Research On The Key Technologies Of Virus Protection In The Cloud Security Environment

Facing the facts of viral diversification and the complexity of the malicious attacks, traditional signature-based detection solution for viral diversification and the complexity of the malicious attacks has been increasingly unable to meet the security requirements in our daily life. In addition, the development of the mobile Internet, the widespread use of smart mobile operating system and the increasing number of economic and political interests carried by the mobile Internet makes malicious intrusions more rampant and lead to more serious harm. For this reason, it is an urgent need for effective and accurate antivirus program to improve the security of the entire Internet.Currently, with its high computing power and storage capacity, cloud computing with its high computing power and storage capacity has drawn much attention. Therefore, the antivirus vendors have proposed the concept of cloud security.This paper firstly introduces the prevalent cloud security solutions at present. In order to integrate the advantages of them and make up for their shortcomings, this paper put forward a more comprehensive and efficient cloud security architecture including server clusters and mass clients. The server-side has two core modules. One is based on the reputation of resources and responsible for the active defense based reputation of resources, and the other completes passive defense by using technology of virus behavior analysis. They cooperate and share information with each other to improve the accuracy of reputation service and the effectiveness of virus analysis. The multi-level access control model in client is employed to complete local defense, threat prevention and the discovery of suspicious virus. The server clusters and mass users work together and finish both active prevention and passive defense. So this solution gets the capabilities of comprehensive and powerful virus defense.As we know, the android smart mobile operating system suffered from malicious attacks frequently. By studying the classifications of the malicious attacks on android and the corresponding defense technologies, this paper designs an android-based cloud antivirus client, which includes the malicious intrusion monitoring module, the core analysis module, and the malicious intrusion response module. The core analysis module uses three detection structures to achieve full protection. Finally, this paper set up a small cloud computing platform and detects the malicious samples. The evaluation results prove the validity and the accuracy of the cloud security architecture.
