  • Publication number: 20210234871
    Abstract: Provided is an infection-spreading attack detection system and method, as well as a program enabling an occurrence of an infection-spreading attack to be detected with high accuracy. A first feature amount is calculated based on traffic information on a packet transferred by a transfer device, and M partial address space(s) are identified to be a monitoring target based on the first feature amount. A second feature amount is calculated for each of the M partial address space(s) based on the traffic information related to the M partial address space(s). Abnormality detection determination is performed on each of the M partial address space(s) based on the second feature amount. Whether the infection-spreading attack has occurred is determined by evaluating M determination results.

  • Patent number: 10544425
    Abstract: By a QTL analysis and so forth using 4-HPPD inhibitor-susceptible rice and 4-HPPD inhibitor-resistant rice, a hypothetical gene (HIS1 gene) of an iron/ascorbate-dependent oxidoreductase gene located on a short arm of chromosome 2 of rice has been identified as a 4-HPPD inhibitor-resistance gene. Further, it has also been revealed that a homologous gene (HSL1 gene) of the HIS1 gene is located on chromosome 6 of rice. Furthermore, it has been found out that utilizations of these genes make it possible to efficiently produce a plant having increased resistance or susceptibility to a 4-HPPD inhibitor and to efficiently determine whether a plant has resistance or susceptibility to a 4-HPPD inhibitor.
