Embodiment

[0080] For the application of mimic defense technology in large-scale websites, a data access middleware between heterogeneous executives and databases is designed. Its simplified high-availability architecture is as follows Figure 4 shown. First of all, the configuration center collects the configuration information of each library in the database cluster, including IP address, port, etc. The monitoring service module is responsible for monitoring the database cluster in real time, and if the data information changes, it will send the changed information to the configuration center. At the same time, the data middleware monitors the configuration center in real time and responds accordingly.

[0081] After a series of distribution judgments, the heterogeneous executive sends the client request to the data access middleware. In order to solve the database redundancy problem and most data inconsistency problems, we simplify n database clusters to one. Due to the many-to-one ...

Abstract

The invention provides a high-performance data access system and method for a mimicry defense architecture, and the system comprises: an SQL attack detection module which is used for integrating an SQL injection detection algorithm in order to detect a non-bypass SQL attack which cannot be defended by mimicry, and discarding a statement once the statement is detected to contain SQL injection; theSQL request processing module that is used for processing an SQL request and reducing the access pressure of a single node by adopting a read-write separation technology; and the database request processing module that uses a database slicing technology to meet application requirements by subsequently adding nodes. According to the invention, n database clusters are simplified into one database cluster, so that the redundancy of a background database is removed. According to the invention, the data request combination of each heterogeneous execution body can be efficiently realized, and the problem of high concurrent access is solved. And a defense mechanism is added to the middleware to make up for security performance reduction caused by the number of database clusters.

Description

technical field [0001] The present invention relates to the technical field of mimicry defense, in particular to a high-performance data access system and method of a mimicry defense architecture. Background technique [0002] Mimic defense technology: It is an institutional mechanism for information systems or control devices with endogenous security features. It is to design the intrinsic functions of the target system on the basis of dynamic heterogeneous redundancy (DHR) architecture, and to introduce the verdict based on the mimic camouflage strategy. A fusion defense function obtained after the mechanism, policy scheduling mechanism, negative feedback control mechanism and multi-dimensional dynamic reconstruction mechanism. [0003] Dynamic heterogeneous redundant architecture: This architecture is a closed-loop iterative multi-dimensional dynamic reconstruction robust control structure composed of equivalent heterogeneous executives, input agents, output agents, decis...
