Embodiment Construction

[0048] The present invention will be further described through the following embodiments in conjunction with the accompanying drawings.

[0049] The bypass database access interception and restoration method is applied in an Oracle database audit system 3 . Such as figure 1 As shown, the network environment is 100M Ethernet, the equipment includes database user 1, Oracle database server 2, and database audit system 3, and the operating platform is Linux. The database audit system 3 is equipped with 100M network detection equipment 31, audit center software 32 and audit management software 33, and is equipped with a MS SQL SERVER database for audit data access. The 100M network detection device 31 is equipped with two 100M network cards, one of which has no IP address and is set to promiscuous mode to listen to data packets in the network, and the other network card is connected to the Oracle database server 2 to keep the internal communication of the audit system normal .

Abstract

A by-pass intercepting and restoring method for database access is characterized by that a database audit system is connected to network between database user and database server for filtering the data the user has accessed from the service port of database server, processing it by by-pass intercepting, and analyzing and restoring the information, so understanding all data accessed by user.

Description

technical field [0001] The invention relates to a method for monitoring and restoring database access, in particular to a method for bypassing database access monitoring and restoring. Background technique [0002] In most application systems, the database is the core of the entire system. Once the database is damaged, the entire system may be paralyzed. In addition to threats to the network layer and operating system of the database host (these are usually prevented by firewalls, intrusion detection and audit products), the database system platform itself faces many threats, such as theft of confidential data, unauthorized database operations, provision of false data, Identity impersonation, etc. Usually, the log function is provided in the database, but these logs have the following defects: [0003] a. It will consume the performance of the database host. The log function will consume a lot of CPU and hard disk resources, and it is difficult to s...
