Recently, Virtual Desktop Infrastructure (VDI) has been widely adopted to ensure secure protection of enterprise data and provide users with a centrally managed execution environment. However, user experiences may be restricted due to the limited functionalities of thin clients in VDI. If thick client devices like laptops are used, then data leakage may be possible due to malicious software installed in thick client mobile devices. In this paper, the authors present data firewall, a security framework to manage and protect security sensitive data in thick client mobile devices. Data firewall consists of three components: Virtual Machine (VM) image management, client VM integrity attestation, and key management for protected storage.
