to guarantee.

[0050] In order to solve the above technical problems, the file download method provided in the embodiment of the present application is based on the remote isolated secure browser (RBI) technology. The RBI technology creates an isolated browsing environment on the server side, and all the user's browsing activities including file downloads are performed in this isolated environment. This means that any potential malware is restricted to the remote server and cannot directly access the user's local system. In addition, RBI can also be combined with cloud security services to provide more timely and comprehensive security checks.

[0051] Therefore, an efficient and reliable remote isolation secure browser download function control system is particularly important. It can not only improve the security of users during web browsing and reduce the risk of malware intrusion, but also improve the user's browsing experience by reducing dependence on local resources. More importantly, for corporate users, this technology can help companies build a more solid network security line of defense and protect corporate information assets from network threats.

[0052] In summary, the download function control technology of the remote isolation security browser is not only crucial to the network security of individual users, but also has great significance for ensuring the security and stability of the entire network ecosystem.

[0053] To this end, the file download method in the present application can be applied to the application environment shown in Figure 1. The RBI front end 102 communicates with the back end 104 through a network. The back end 104 includes multiple distributed servers, and the distributed servers include an RBI manager, an RBI edge server, an RBI streaming client, a back end system, an RBI manager client, a storage server, and a message queue.

[0054] Among them, the user uses the RBI front end 102 to access the web page, and the back end 104 receives the download request sent by the RBI front end through the RBI manager, and the download request carries the identifier of the file to be downloaded; the file corresponding to the identifier of the file to be downloaded is downloaded through the RBI streaming client, and the information of the completion of the file download is sent to the RBI manager client; the file is uploaded to the file storage through the RBI manager client, and the file link generated by the file storage is obtained; the file link is returned to the RBI front end, and the file link is used by the RBI front end to download the file. In this way, the downloaded files are stored in the file storage, rather than locally in the RBI front end, which effectively isolates the potential security risks in the process of users accessing web pages and downloading files, protects the user's device from the influence of malware and network attacks, and improves security.

[0055] Among them, the RBI front end 102 can be installed in a terminal, which can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The backend 104 can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0056] In an exemplary embodiment, as shown in FIG. 2 , a file download method is provided, which is described by taking the method applied to the backend 104 in FIG. 1 as an example, and includes the following steps 202 to 208 . Among them:

[0057] S202: receiving a download request sent by the RBI front end through the RBI manager, where the download request carries an identifier of a file to be downloaded.

[0058] The RBI edge server transmits web page content to the RBI front end, and the user browses the web page through the RBI front end. The RBI edge server is used to ensure that the user can browse the web page content.

[0059] In this way, when the user clicks a download link on the web page of the RBI front end, the download request is sent to the RBI streaming client corresponding to the RBI edge server.

[0060] S204: Download the file corresponding to the to-be-downloaded file identifier through the RBI streaming client, and send information indicating that the file download is complete to the RBI manager client.

[0061] Among them, the RBI streaming client is used to download the file corresponding to the file identifier to be downloaded, so that the file is downloaded on the RBI streaming client instead of the RBI front end. By isolating the user's downloading activities on the server side, even if the file the user attempts to download contains malware, it will not pose a direct threat to the user's local computer system.

[0062] After the RBI streaming client completes downloading the file, it sends the file download completion information to the RBI manager client.

[0063] S206: Upload the file to the file storage through the RBI manager client, and obtain the file link generated by the file storage.

[0064] The downloaded file is uploaded to the file storage through the RBI manager client, where the file storage may be an S3 storage service. In other embodiments, the file storage may also be other storage services, which are not specifically limited here.

[0065] The file storage can generate corresponding file links for easy downloading by the RBI front end.

[0066] Optionally, the download link may be a temporary download link.

[0067] S208: Return the file link to the RBI front end, and the file link is used by the RBI front end to download the file.

[0068] The file storage returns the file link to the RBI front end, and the RBI front end displays the file link so that the RBI front end can download the file through the temporary download link.

[0069] The above-mentioned file download method receives a download request sent by the RBI front end through the RBI manager, and the download request carries an identifier of the file to be downloaded; downloads the file corresponding to the identifier of the file to be downloaded through the RBI streaming media client, and sends information on the completion of the file download to the RBI manager client; uploads the file to the file storage through the RBI manager client, and obtains the file link generated by the file storage; returns the file link to the RBI front end, and the file link is used by the RBI front end to download the file, so that the downloaded file is stored in the file storage rather than locally on the RBI front end, which effectively isolates the potential security risks in the process of users accessing web pages and downloading files, protects user devices from malware and network attacks, and improves security.

[0070] In one of the optional embodiments, before receiving the download request sent by the RBI front end, it includes: receiving the download process trigger instruction sent by the RBI front end; calling the initialization interface of the RBI manager to start the download process; determining the RBI edge server corresponding to the download process trigger instruction based on the load balancing strategy through the RBI manager, and establishing a connection between the edge server and the RBI front end; transmitting the web page content to the RBI front end through the edge server.

