In this paper we present a verification methodology, using an action-based logic, able to check properties for full CCS terms, allowing also verification on infinite state systems. Obviously, for some properties we are only able to give a semidecision procedure. The idea is to use (a sequence of) finite state transition systems which approximate the, possibly infinite state, transition system corresponding to a term. To this end we define a particular notion of approximation, which is stronger than simulation, suitable to define and prove liveness and safety properties of the process terms.
