In this paper we propose the DISC-SeT framework to handle the representation, solution computation and verification of temporal and security requirements in the services composition. The proposed approach provides a flexible event calculus based composition design, that allows for modeling different temporal (response time, time-units and other) and security aspects (access control, confidentiality and others) for Web services with different synchronization modes. The use of a formal approach allows to reason about and verify the security and temporal requirements. Further, as the proposed approach is integrated and builds upon the DISC framework, it allows to learn from run-time security and temporal constraints violations to take recovery actions.
