Data collaborative acquisition method and system

Abstract

The embodiment of the invention provides a data collaborative acquisition method and system. The method includes the following steps of: sending a collaborative acquisition request to each neighbor node in a collaborative neighbor node candidate set; generating a collaborative acquisition negotiation result based on the received collaborative acquisition feedback sent by all neighbor nodes that judge the data acquisition; and sending the collaborative acquisition negotiation result to each neighbor node in the collaborative acquisition neighbor node set to ensure that the neighbor nodes carryout data collaborative acquisition according to the collaborative acquisition negotiation result. The method and the system provided by the embodiment of the invention can maximize the global acquisition utility in a negotiation manner according to potential threats and/or acquisition tasks, further adjust the local acquisition strategy in real time, reduce computing resources, storage resources and transmission resources consumed by comprehensive data acquisition, and provide accurate data sources for safety monitoring and threat discovery.

[0003] The network environment of a large-scale heterogeneous Internet network is complex, with different security goals in different regions and at different times, and security threats are instantaneous and changeable with a wide range of threats. Collaborative collection and collaborative transmission of the key nodes of the network, the existing technology lacks the need to customize different collection strategies for each collection agent, resulting in low efficiency of threat detection in formulating and executing collection tasks, and the phenomenon of collection redundancy; at the same time, In a large-scale heterogeneous Internet network, when the collection agent performs the collection task and transmits the collection data, due to the large number of collection agents collecting various devices and systems and scattered locations, the centralized collection management module usually cannot be integrated with each collection agent. Agents communicate in real time. For example, in the current space-ground integrated information network, the acquisition management module is usually located on the ground, and the acquisition strategy is transmitted to the satellite through the gateway station, and then forwarded by the satellite to the acquisition agent on the terminal. Due to the high-speed movement of the satellite, The acquisition management module cannot coordinate the acquisition content and transmission content among acquisition agents through satellites at any time, resulting in repeated acquisition and transmission of the same data by multiple acquisition agents, resulting in a waste of computing resources, storage resources, and transmission resources
