Defence Schemes From Attacker's Own Reward Processes

Botnet economics and devising defence schemes from attackers own reward processes

This paper focuses on botnet economics and design of defensive strategies. It takes the view that by combining scarce information on the attackers’ business models, with rational economic analysis of these business processes, one can identify design rules for economic defense mechanisms which the target can implement, often in a cheap way in addition to technical means. A short survey of game t...

Asymptotic Behavior of Multivariate Reward Processes with Nonlinear Reward Functions

COVARIANCE MATRIX OF MULTIVARIATE REWARD PROCESSES WITH NONLINEAR REWARD FUNCTIONS

Multivariate reward processes with reward functions of constant rates, defined on a semi-Markov process, first were studied by Masuda and Sumita, 1991. Reward processes with nonlinear reward functions were introduced in Soltani, 1996. In this work we study a multivariate process , , where are reward processes with nonlinear reward functions respectively. The Laplace transform of the covar...

Avoiding Punishment Is Its Own Reward

The expression of the EGF receptor, c-erbB-2 and PDGF receptor proteins has been studied in a series of human brain tumour biopsies and cell lines. Western blotting was used to determine the amount of protein present and their intrinsic and ligand promoted enzyme activities were studied by immunoprecipitation followed by autophosphorylation. EGF receptors were found to be expressed at very high...
