Web Services security is a major concern in the web engineering domain. Several approaches emphasizing Secure Web Services Design (SWSD) process have been proposed. However, they provide a little guidance as to what developers should do exactly to conduct this highly intellectual process. SWSD practices cannot be defined independently of the situation in which they are applied. To address this challenge, we propose an approach for guiding the construction and execution of situational SWSD methods by reengineering and integrating different existing SWSD method components suited to the specific situation on hand.
