This paper proposes the design of a security policy translator in Interface to Network Security Functions (I2NSF) framework. Also, this paper shows the benefits of designing security policy translations. I2NSF is an architecture for providing various Network Security Functions (NSFs) to users. I2NSF user should be able to use NSF even if user has no overall knowledge of NSFs. Generally, policies which are generated by I2NSF user contain abstract data because users do not consider the attributes of NSFs when creating policies. Therefore, the I2NSF framework requires a translator that automatically finds the NSFs which is required for policy when Security Controller receives a security policy from the user and translates it for selected NSFs. We satisfied the above requirements by modularizing the translator through Automata theory.
