Problems solved by technology

Although AWStats has certain characteristics in the analysis of web logs, there are still great defects in the processing mechanism: AWStats solidifies the analysis function of each log file in the tool according to the characteristics of each log file, so This tool can only realize the automatic analysis of several specific web log files. For other types of log files, the functional expansion can only be realized by changing the original program. This mechanism makes AWStats unable to meet the requirements at all. The log analysis function of various types of systems, servers or security devices has great limitations in its application range

Embodiment 1

[0122] Embodiment 1: Information automatic extraction and analysis process of Skynet Firewall log files.

[0123] Skynet firewall log files are of text type, and the logs to be analyzed are as follows:

[0124] [1:59:58] Port 1294 of 192.168.0.107 stops sending data to this machine,

[0125] TCP flag: FA

[0126] continue to next rule

[0127] [1:59:58] The machine answers port 1294 of 192.168.0.107,

[0128] TCP flag: A

[0129] continue to next rule

[0130] [1:59:58] The Http[80] port of this machine stops sending data to 192.168.0.107,

[0131] TCP flag: FA

[0132] continue to next rule

[0133] The automatic extraction and analysis process of the Skynet Firewall log file information is as follows:

[0134] (1) Define the log analysis template

[0135] From the above information, it can be seen that the log file includes three types of records, from the first line to the third line is the record that the remote host port stops sending data to the local machine, and...

Abstract

A method for picking up and analysing information automatically includes using XML daily record analysing module to enter automatic picking up procedure, compairing packed up daily record with safety rule to judge whether system operation is abnormal or not, recording biased byte value of each analysis, detecting variation of each target device or daily record file at fixed time to realize automatic analysis to increased part of daily record according to recorded state information of dialy record.

Description

technical field [0001] The invention relates to a method for automatic extraction and analysis of log information, in particular to a method for automatic extraction and analysis of heterogeneous log information based on a template, which belongs to the field of information technology. Background technique [0002] At present, various hosts, servers, network devices, security devices, operating systems, and application systems all have logging functions to record the operating status and usage of the devices and systems themselves. It is a common practice to establish a network-wide audit and monitoring system to collect, manage and analyze all kinds of log information. Although log files contain a wealth of valuable information, the information is only useful if you dig deeper. Judging from the current implementation situation, most systems focus on the collection of log information, and the ability to analyze logs is relatively weak. Usually, in the case of serious securi...
