Abstract: As a strategy of defense, deterrence doctrine is usually used in traditional strategic spaces including the land, sea, air and outer space, and is deemed to be valid. But, in consideration that cyberspace is fundamentally different in all aspects from traditional strategic spaces, it is so controversial whether deterrence theory can be used to secure cyberspace. Based on these considerations above, this paper combed and summarized academic debates on cyber deterrence among American, European and Chinese scholars. The authors think: 1) cyber deterrence research is not only valuable on policy decision?making but also on security theory development; 2) if deterrence as a strategy to secure cyberspace can be enforced, two questions must be studied firstly: ① we must engage and understand the role of punishment in different kinds of cyber attacks; ② we must clarify the responsibility of the third parties, work and promote security cooperation with all stakeholders.

Key words: cyber deterrence, punishment, retaliatory, third party, cyberspace
