Embodiment

[0055] Such as figure 1 As shown, a libpcap-based clinical risk early warning method, the steps are as follows:

[0056] S101. Obtain a request packet of a request sent by a client.

[0057] S102. Analyze the request packet according to a plurality of preset analysis rules, and generate an analysis result including the database table name and the field value of the SQL statement.

[0058] S103, calling the database table name and SQL statement field value of the analysis result, judging whether it matches the database table name and SQL statement field value of the preset normal value, if yes, sending a normal signal, and if not, sending an early warning signal.

[0059] In the foregoing embodiment, by setting up port mirroring, the full-flow network message is obtained from libpcap, the TCP message is parsed from the network message, and a plurality of TDS messages and response packets are obtained according to the TCP message; it is saved for analyzing the TDS message Mult...

Abstract

The invention discloses a clinical risk early warning method based on libpcap. The method comprises the following steps of a, obtaining a request packet of a request sent by a client; b, analyzing therequest packet according to a plurality of preset analysis rules to generate an analysis result containing a database table name and an SQL statement field value; and c, calling the database table name and the SQL statement field value of the analysis result, judging whether the database table name and the SQL statement field value are matched with the database table name and the SQL statement field value of a preset normal value or not, if so, sending a normal signal, and if not, sending an early warning signal. The invention further discloses a clinical risk early warning system based on the libpcap. According to the method, potential safety hazards of internal personnel operation can be reduced, potential safety hazards of third-party maintenance personnel are reduced, potential safetyhazards of system account sharing are reduced, and potential safety hazards of users with the highest authority are reduced.

Description

technical field [0001] The invention relates to the field of risk early warning, in particular to a libpcap-based clinical risk early warning method and system. Background technique [0002] With the continuous deepening of enterprise informatization, the business system of enterprises has become more and more complex, and the security problems caused by illegal operations of internal employees and system operation and maintenance personnel have become increasingly prominent. Conventional security products such as firewalls, anti-viruses, and intrusion detection systems can solve some security problems, but they are powerless against violations by insiders. In the process of enterprise development, due to reasons such as strategic positioning and manpower, more and more non-core businesses are outsourced to equipment manufacturers or other professional maintenance companies. How to effectively monitor the operation behavior of equipment manufacturers and maintenance personn...
