Usability, Security and Healthcare Systems: Design, Challenges and Perspectives

It's well acknowledged that the field of usable security recognizes that to be secured, a system must be usable. Even the most highly secured application system will fail in practice if the intended users cannot use it properly. In this research we focus on commercial of the shelf application end users. Security professionals also have an important role because the consequences of usability problems can potentially leave the entire networks vulnerable to attack. We believe that techniques are needed for building application systems that are usable, scalable and secure. After all it's not the responsibility of the end users to make sure an application is secured but the developer's job to make it usable and secure. So the progress in usability can contribute to the development and maintenance of dependable application system, especially if they can assist with scalability. Usability is an example of two-way interdependence; a system that is not scalable and not dependable is likely to be difficult to use, and vice versa. A system that is not usable is not likely to be dependable. This article aims to provide guidelines for designing and evaluating applications for security, usability, and scalability.
