Dear all,

I just recieved a message on my Mac OS X system telling me (loosely translated from Dutch):

"The network has been temporarily disabled because the network's security was breached." (It's a wireless WPA2-PSK secured network BTW)

I looked in the logs of my router (a Zyxel P-2602HW-D1A) only to see a few (outbound) "syn flood TCP ATTACK" logs, but those were from like a week ago, other than that nothing. What tools on Mac OS X do I have to analyse this security breach occurence? Are there some security logs on Mac OS X that I can inspect?

What other measurements should I take? And how serious should I take this warning from Mac OS X?

System: Macbook Pro Intel Core 2 Duo 2.2 Ghz
OS: Mac OS X 10.5.8
Network: wireless WPA2-PSK
Relevant software: Parallels Desktop with Windows XP (was open, but stopped at the time)

Other systems on my network:
Windows XP SP3 desktop (was running at the time)

If you need any more info, don't hestitate to ask.

Thanks in advance.
