What Do You Mean No Firewall?
This week my company delivered a new workstation and printer to a client with a home office. An ultra-modern Dell with a huge flat screen monitor and color laser multi-functional printer. Most of the folks I know would give their eye teeth to run a rig like this at home.
Today the client called and asked, “Why don’t I have a firewall?”
I tried to explain that a firewall is an appliance or software package running on a server that “polices” traffic on a network, according to a pre-determined set of instructions. Since he didn’t have a network, a firewall would be overkill. The biggest threat to an operator like him would come from virus infestation, malware and spyware. If he allows his anti-virus and anti-spyware programs to remain up to date and stays away from online porn and “file-sharing” sites then he should be fine.
“But couldn’t someone “hack” my system and… read my email?”
Theoretically, yes, I explained. But that would mean that someone cared enough to do so. And again, since he has no network and no “in-house” email (he’s running “free” POP3 email) then there are far more vulnerabilities outside his home than in it.
At this point understanding was elusive, so I took another tack. “What kind of door do you have on your home?” I asked.
“I don’t know, a regular entry door.” was the response.
“Exactly!” I crowed.
“You know that if you wanted to, and had enough money, you could put a bank vault door up instead of that regular entry door. You could install a timer lock keyed only to your thumbprint. You could get a retinal scanner even.
But then every time you wanted to go get your mail you’d have to go in and out through that thing. And you would have spent more money on protection than the value of the thing protected.”
In the end, to appease the client (who is always right!), I said, “Here is my favorite firewall system (Barracuda). Here is what it will cost you (+-$2000 + install + configure + maintenance = $3500 this year alone).
YOU DON’T NEED THIS. But if you want it, I’ll oblige.
Once again, technology for technology’s sake.
