Fundamental limits for optimal reactive defense
	• Every host participates in the blocking strategy. This is the best-case scenario; lower bound on reality • Success metric is % of hosts infected at 24 hours. • Simulations based on 360,000 victims. – worm rate (probes/sec) and reaction time parameters – 100 runs of each scenario • Note: The success metric for other numbers of victims can be found by scaling the rate. (e.g., for 3.6M victims, multiply rate by 10).
