Organizations are embracing cloud technologies for elasticity and reduced operational costs. Building public cloud systems requires significant planning and upfront costs due to hardware and software requirements. Security is challenging in cloud context due to increased attack surface which can result in serious vulnerabilities if not properly planned. Traditional cryptographic schemes such as PKI help in data protection but they involve complexity in management and lack flexibility in designing access control policy. In this paper, we evaluate Attribute-based encryption schemes for logs preservation and assess performance for various configurations in cloud environment viz., OpenStack. OpenStack is a public cloud software which enables building Infrastructure-as-a-Service platform leveraging the hardware resources, it is large collection of independent components tied together to provide unified service to end users. OpenStack Fuel is a testing framework used by many organizations in automating process of deployment, configuration and testing the OpenStack software. In OpenStack setup lot of sensitive information generated by server components is stored in log files, if the data is not properly preserved it can result in leakage. We use ABE schemes for logs preservation as they overcome challenges associated with certificate management and at the same time provide more flexibility to users compared to traditional cryptosystems. In this paper, we describe cloud infrastructure setup using OpenStack and OpenStack Fuel. We provide reference architecture for building a security framework based on Attribute-based encryption schemes.
