For quite some time, now, I've been subscribed to a newsletter published by Leo Notenboom. He's become my guru. If I have a question about something...well...something computer related...the first thing I do is visit the Ask Leo! website. His newsletter arrives promptly Tuesday morning and it's always filled with lots of interesting stuff. Some stuff more interesting, to me, than others but, always, there's at least one interesting tidbit that I find useful. Here's a question from today's edition:
I can't pass a firewall test, what should I do?
How important is it to test your firewall with a firewall test? I've read about many firewall tests like Shields Up, and I've thought about using them. I know that firewall tests check for open ports, so how do ports become open and vulnerable in the first place? Is there really any way to avoid that? I do not use my computer for much other than simple surfing and I never download anything. I have my firewall set on learning mode. Would a firewall test be more important for someone who downloads, plays games, etc?
I read that many of these tests are easy to fail for reasons most casuals users would not understand. I do not understand very much about firewalls and do not understand some settings enough to change them. I would not want to take a firewall test for it to tell me I've failed, and then spent days trying to figure out why, when in truth my firewall is fine.
Leo's Answer:
"I love Steve Gibson, and his firewall testing utility Shields Up, I really do. Unfortunately Steve's taken a rather extreme position in how he reports your firewall's status - anything less that total invisibility is labeled with a big red "FAILED".
"In my opinion that's both impractical, and unnecessarily alarming for the average user.
"But the test itself, which I FAILED right here at home, returns some very valuable information nonetheless.

Final Thoughts
Because I know his newsletter always has at least one, and usually more, interesting questions and answers I'm planning on making this little entry a weekly thing (assuming it's okay with Leo!). I'll only be posting one or two bits from the newsletter, though, and I'd urge you to subscribe. You can sign up at http://newsletter.ask-leo.com.
