non-vulnerable system

To be listed as a non-vulnerable system, a system must be potentially vulnerable to the exploit. For example, it is unlikely that a Microsoft OS vulnerability would also effect the Linux OS because of fundamental differences. As a result, even though the Linux OS is not vulnerable, it would not be listed as a non-vulnerable system.
