Information security defense system based on big data

Abstract

The invention discloses an information security defense system based on big data in the technical field of information security defense. The system comprises data acquisition, data processing, a database, a server and a user side, and is characterized in that the data acquired by the data is stored in the database after being processed, the database is connected with the server, and the user sideobtains data from the database or uploads the data through the server; the database comprises a risk monitoring module, a risk analysis module and a risk evaluation module, and the risk monitoring module, the risk analysis module and the risk evaluation module are used for monitoring and analyzing data signals transmitted by the downlink of the database, so that a user can clearly know the security of the data, the user can be effectively prompted and data exception entries can be known, whether exceptional data is deleted and shielded or not can be selected, good controllable security is achieved, and the security defensiveness of information under big data can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of information security defense, in particular to an information security defense system based on big data. Background technique [0002] Big data refers to a collection of data that cannot be captured, managed, and processed by conventional software tools within a certain period of time. It is a massive, Due to the high growth rate and diversified information assets, the traditional information security protection system adopts firewall technology and intrusion detection technology, which can no longer prevent deep attacks on the application layer, and cannot realize real-time blocking of attacks. Therefore, in order to ensure For the effective security of the network, the intrusion prevention system came into being. The intrusion prevention system checks the data packet byte by byte to prevent the attack behavior between the data link layer and the application layer. When a new attack method is discovered,...

Problems solved by technology

[0004] The purpose of the present invention is to provide an information security defense system based on big data, so as to solve the problem in the above-mentioned background technology that when data abnormality is found, the user cannot be properly prompted for security, so the user cannot timely understand the data situation and category. And it does not have the function of shielding and deleting, and there is a large hidden danger of information defense
