  abstract =	 {The strong analogy between biological viruses and
                  their computational counterparts has motivated the
                  authors to adapt the techniques of mathematical
                  epidemiology to the study of computer virus
                  propagation. In order to allow for the most general
                  patterns of program sharing, a standard
                  epidemiological model is extended by placing it on a
                  directed graph and a combination of analysis and
                  simulation is used to study its behavior. The
                  conditions under which epidemics are likely to occur
                  are determined, and, in cases where they do, the
                  dynamics of the expected number of infected
                  individuals are examined as a function of time. It
                  is concluded that an imperfect defense against
                  computer viruses can still be highly effective in
                  preventing their widespread proliferation, provided
                  that the infection rate does not exceed a
                  well-defined critical epidemic threshold.},
