Offline Mode for Corporate Mobile Client Security Architecture

Preventing data leakage on the mobile client is a crucial security problem. Therefore, additional control and protection should be taken for the confidential data on the mobile clients that leave the boundaries of the organization. This paper presents a novel approach to the security of the corporate mobile clients, in particular when they operate in the offline mode. The presented approach includes the essential conceptualization and the definition of the core methodology to solve the problem of offline mobile security, i.e. the protection of the confidential data in use when the mobile client is not connected to the corporate cloud. The protection of the sensitive data is provided by the combination of cryptographic means and analytics methods to detect malicious user behavior. The proposed security architecture supports the basic mobile client protection principles: minimized traffic load and reduced communication with the cloud; usage of light-weighted operations and an optimized combination of the security methods.
