Re: External Pentests Obsolete?

I am not going to feel the need to prove you wrong here by educating
you on all the ways to penetrate a network. I will just say that I am
having no problems penetrating networks and see no reason why
penetration testing would be obsolete anywhere in the near future.

I do remember reading a report from a competitor earlier in the week
that stated that War Dialing was obsolete even though they found open
modems through the pen test. I thought that was an odd statement to
make considering they actually did the test AND found vulnerable
modems connected to systems!

I think it is way more ethical to consult clients on getting a pen
test especially considering that multiple standards and guidelines
recommend if not demand them to occur on a regular recurring basis
(PCI anyone?).

MAYBE you should not be consulting to do pen tests...
