George,

I used to work for a WISP that used 802.11. I think your boss would be
amazed at how far off I can be and still connect to your network. If you
have a wireless network, you have to assume that the RF is not secure unless
you do in-depth RF planning, a survey and remediate with RF absorbing paint
and what not.

It sounds like your boss is lazy and doesn't want to deal with the issue so
he's throwing out any old argument. Its really as simple as this: Either
protecting the data is important or its not. His argument says that its
not, so why not take down your firewall and publicly address your entire
organization?

As for what a hacker can do... Absolutely anything that an authorized user
can do. You seem flippant about gathering usernames and passwords, but this
is easy and from there one can use the stolen privileges to wreak havoc.
Unless your VPN solution requires a certificate that can't be acquired for
the outside, a hacker just needs to get a single username and password combo
to get in to your core network.

If your accounting system uses direct wire transfers for bill payments, that
is at risk. One could open up a dummy bank account, and create a new vendor
in your system and initiate a transfer to the account.

I guarantee that a hacker can read your CEOs email and send email as your
CEO. The social engineering power of sending an email as your CEO is
enormous.

Your CEO probably uses the same password for his network logon as he does
for his electronic banking... Once a hacker has access to that, your
identity is toast.

Customer data... I'm not sure your industry, but if you store any customer
financial data such as credit cards, that is exposed.

The list is never ending...
