Embodiment Construction
[0026] The technical solutions and beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0027] The present invention provides a system for realizing keyword pair matching, including:
[0028] A data acquisition module, configured to obtain keyword pair rules from a web server;
[0029] The data analysis module is used to match the data packet (text) with the rules, return the result set, and analyze whether it is intruded (triggered by keyword matching) according to the result set.
[0030] Such as figure 1 As shown, the present invention provides a kind of method that realizes keyword pair matching, comprises the steps:
[0031] Step 1, the web server acquires the rules in the form of defined keyword pairs and stores them in the database, wherein the rules are already configured in the policy;
[0032] Step 2, split the rule in the form of a keyword pair in step 1 into a single keyword (sub-rule) and...

The invention discloses a system for matching keyword pairs. The system comprises a data acquisition module which acquires a keyword pair rule from a web server and a data analyzing module which matches a data packet with the rule, returns a result set, and analyzes whether triggering is matched or not according to a result set. The invention also discloses a method for matching the keyword pairs. The method comprises the following steps: S1, acquiring a rule of a defined keyword pair form by the web server and storing the keyword pairs in a database; S2, splitting the rule into single keywords and separation distances; S3, matching the content of the data packet word by word with the single keywords to judge whether the content of the data packet is a character or not to obtain the number of characters of the tail ends of the keywords matched in a text as well as the positions of the keywords in the text, and storing the result in the result set; and S4, judging whether the separation distances are defined in a separation distance range of the defined rule or not, if so, match triggering is shown, and recording the result. According to the technical scheme, a plurality of keywords can be matched.
Description
technical field [0001] The invention belongs to the technical field of network protection, and in particular relates to a system and method for realizing keyword pair matching. Background technique [0002] A common network attack method is to include a specific attack code in the command. The basic principle of the existing algorithm is to match the processed data packet ("text") with the defined rules to search and judge whether there is an intrusion. The matching method is to match all rules at once (single keyword match). [0003] The existing rule matching method is to match all the rules at one time (single keyword match), which cannot achieve keyword pair (multiple keywords) matching, which needs to be improved. Contents of the invention [0004] The purpose of the present invention is to provide a system and method for matching keywords, which can match multiple keywords. [0005] In order to achieve the above object, the solution of the present invention is: ...