[0071] Among them, this embodiment mainly involves the initiation of the download process. The user visits a specific web page through a browser to trigger the download process. For example, when the user opens a link through a remote isolation security browser, the user's access request is first received by the RBI front-end, and the RBI front-end calls the initialization interface of the RBI manager to start the download process. Specifically, the start interface of the RBI manager (rbi-manager) is called to initialize the download process.

[0072] The RBI manager selects the appropriate RBI edge server (rbi-edge), establishes a connection between the RBI front end and the RBI edge server, and displays the web content that the user accesses through the RBI edge server.

[0073] The RBI manager selects a suitable RBI edge server based on the current load and other strategies. Specifically, the RBI manager can select the RBI edge server with the smallest load as the edge server for communicating with the RBI front end, thereby realizing communication between the RBI front end and the RBI edge server. In other embodiments, other strategies may also be adopted, such as priority strategies, etc., which are not specifically limited here.

[0074] The selected RBI edge server can transmit web page content to the RBI front end, and the user browses the web page at the RBI front end.

[0075] In the above embodiments, through the intelligent selection and deployment of the RBI edge server, the performance of user access and downloading can be optimized according to the real-time load and network conditions, and the response speed and stability can be improved.

[0076] In one of the optional embodiments, before downloading the file corresponding to the file identifier to be downloaded through the RBI streaming client, it also includes: performing an authority check on the download request through the RBI streaming client, and checking the file size corresponding to the file identifier to be downloaded; when the authority check passes and the file size corresponding to the file identifier to be downloaded is within a preset range, continuing to execute the step of downloading the file corresponding to the file identifier to be downloaded through the RBI streaming client.

[0077] Permission verification refers to whether the RBI front-end has the permission to download the corresponding file. The permission can be pre-set. For example, the account logged into the RBI front-end corresponds to different roles, and the permissions of different roles are different. After receiving the download request sent by the RBI front-end, the account logged into the RBI front-end can be verified for permissions, wherein the permission verification may include: obtaining the permission information corresponding to the account and the permission information corresponding to the file identifier to be downloaded, and determining whether the permission information corresponding to the account includes the permission information corresponding to the file identifier to be downloaded. If it does, it is determined that the RBI front-end has passed the permission verification, otherwise it is determined that the RBI front-end has not passed the permission verification. Optionally, the permission information corresponding to different file types may be different, so the permission information of the corresponding file can be configured based on the file type.

[0078] The file size check is to determine whether the file size corresponding to the file identifier to be downloaded is within the file size range corresponding to the account. If so, the file size check passes.

[0079] The file size range corresponding to the account can be pre-configured, which provides enterprises with flexible download control strategies, including but not limited to file size restrictions, file type filtering, etc., to meet the needs of different security levels.

[0080] Among them, the permission check and the file size check can be performed through a corresponding verification system, and the verification system can receive corresponding configuration information and enable the configuration information corresponding to the permission check and the file size check.

[0081] After receiving the download request, the RBI streaming client calls the verification system to verify the download request, including verifying the user's identity and checking whether he has the download permission. The verification system returns the permission verification result to the RBI streaming client. If the user does not have the download permission, the RBI streaming client passes the error information back to the RBI front end through the RBI manager, and the RBI front end displays the error prompt to the user. The verification system can be a module in the RBI manager, or a separate verification system, which is not specifically limited here.

[0082] After the permission check is passed, the RBI streaming client checks the file size. If the file size is not within the preset range, the RBI streaming client transmits the error information back to the RBI front end through the RBI manager, and the RBI front end displays the error prompt to the user. If it is within the preset range, the RBI streaming client downloads the file corresponding to the file identifier to be downloaded.

[0083] In some optional embodiments, downloading the file corresponding to the to-be-downloaded file identifier through the RBI streaming client includes: starting the download function in the container through the RBI streaming client to download the file corresponding to the to-be-downloaded file identifier. In this way, the in-container download technology effectively utilizes system resources, improves the download speed, optimizes the file transfer process, and reduces network congestion and transmission delay.

[0084] In the above embodiments, enterprises are provided with flexible download control policies, including but not limited to file size restrictions, file type filtering, etc., to meet the needs of different security levels. Permission verification and file checking ensure that only authorized users can download files, and limit the size of downloaded files, effectively preventing overly large files from having a negative impact on the system and user experience.

[0085] In one of the optional embodiments, obtaining a file link generated by a file storage includes: returning the generated file link to an RBI manager through the file storage, wherein the file link is a temporary download link with a validity period; sending the file link to a message queue through the RBI manager; notifying an RBI streaming client of the file link through the message queue; and returning the file link to an RBI front end through the RBI streaming client.

