  • Publication number: 20220272111
    Abstract: In one aspect, a method for implementing a cloud-platform push for one or more known data breaches includes the step of, for each data breach of the one or more known data breaches, providing a functionality that maps one or more kill chains or Tactics, Techniques, and Procedures (TTPs) for a specified set of security dimensions. A step includes generating a security rule for each mapped kill chain or TTP based on the functionality that maps the one or more kill chains or Tactics, Techniques, and Procedures (TTPs) for a specified set of security dimensions. A step includes pushing the security rule to an enterprise so that the enterprise is aware of a vulnerability in the data breach. A step includes generating a customized posture for a Virtual private cloud (VPC) in the enterprise's cloud-based network. A step includes determining that the data breach can occur within the enterprise's cloud-based network.

  • Publication number: 20210304900
    Abstract: A method and apparatus for predicting transmission of an infectious disease, a computer apparatus, and a storage medium. The method includes determining one or more objects to be predicted, matching in a historical travel path database for a corresponding predicted path of each of the one or more objects to be predicted, and determining a transmission trend of the infectious disease in the one or more objects to be predicted based on the predicted travel paths. The predicted travel path of each object to be predicted is matched in the historical travel path database thus achieving the effect of reducing the computation amount of obtaining the predicted travel path.

  • Patent number: 10770251
    Abstract: An alternating current contactor comprises a base and a magnetic yoke. The magnetic yoke is mounted on a bottom plate of the base. A magnetic yoke support for supporting and buffering the magnetic yoke is respectively provided at two sides of the magnetic yoke, wherein sidewalls at two sides of each magnetic yoke support, which are connected with the magnetic yoke are different in thickness. The magnetic yoke support of the alternating current contactor of the utility model has a simple structure due to the arrangement of an asymmetric eccentric structure. The up-down position of the magnetic yoke relative to the bottom plate of the base can be adjusted by changing an assembly direction of the magnetic yoke supports, thereby achieving the purpose of adjusting the total stroke of the product with high flexibility.
