Electric power Web application mimicry defense system

Abstract

The invention discloses an electric power Web application mimicry defense system. The system comprises an information fragment randomized transmission module, a request distribution balancing module,a response redundancy voter, a non-similar Web virtual machine pool, a dynamic executor scheduler and a database instruction isomerization module; the dynamic executor scheduler is used for controlling the state of each Web service executor; the information fragment randomized transmission module fragments and randomizes Web service requests; and the request distribution balancing module dynamically distributes each Web service request to a plurality of heterogeneous redundant Web service executors, processes the same Web service request in a non-cooperative manner, and returns response information to the response redundancy voter for voting. According to the electric power Web application mimicry defense system, the uncertainty of the system is increased, the vulnerability utilization feasibility on which attacks depend is destroyed, and the probability that the system is successfully attacked is reduced; through the design of a voting mechanism, abnormal feedback information of attacks is detected and filtered, so that the system is prevented from being threatened by unknown vulnerabilities.

Description

technical field [0001] The invention belongs to the field of electric power information security, and in particular relates to a power web application mimic defense system. Background technique [0002] With the popularization of electric power information systems and the continuous accumulation of data, electric power production, scheduling, and marketing are increasingly dependent on information systems, and more and more Web application systems based on B / S architecture have been built and put into use. Accompanied by this, the attack methods based on the application layer show an explosive growth trend and are constantly being updated, which brings serious hidden dangers to the security of the business system. The main risks of the power enterprise Web application system come from the loopholes and flaws in the operating system and the system itself. Attackers can use these loopholes and flaws to attack the application system. The current major Web application security l...
