[Zope] Is Zope susceptible to denial of service attacks?

Helo every body. I'm testing zope (2.5.1) and i would like to know your experience about this stuff. Is zope suceptible to dos attacks? Or is better to run behind Apache/Squid? Another subject: I have detected with netcat http connections that Z2.log file hasn't logged, How can it be? ..........................................................
