Active anti-intrusion big data network security device and anti-intrusion method

Abstract

The invention discloses an active anti-intrusion big data network security device, which is characterized by comprising a network interface server and a plurality of storage servers, one or more storage servers are public information storage servers (1), and the rest storage servers are private information storage servers (2); and the network interface server comprises a node permission auditing module (4), a data request auditing module (5), a private data weight calculation processor (6), an access link switch control group and a plurality of access request interface ends (3). According to the technical scheme, when the user data end is accessed, the request permission of the user data end and the privacy level of the requested privacy data are audited as much as possible, and whether the permission of the user data end conforms to the request data or not is determined; and when the storage server sends data to the user data ends, the data types and the data paths are audited, so that the user data ends with insufficient permission are prevented from obtaining the data.

Description

technical field [0001] The invention relates to an active anti-intrusion big data network security device and an anti-intrusion method, belonging to the field of network data security. Background technique [0002] With the emergence of cloud computing (Cloud Computing), the application of computer networks has undergone great changes. Through the cloud computing system, even if the calculation is very complicated, as long as the local computer sends a demand information to the remote cloud computing system through the Internet, The cloud computing system will complete the required calculations and return the results to the local computer. In this way, the local computer hardly needs any computing power, and all processing can be done by the remote cloud computing system, which moves the computing pressure from the local computer to the remote cloud computing system. The data security gateway system is a necessary device for cloud computing. The security gateway supports tw...

Problems solved by technology

[0006] In the existing technology, private files are generally stored in an encrypted form. When the network security gateway accesses the gateway device at the user data end, it does not set too high restrictions on the access to private data, and neither the data request nor the data transmission of the user data end is performed. Detailed inspection, if the private data is decrypted after leakage, it may cause the content of the private data to leak, affecting the security of the private data
