Embodiment Construction

[0033] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] First of all, the database audit method under the load of large data flow includes environment detection, data flow collection and distribution, content analysis, and audit response; data packet content analysis includes analysis algorithms based on finite state machines, such as figure 1 Shown:

[0035] After getting the data packet from the network card, take out the database port by offset, confirm whether the protocol of the port needs to be audited, if not, discard it directly, and place the data packet on the ring queue if necessary;

[0036] Get the data packet from the ring queue, offset the five-tuple information and application layer data;

[0037] Call the public plug-in to match the host of the data packet, confirm whether the data flow of the business host needs to be audited, if not, discard it directly, and continue to...

Abstract

The invention aims to provide a database high-efficiency auditing method, system and equipment for a big data stream load, various network messages are quickly classified through a finite-state machine processing mechanism, so that the message preprocessing stream is simplified, and full utilization of system resources is realized; by integrating the optimized Hash algorithm, the annular queue andthe large page cache, the large data flow obtained by the network card can be dynamically distributed to a plurality of engines for processing, so that the data packet processing performance is greatly improved; control and data processing are separated, so that scheduling among multiple engine threads is reduced, and the processing efficiency is improved; regular matching, binary comparison, accurate data analysis and other methods are adopted, and auditing of mainstream databases at home and abroad and SSL encrypted databases is achieved.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a database audit method for realizing adaptability and high-efficiency audit under the load of large data flow, and a database audit system and equipment applying the method. Background technique [0002] With the continuous acceleration of global informatization, the application of information technology is becoming more and more extensive, especially the rise of mobile Internet, social media, and e-commerce, which has generated massive amounts of data. As the basis of information, databases carry more and more Business-critical systems have gradually become important assets in business and public security. Once tampered with or leaked, it will cause economic losses to the company or society at the slightest, and affect the image of the company or even social security at the worst. In reality, database information assets are facing severe security threats: o...
