Overview: In recent years, the importance of operating in and protecting the cyber domain has gained much attention. As long as our nation relies on computer networks as a foundation for military and economic power, our national and economic security are at risk through the cyber domain. Cyber attacks on US industry and government systems severely impact our economy and ability to execute modern network-centric warfare.
Our reliance on networked systems and the high costs associated with cyber attacks have led many leaders in the US government and Department of Defense to focus resources toward developing a strategy for deterring adversaries from attacking our networks in the first place. This effort has led to much debate about the question, is cyber deterrence possible? Deterrence in the cyber domain is drastically different and far more complicated than in other military domains (air, land, sea, and space). Cyber weapons and offensive cyber techniques are relatively inexpensive and easily obtained or developed.
The number of adversary groups capable of attacking US networks is large, and our ability to deter each group will vary based on its motives and levels of risk tolerance. An effective cyber deterrence strategy must be multilayered and use all instruments of US national power. This paper discusses the difficulties of deterring unwanted cyber activities, provides some realistic expectations for a deterrence strategy, and offers proposals to help mitigate the problems.
