Security improvements

Now moving to the security improvements, we are comparing Nano Server with Server Core. As shown in Figure 5 for drivers loaded, we have 73 for Nano and Server Core has 98, Microsoft did not change a lot in the driver's space. However, for services running, they made some significant improvements. In this area, Nano Server had 28 services running versus Server Core which had 47, little less than half. As for ports open, Nano Server was almost a third less compared to Server Core; Nano Server had 12 versus Server Core which had 30. This is the exposure on your network in ways that things can be attacked; vulnerability might be exposed in your systems. The drivers loaded are the hardware drivers and the drivers loaded by the system:
