Hierarchical aggregation management system for multi-source heterogeneous security data

Abstract

The invention relates to the technical field of data management, and particularly discloses a multi-source heterogeneous security data hierarchical aggregation management system which comprises a data extraction module used for extracting original data fragments. And the key data acquisition module is used for identifying the original data fragments and obtaining fragment numbers. And the data aggregation module fuses the original data fragment and the fragment number to obtain a fusion code. And the coding module is used for recombining the fusion code to obtain a combined code. And the data transmission module is used for transmitting the combination code. And the reverse order decoding module is used for carrying out inverse operation on the combined code to obtain a restored fusion code. And the data comparison module is used for restoring the restored fusion code to obtain an original data fragment. And the data fusion module is used for associating the restored original data fragments with the multi-source data and selecting data from top to bottom for data aggregation. According to the method, the fusion code is formed by the original data fragments and is transmitted through the combination code, so that the concealment is high and the secrecy capability is strong.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a multi-source heterogeneous security data hierarchical aggregation management system. Background technique [0002] With the development of science and technology and the progress of society, human beings have entered the era of digitalization. Multiple sources refer to multiple data holders, while heterogeneity refers to inconsistent data types and characteristics. With the continuous promotion and use of the network, its scale is becoming larger and larger, and intrusion attacks are also developing in the direction of scale, complexity and intelligence, which brings more and more threats to the network and causes more and more losses. bigger. In this situation, a defense-in-depth system based on a series of security devices such as intrusion detection, firewall, and anti-virus system has been established, but new problems have also emerged: the intrusion detection sy...

Problems solved by technology

In this situation, a defense-in-depth system based on a series of security devices such as intrusion detection, firewall, and anti-virus system has been established, but new problems have also emerged: the intrusion detection system itself has a high rate of false alarms and false negatives. At the same time, with the continuous increase of security systems, various alarm information and logs have increased by orders of magnitude, making it difficult for security administrators to understand the security threats of the system and take effective response measures in a timely manner in the face of such a large amount of information. Existing data transmission takes up a lot of traffic and has poor security
