  • Patent number: 11252184
    Abstract: An anti-attack data transmission method and an apparatus thereof are provided. The method includes obtaining a communication protocol message to be transmitted; performing an anti-attack pre-processing for data on information bit(s) located at a message header in the communication protocol message, and generating processing information; storing the processing information in extension bit(s) at the message header of the communication protocol message to obtain a converted communication protocol message, wherein the message header of the communication protocol message includes the information bit(s) and the extension bit(s); and sending the converted communication protocol message to a receiving device. The present disclosure solves the problem of false negatives associated with normally transmitted data flow caused by existing anti-attack methods.

  • Patent number: 11102240
    Abstract: Early-warning decision method, node and system are provided in the present disclosure. The method includes obtaining a flow analysis result of a portion of service requests that are targeted at a same server; calculating a flow of all the service requests that are targeted at the server based on a flow indicated by the flow analysis result and a weight of a current distributed node, the weight being a weight or proportion of all the service requests targeted at the server that accounts for the flow indicated by the flow analysis result that is obtained by the current distributed node; comparing a flow of all the service requests that are targeted at the server with an abnormal flow threshold; and determining whether to send an instruction for performing subsequent processing on the server based on a comparison result.

  • Publication number: 20190319923
    Abstract: A network data control method, system and security protection device, the method comprising the steps of: receiving flow characteristic information reported by a firewall; analyzing the flow characteristic information or the network behavior information determined by the flow characteristic information to obtain an analysis result; and on the basis of the analysis result, determining the control instruction to be sent to the firewall, wherein the control instruction is used to control network data passing through the firewall. Advantageously, the present invention addresses a prior art problem in firewall poor performance in protecting network data.
