I disagree... The admins should definetely know about the pen-testing.
For example, sometimes politics at the top may keep the mgmt from alerting each
other as to what's going on, or perhaps trying to hide it from other mgmt in an
attempt to prove the network is insecure.
We had one such incident where a sec. team was hired to pen-test the network by
someone who only "owned" a segment of the network. Because this person didn't
know what they were doing the sec. team attacked the whole network causing huge
amounts of noise.
That threw us into a panic and since they were on our LAN we shut down their
ports. Then a big pissing match occurred because they wasted our time and got so
many of our security team in an uproar trying to find out what was happening.
Admin responses can be measured against real life threats such as worms/virii or
planned attack/response "games".
If you're worried that your admins only act under a microscope than that's
already a HR problem and should be dealt with as such.
Cheers,
Harry
