Changing consumer behavior drives the demand for convenient and easy-to-use mobile applications across industries. This also impacts the financial sector. Banks are eager to offer their services as mobile applications to match the modern consumer needs. The mobile applications are not independently able to provide the required functionality; they interact with the existing core business functions by consuming secure Web Services over the Internet. The thesis analyses the problem of how a bank can enable a new secure distribution and communication channel via the mobile applications. This new channel must be able to interact with existing core systems. The problem is investigated from different axis related to Web Services protocols suitable for mobile use, security solutions for the communication protocols and the required support available in the selected mobile operating systems. The result of the analysis is an architectural description to fulfil the presented requirements. In addition to constructing the architecture, the thesis also describes some of the more advanced threats targeted against mobile apps and Web Services and provides mitigation schemes for the threats. The selected architecture contains a modular security solution that can be utilized outside of the financial context as well.
