An Audit of Server Hardening in Multi-Tenantarchitecture System in Cloud Computing

In cloud computing, multi-tenancy is the architecture in which hardware and software can be shared with multiple users (tenant). In existing system, there is no protection on the operating system level when corporate or individual is reserving any system in cloud computing by default. Most of the corporate or individuals are using either “Single Tenant” or “Multi-Tenant” model. In both of the approach there are vulnerable attacks. And they do not have much knowledge of the “Server Hardening” to secure their servers. The main objective of the proposed system “An Audit of Server Hardening in Multi-Tenant Architecture System in Cloud Computing” is to secure multi-tenancy architecture system. In this model, the server or system is secured by applying technique called ‘Server Hardening’ using Linux server from ‘Amazon’ called “Amazon Elastic Compute Cloud (Amazon EC2”. To audit the level of security a cloud system provides an open source tool called ‘Lynis’. This tool was utilized to determine the state of hardening of the present available system such as Fedora, Red Hat, Ubuntu etc., that cloud services vendors provides. The future of the system, to apply the ‘Server Hardening’ to secure the system or server, need to create a module for major Linux family operating systems like Ubuntu, RedHat and SuSE.
