Several approaches might mitigate cyberthreats to critical infrastructure and information technology targets. Among them are efforts to defend the information systems that support important infrastructure, to deter enemies from cyberattacks on those systems, to reduce or eliminate the forces that might be used in cyberattacks, or to reach arms control agreements that limit or proscribe such cyberattacks.   a0096-3402
