Several languages and technologies have been proposed as, e.g., the standard XACML. However, developing real-world systems using such approaches is still a tricky task, being them complex and error-prone. To overcome such difficulties, we advocate the use of FACPL, a formal policy language inspired to but simpler than XACML. FACPL has an intuitive syntax, a mathematical semantics and easy-to-use software tools supporting policy development and enforcement. We illustrate potentialities and effectiveness of our approach through a case study from the Cloud computing domain.
