Fecha de publicación: 03/09/2014 Fuente: Wipo "IOT" The invention provides an IOT (Internet of Things) security risk distributed evaluation method. According to the method, an IOT gateway, a computer network, a local IOT security threat detection module, a local IOT security risk calculation module, an IOT integral security risk calculation module, an IOT security threat feature library, an IOT security threat perniciousness library and an IOT asset value library are used. The IOT security risk distributed evaluation method comprises the following steps that: the local IOT security threat is detected; a local IOT security thread detector is subjected to attenuation; the local IOT security risk is calculated; and the IOT integral security risk is calculated. The method has the advantages that a distributed IOT security threat detection and local security risk calculation method is adopted; in addition, the dynamic change of the IOT security threat is tracked, and meanwhile, the IOT security threat perniciousness and the IOT asset value are combined for quantificationally calculating the IOT faced security risk value; the large-scale IOT security data can be effectively analyzed; and in addition, the IOT security risk can be quantificationally calculated.
