The Heisenbot Uncertainty Problem: Challenges in Separating Bots from Chaff

چکیده
In this paper we highlight a number of challenges that arise in using crawling to measure the size, topology, and dynamism of distributed botnets. These challenges include traffic due to unrelated applications, address aliasing, and other active participants on the network such as poisoners. Based upon experience developing a crawler for the Storm botnet, we describe each of the issues we encountered in practice, our approach for managing the underlying ambiguity, and the kind of errors we believe it introduces into our estimates.

Capacitor Placement in Distorted Distribution Network Subject to Wind and Load Uncertainty
Utilizing capacitor banks is very conventional in distribution network in order for local compensation of reactive power. This will be more important considering uncertainties including wind generation and loads uncertainty. Harmonics and non-linear loads are other challenges in power system which complicates the capacitor placement problem. Thus, uncertainty and network harmonics have been con...
متن کاملRule-based joint fuzzy and probabilistic networks
One of the important challenges in Graphical models is the problem of dealing with the uncertainties in the problem. Among graphical networks, fuzzy cognitive map is only capable of modeling fuzzy uncertainty and the Bayesian network is only capable of modeling probabilistic uncertainty. In many real issues, we are faced with both fuzzy and probabilistic uncertainties. In these cases, the propo...