[0086] The file storage returns the file upload result to the RBI manager client. If the RBI streaming client successfully uploads the file to the file storage, the file storage continues to generate a temporary download link. For example, the file storage generates a temporary file link with a validity period of three minutes and returns the file link to the RBI manager. In other embodiments, the validity period of the file link can be other time periods, which are not specifically limited here.

[0087] The RBI manager passes the upload result and temporary download link to the RBI streaming client through the message queue. For example, the RBI manager passes the upload result and temporary download link to the message queue through the message queue, and the message queue passes the information to the RBI streaming client. The RBI streaming client transmits the received upload result and download link to the RBI front end. The RBI front end displays the corresponding results to the user based on the received information. If the download is successful, the user can download the file through the temporary download link; if it fails, the front end displays the corresponding error message.

[0088] In the above embodiment, the generation and management of temporary download links enable users to easily obtain and download the files they need without the need for complicated login and authorization processes, thereby simplifying the operation process; the use of message queues optimizes the information transmission and collaboration between modules within the system, so that upload results and download links can be efficiently transmitted and processed, thereby enhancing the manageability and scalability of the system.

[0089] In one of the optional embodiments, before obtaining the file link generated by the file storage, the method further includes: performing security processing on the file through the file storage.

[0090] After the file is uploaded to the file storage, the file storage can perform security processing on the file. For example, to prevent the downloaded file from containing a virus, the suffix .tmp is added to the .exe file. In this way, the security check of the file is placed in the file storage instead of the RBI front end, which can reduce the pressure on the front end.

[0091] Among them, different levels of processing can be used for the security processing of files to meet the needs of different security levels, and the processing strategies corresponding to different levels may be different.

[0092] The above embodiments implement real-time monitoring of downloading behaviors, timely interception and processing of potential security threats, thereby providing more proactive security protection, and reducing the enterprise's operation and maintenance costs in information security through centralized security management and automated security inspection processes.

[0093] For ease of understanding, FIG3 and FIG4 are combined, where FIG3 is a timing diagram of a file download method in an embodiment, and FIG4 is a network scene diagram of a file download method in an embodiment. In this embodiment, the downloading activities of users are isolated in the background to achieve real-time monitoring and control of downloading behaviors, thereby improving the security of downloading activities. The following is a detailed technical solution:

[0094] Start the download process: When the user opens the link through the remote isolation secure browser (RBI front-end), the RBI manager (rbi-manager) calls its start interface to initialize the download process.

[0095] Select RBI edge server: RBI manager selects the appropriate RBI edge server (rbi-edge), establishes the connection between RBI front end and RBI edge server, and displays the web content that users access through RBI edge server.

[0096] Download request interception: When a user clicks the download operation on a web page, the RBI streaming client (rbi-streaming-client) intercepts the download request and handles the Browser.downloadWillBegin and Browser.downloadProgress events in the ChromeDevToolsProtocol (CDP).

[0097] Download permission verification: The background checks whether the user has download permission. If the download permission is not enabled, an error message is returned and displayed to the user by the RBI front end.

[0098] File size limit: The backend determines the size of the file to be downloaded. If it exceeds the preset `download_max_size` limit, an error message is returned and displayed to the user by the RBI frontend.

[0099] Start downloading in the container: The RBI streaming client starts the Chrome download function in the container and downloads the file to the container.

[0100] Download completion notification: After the download is completed, the RBI streaming client notifies the RBI manager client (rbi-manager-client) through the message queue that the download is complete.

[0101] Upload the file to the file storage S3: After the file is downloaded, the key value of the file storage S3 storage service is generated through the label, and the file is uploaded to the file storage S3. To prevent the downloaded file from containing viruses, add the suffix .tmp to the .exe file.

[0102] Upload result processing: The system returns the result of uploading the file to the file storage S3. If the upload is successful, the next step will be carried out. If the upload fails, the system will jump to the error handling step.

[0103] Generate a temporary download link: Call the file storage S3 service to generate a temporary download link that is valid for three minutes.

[0104] Return download link: Return the generated temporary download link to the RBI manager.

[0105] File review and virus detection: Review and detect viruses on downloaded files.

[0106] Message queue transmission information: Based on the upload result processing, the return download link, and the file review and detection results, the upload file storage S3 results, review detection information, and temporary download link are transmitted to the RBI streaming client through the message queue.

[0107] Front-end data transmission: Information is transmitted to the RBI front-end through the data channel.

[0108] Front-end display results: According to the message queue transmission information, the RBI front-end displays the corresponding error information or starts the download task. For successful cases, the RBI front-end starts downloading the file in the file storage S3 through the temporary download link.

[0109] This application provides a systematic method to ensure that download activities in a remote isolated secure browser are fully securely controlled and supervised, thereby improving overall network security.

[0110] The above embodiments include at least the following significant effects:
