Embodiment Construction
[0033] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0034] In most scenarios, the transmitted data packets adopt public general protocols, and the data packets can be parsed according to known protocols. However, in other scenarios, the transmitted data packets may use an unknown protocol, such as a custom protocol. In the prior art, the data packets using the unknown protocol cannot be parsed. In database audit products, when some databases are used, the relevant protocols of this type of database cannot be known, so the data packets transmitted with the database cannot be analyzed, and the database security audit is actually useless. Youxuan Database (UXDB) is a typical domestic database, and the existing technology cannot realize effective parsing of its result set. Therefore, the present invention provides a targeted query result set parsing method.

The invention discloses a method for analyzing a query result set of a dazzling database, which comprises the following steps: filtering according to a port number to obtain an optimal dazzle databaseresponse packet to be analyzed, and analyzing to obtain an application layer message; if the value of the first byte of the message is a character T, considering that the response packet is a query result of the select statement; analyzing the content of each field of the header part according to the total field length, the column number and the separators; analyzing query result content line byline according to the field length, the column number and the separators; assembling the analyzed query result content according to the header field to obtain a query result set; capturing a data packet, filtering through a specified port number to obtain a select statement response packet to be analyzed, further analyzing a header part and query result content of an application layer message, andfinally assembling to obtain a result set, thereby further realizing security auditing of database behaviors, and improving the security of service data.
Description
technical field [0001] The invention belongs to the technical field of communication and network security, and in particular relates to a method for analyzing query result sets of Youxuan database. Background technique [0002] As the core and foundation of information technology, the database carries more and more key business systems, and gradually becomes the most strategic asset in business and public security. The safe and stable operation of the database directly determines whether the business system can be used normally. Database security threats often come from within the enterprise. Malicious damage, illegal operations, and unauthorized access lead to massive data leakage and serious damage; moreover, these operations often do not have attack characteristics and are difficult to be identified by ordinary information security protection systems Out, the database security audit system came into being. [0003] The database audit (and risk control) system is a compli...
