| Summary/Abstract |
It is widely believed that cyberspace is offense dominant because of technical characteristics that undermine deterrence and defense. This argument mistakes the ease of deception on the Internet for a categorical ease of attack. As intelligence agencies have long known, deception is a double-edged sword. Covert attackers must exercise restraint against complex targets in order to avoid compromises resulting in mission failure or retaliation. More importantly, defenders can also employ deceptive concealment and ruses to confuse or ensnare aggressors. Indeed, deception can reinvigorate traditional strategies of deterrence and defense against cyber threats, as computer security practitioners have already discovered. The strategy of deception has other important implications: as deterrence became foundational in the nuclear era, deception should rise in prominence in a world that increasingly depends on technology to mediate interaction.
