摘要： A method of updating intrusion detection rules through a link data packet is used to dynamically update rules storages of Snort system hosts. Firstly, an update sponsor in the network transmits a link data packet with an intrusion detection rule to the Snort system host. The Snort system host acquires the intrusion detection rule from the received link data packet, and parses an operation type of the intrusion detection rule. Then, the Snort system host verifies the validity of the intrusion detection rule. Subsequently, the rules storage is updated according to the type of the valid intrusion detection rule and a rules tree.

摘要： A file data restoring system and method of a computer operating system and software thereof are applied in the installation of an operating system into a client computer. Divide the file data corresponding to the operating system into data blocks according to an appointed data size. Generate a check code for each of the data blocks to form a sequence list of original check codes and a sequence list of target check codes. Compare the sequence list of original check codes with the sequence list of target check codes, after installing the operating system into the computer. If the comparison result is inconsistent, a restoring call information is sent out. The position of the inconsistent check code is acquired through the restoring call information and the comparison result. The original file data corresponding to the position of the check code is read and restored to a corresponding target file.

摘要： A method for verifying refreshed BIOS content includes the following steps. A virtual machine (VM) is established in a computer waiting for a system BIOS update by the use of a paravirtualization technique. The VM is booted. A new BIOS file content is copied to an address space in a designated range of a memory of a computer host. The computer host is booted with the content of the new BIOS file, and the paravirtual operating system runs on the same hardware platform of the computer host. And, whether the virtual operating system adopting the new BIOS file content runs normally or not is verified to confirm the correctness and safety of the content of the new BIOS file.

摘要： An asynchronous request-response communication method is applied in data transmission for applications running in a server. The asynchronous request-response method includes the following steps. Establish a socket and a connection port corresponding to a request in a request side; set an object pool in each request side respectively, for recording connection statuses of the sockets corresponding to different requests; wait till the server has finished the request; once the server has finished the received request, the server transmits a callback message to the corresponding socket of the request side; and search a corresponding process event in the object pool according to the callback message. The request side adopts the socket and the connection port to perform the asynchronous request-response operations, thereby reducing the connection load between the server and the request side.

摘要： A network intrusion detection system (IDS) is built at an important network node and used to detect and monitor network packets. The network intrusion detection system includes a network card and a system core processor. When receiving a network packet, a micro-processor of the network card performs a packet decode procedure and a packet preprocess procedure, thereby verifying a type and a source address of the packet in advance and converting the packet into an IDS format packet. Afterwards, the system core processor determines whether the packet is an intrusion packet. Since the computation of the packet decode procedure and the packet pre-process procedure is handled by the network card, the network intrusion detection system will not lose packets due to too heavy computation burden, thereby greatly improving the accuracy of the network intrusion detection system.

摘要： A system and a method of processing sender requests for remote replication are applied in local system having a plurality of network block devices (NBD). A fixed number of sender threads are created in local system to form sender thread pool. All NBDs receiving write request for corresponding remote mirror volume are serially connected to be circular linked list. A pointer is set to sequentially record latest processed NBD in circular linked list, the sender threads in the sender thread pool are allocated to actively search NBD to be processed pointed by the pointer according to a sequence in circular linked list, and processing of NBD pointed by the pointer is locked by using the sender thread, hence processing the sender request of NBD. Each time when the sender request is finished, the pointer is sequentially moved to next NBD and the sender request of corresponding NBD is performed.

摘要： A system and method for updating dirty data of designated raw device is applied in Linux system. A format of a command parameter for updating the dirty data of the designated raw device is determined, to obtain the command parameter with the correct format and transmit it into the Kernel of the Linux system. Then, a data structure of the designated raw device is sought based on the command parameter, to obtain a fast search tree of the designated raw device. Finally, all dirty data pages of the designated raw device are found by the fast search tree, and then are updated into a magnetic disk in a synchronous or asynchronous manner. Therefore, the dirty data of an individual raw device can be updated and written into the magnetic disk without interrupting the normal operation of the system, hereby ensuring secure, convenient, and highly efficient update of the dirty data.
