The development of security visualization applications must involve the user in the design process in order to create usable systems. However, it is all too easy to lose track of the user during the design and development process, even though upfront investment in extensive user requirements gathering has proven benefits. To address this challenge, we adapt a user-centered design method called personas that enables effective requirements capture for varying scopes of requirements-gathering efforts, and, when used properly, keeps the user involved at every step of the process from design to evaluation.
