Hard to tell. What I have done in the past is install a hub/switch |
12 |
outside your firewall/DMZ with several systems to perform 'mock tests' |
13 |
via standard penetration tests, packet flooding, DoS, etc etc depending |
14 |
on your suspicions, and pound on your net |

Pentoo linux is also an excellent tool. |
