A processing device writes file system data to a first area of a memory zone of a zoned block memory device based on a current position of a write pointer within the memory zone. The file system data comprises data files contained within a file system and file structure metadata describing a file structure of the file system. The processing device detects a write event based on the write pointer advancing past a predetermined memory address within the memory zone that corresponds to a checkpoint. The checkpoint is a second area within the memory zone that is designated for storing write event data. Based on detecting the write event, the processing device writes write event data to the checkpoint, the first write event data indicating a most recent memory address of a root node of the file structure within the memory zone.

This disclosure provides a reverse DNS resolution method, apparatus, device, medium, and product. The reverse DNS resolution method includes: responding to a reverse DNS resolution request sent by a terminal, detecting the operational status of the local reverse DNS resolution link; and determining whether to import reverse DNS resolution records from a local Zone file based on the operational status. These reverse DNS resolution records are used to provide reverse DNS resolution services to the terminal. Through the embodiments of this disclosure, the reliability of the reverse DNS resolution scheme can be improved. Even in extreme cases such as interruptions to the domain root, top-level domain, and authoritative services, reverse DNS resolution services can still be provided to the terminal. Under the premise that the Local DNS does not require administrator configuration or need to maintain a network connection with the protection platform, reverse DNS resolution protection can be adaptively implemented based on existing DNS protection snapshots.

The invention discloses a secure exchange method and system for multi-area files, and the method comprises the steps: receiving a file exchange instruction sent by a user terminal in a local area network, the file exchange instruction comprising a to-be-transmitted file, a target transmission engine node B, and a target user terminal and / or a target storage position; performing security check on the to-be-transmitted file according to a preset security policy; if the file to be transmitted passes the security check, interacting with the user terminal and the target transmission engine node B according to a preset maximum transmission thread confirmation strategy to obtain the maximum transmission data packet length; according to the maximum transmission data packet length, performing virtual blocking or virtual splicing on the to-be-transmitted file to obtain a plurality of to-be-transmitted data packets; and sending all the data packets to be transmitted to a target transmission engine node B, and enabling the target transmission engine node B to restore the received data packets and deliver the data packets to a target user terminal and / or a target storage position. According to the invention, the transmission efficiency and the transmission stability can be effectively improved, and the transmission safety can be improved.

The application provides a DNS domain name processing method, device, system, equipment and medium, wherein the method comprises: in response to a DNS domain name processing request, displaying a domain name update window on a visual interface of a front end, the domain name update window being used for configuring domain name information; in response to an operation result of the domain name update window, obtaining a target domain name, a target domain name resolution address and a target domain name resolution server; generating domain name update information based on the target domain name, the target domain name resolution address and the target domain name resolution server, and generating an update code file based on the domain name update information; and transmitting the update code file to a back end, so that the back end updates a DNS domain name based on the update code file after backing up a current domain name zone file. Through the above method, automatic domain name update processing can be realized, the domain name update efficiency is effectively improved, and the domain name update error rate is reduced.

Using a block-based region file to extend a composite image (CIM). A device determines to replace a first file with a second file within a filesystem volume of the CIM. The device identifies a first file definition within CIM metadata, which defines the first data of the first file as including a first data block of a first CIM region file comprising equally-sized data blocks. The device extends the CIM to include the second file. The extension includes adding a second region file comprising equally-sized data blocks to the CIM, including writing a portion of data from the second file into a second data block of the second region file. The extension also includes writing a second file definition to the CIM metadata, which defines the second data of the second file as including the first data block and the second data block.

The invention discloses a security-critical software spatial visualization method and system. The method comprises the steps of analyzing and compiling a mapping file to obtain information, mapping a storage area, carrying out spatial statistics and classification, and carrying out visualization and output. The system comprises an analysis module, a storage module, a statistics module and a visualization module. According to the method, high-precision spatial distribution is achieved, and overall and subdivision statistics of the Flash, the internal RAM and the external RAM are covered with the obvious space; the multi-level display can refine space occupation analysis to a three-level structure of storage area-file-segment, supports accurate positioning of an optimization target, supports mapping file formats of various compilers, and improves reliability and safety of software.

This invention provides a DNS system root zone file trustworthiness association verification system based on multi-source heterogeneous data. It includes a multi-source heterogeneous data acquisition module, which is connected to an IANA Root Zone Database data acquisition module, an AXFR transfer data acquisition module, and an active probe data module. This system solves the technical problem that previous methods of acquiring root zone file data were often single-source, relying solely on DNS requests or zone transfer requests. However, these methods could not determine whether the acquired file was the latest version or whether it had been hijacked and tampered with. This invention allows for the dynamic construction of trustworthy root zone file data and enables dynamic monitoring of root zone files. The constructed trustworthy root zone file can be used to establish local roots, optimize the DNS resolution process, improve resolution efficiency, and also for detecting root-side resolution anomalies.
