The second one is the minimum robustness
which SecMan can provide according to the less
secure mechanism it can pick up in the SSPD. We
can see in figure 7 that SecMan adapts for each new
ATS flow the robustness level it provides thanks to
its adaptive algorithm. The robustness is always
better than the minimum robustness level considering
initial application security needs but not equal to the
maximum level of robustness given than this last
value is not the optimal one for network and system
resource allocation (as we are going to see in the next
paragraph).
