A Network Data Analysis Method Based on Application Layer Data

Abstract

The invention discloses a network data analysis method based on application layer data, which includes the following steps: screening out the application layer: capturing and reading network data through Next Generation Firewalls, NGFW, using a recognition engine to load and analyze current data packet information, and judging whether Contains application layer data packets. If it is an application layer data packet, use the recognition engine to load and analyze the application layer data of each application layer data packet; analyze the application layer: use Next Generation Firewalls, NGFW to filter the selected application layer data , to obtain application layer data that meets the requirements; the present invention uses Next Generation Firewalls, NGFW to capture and read network data, Next Generation Firewalls, NGFW is a new generation technology, can break through the encryption of the existing data surface, and can effectively capture and read network data In order to reduce the failure rate of network data analysis, cluster analysis will be performed during the analysis process, and then the application layer data will be analyzed in detail according to the needs.

Description

technical field [0001] The invention relates to the technical field of network data, in particular to a network data analysis method based on application layer data. Background technique [0002] Network data is divided into four layers: application layer, transport layer, network layer and link layer. At present, the network analysis software widely used in the industry includes Wireshark, Sniffer, etc., but the current network data analysis method captures and reads network data. Most of them are based on traditional related software. In order to enhance data security, network data is encapsulated and encrypted, which leads to a high failure rate and error-prone use of traditional network data analysis methods. In addition, the data is not classified, resulting in mixed results of analysis, which easily leads to data confusion. Therefore, a network data analysis method based on application layer data is proposed to solve this problem. Contents of the invention [0003]...
