After my post yesterday, then my article in the newletter, a few people feel that I am way off base in recommending that most people don't need a firewall.
First, Windows XP has a firewall built-in, if you use DSL or you have your cable Internet running through a Router, then you have a hardware firewall. My comments are pertaining to the extra software firewalls like ZoneAlarm and Sygate.
My cool brother-in-law, Nishan, emailed me with a few comments about my articles. He designs and maintains a huge database for a medical billing company in Oregon. In other words, unlike me, he is a true geek. I merely pretend to understand when people talk about SQL, Linux, and Apache, Nishan understands this stuff.
Since he spends his days combatting stuff like hackers his systems must be extremely tight. So, I can see where he's coming from.
Below is his email to me followed by my reply.
I just read your newsletter. I respectfully disagree. There is a simple process of implementing a software keylogger which sends user data back to "Hack Central". And that another reason hackers hack into computers is for DoS attacks. By implementing remote bots, the hacker can take down sites or send spam for those bots.
I do agree that the person with the dialup doesn't need a firewall.
