基于云端计算架构的恶意代码联合防御机制
Joint defense mechanism of malicious code based on cloud and client computing architecture
摘要
Abstract
In order to solve a series of deficiencies in current anti-virus software, such as lagging behind the production of malicious codes, a new joint defense mechanism of malicious code based on the cloud & client computing architecture is proposed, which is suitable for both the Intemet and the Intranet computing environment. Firstly, the traditional cloud computing is expanded into the cloud & client computing. The server-side cluster and user-side terminals are both facilitated playing their respective advantages and utilizing the linkage between each other. A variety of malicious code defense engines are integrated in the server-side cluster. The large-scale terminal nodes are responsible for providing reports of malicious code, making the network and every node effectively protected against malicious code attacks in time. The architecture and workflow of the cloud-&-client-based joint defense mechanism of malicious code is described in detail. In order to improve system performance further, the evaluation and sorting algorithm of malicious code report is also presented,with which the most valuable reports can be processed by the system in time. Simulation experiments and system performance analysis were implemented to test the efficiency of algorithm, the malicious code defending ability of the system, the load of servers and the traffic of networks. The results show that the mechanism can effectively resist endless malicious codes of all kinds with low costs.关键词
