  • Patent number: 11170133
    Abstract: The present invention discloses an external terminal protection device for data flow control and a corresponding protection system. The external terminal protection device includes: an interface control module, used for providing a plurality of data interfaces respectively connected to a protected host and one or more external devices; and a system control module, used for monitoring in real time a data transmission state of each data interface in the interface control module, and controlling the data flow of each data interface. The present invention realizes the functions of performing protocol filtering and auditing on various types of data flow without installing flow monitoring and security protection software on the protected host, and achieves the effects of low-latency network auditing and high-reliability protocol filtering, thereby comprehensively eliminating potential security hazards such as Trojan Horse virus implantation and flow anomaly that may be generated by the interfaces.

  • Patent number: 10885230
    Abstract: The present invention provides an external terminal protection device and a corresponding protection system, the external terminal protection device including: an interface control module, used for providing an internal interface and an external interface, the internal interface being connected to a corresponding interface of a protected host, and the external interface being configured to access one or more external devices; and a system control module, used for connecting the interface control module, and controlling security authentication of the external devices accessed to the one or more external interfaces on the interface control module, so as to determine whether the external devices are licensed access devices. The present invention can protect the security of the protected host without installing security protection software on the protected host, thereby greatly reducing system security risks, and comprehensively eliminating the potential security hazards that may be generated by the interfaces.

  • Patent number: 10757037
    Abstract: A method and system for dynamic scheduling and allocation of network traffic are provided. The method includes: distributing, by a central scheduling system, a domain name initial configuration table and a determination strategy to each detection node; detecting, by each detection node, each server node of a pre-set domain name in the domain name initial configuration table, thereby obtaining performance information of each server node; generating, by each detection node, a corresponding best coverage record; and converting, by the central scheduling system, the best coverage record into a target server node and feeding back, by the central scheduling system, the target server node to a local DNS server. The disclosed method and system for dynamic scheduling and allocation of network traffic improves network access speed and reduces operation and maintenance cost.
