Embodiment Construction

[0039] Such as figure 1 As shown, the implementation steps of the web log online tracking method based on feature retrieval in this embodiment include:

[0040] 1) Real-time capture of network traffic mirroring packets;

[0041] 2) Receive the filter parameter array from the control center K [ M ] and the time threshold t , the length of the network traffic mirroring data packet is the time threshold t An array of network packets according to filter parameters K [ M ] Recorded network behavior parameters are filtered based on the filter model of the hash table of network behavior characteristic attributes to obtain network log files of attack behaviors;

[0042] 3) Output the network log files to the control center in the way of resuming upload from breakpoints.

[0043] Such as figure 2 As shown, the basic program modules of the network log online tracking method based on feature retrieval in this embodiment include a traffic data collection module, a traffic data f...

Abstract

The invention discloses a network log online tracking method and system based on feature retrieval, the on-line tracing method of the network log of the invention comprises the following steps of: real-time capturing a network traffic mirror data packet, receiving an array of filter parameters K [M] from the control center and a sum time threshold t, according to the network behavior parameter recorded by the filter parameter array K [M] and based on the filter model of the hash table of the network behavior characteristic attribute, the network data packet with the length of the time threshold t in the network traffic mirror packet is filtered, obtaining the attack behavior of the network log file, the network log file by the way of breakpoint renewal output to the control center. The invention can quickly screen qualified flow data, realize on-line retrieval and tracking of massive flow data, output network log files to a control center in a break-point renewal mode, and transmit data in real time and reliably.

Description

technical field [0001] The invention relates to a real-time online tracking technology of network logs in network security, in particular to a method and system for online tracking of network logs based on feature retrieval. Background technique [0002] With the continuous development of information technology, information systems and facilities provide great convenience for the production and life of all walks of life, and the related network security has become a key link related to public security and even national security. Real-time monitoring of attacks and illegal behaviors has become a necessary measure to protect the security of critical information infrastructure. [0003] In order to accurately verify and deeply analyze attack behaviors, it is necessary to track suspicious access behaviors in real time and discover their attack intentions and targets in time. The access behavior of the information system is recorded in the network traffic data, including the sou...
