 Help researchers identify the type of responses that are most effective against botnets  Design Goals  assist the defenders in identifying possible types of botnets  describe key properties of botnet classes

Estimate of overall utility. Measure the largest number of bots that can receive instructions and participate in an attack. Average amount of bandwidth that a bot can contribute, denoted by B.

Network diameter is one means of expressing this efficiency. This is the average geodesic length of a network.

Clustering coefficient measures the average degree of local transitivity. The transitivity measure index generally captures the robustness of a botnet

Random graphs are created to avoid creating predictable flows. In a random graph, each node is connected with equal probability to the other N-1 nodes. The chance that a bot has a degree of k is the binomial distribution:
