More opportunities to be compromised? Maybe. But better chances of
success?.. That may be true only for non-homogenous systems, and on
certain conditions. In a *homogenous* system every component perhaps
has the same probability of successful compromise. Having N replicas
of the database with exactly the same probability P of compromise does
not change the chances of compromise (N*(1/N)*P, which is "N" times
the probability that the particular replica was chosen multiplied by
the probability of success). It is fair to assume that in a homogenous
system the probability of attack is distributed uniformly (1/N).
For the messages in transit to N destinations to be significantly
easier to compromise than one, N must be really large, if we were to
consider analysis of multiple encryptions of the same message.
