Testing your firewall security
 
Don't know if this has been posted before but the following link performs an online security port scan of your firewall and you can configure which ports you want it to scan.

https://www.grc.com/x/ne.dll?bh0bkyd2

There's also tons of useful utilitys on there too !

Agreed, but he has got a couple of tricks up his sleeve

no offence, but I think I'll be rerfraining from clicking any links whatsoever for a little while! :rolleyes:

The link is the the "Shields Up" site that tests your firewall. Don't worry it's safe to click. It's also a HTTPS site so it's actually secured.

Why so surprised? The Windows firewall is pretty reasonable for free - where it mainly falls down is its (in)ability to prevent malware from connecting outbound. IIRC pretty much everything inbound is blocked by default.

Also available on the GRC site is something called leaktest ?IIRC which checks to see if your firewall monitors such connections

EDIT: here it is http://www.grc.com/lt/leaktest.htm

Vistas firewall has outbound protection but its off by default .I use a simple app called vista forewall control that turns it on ond uses it .Ive had no probs at all with this app for a month or 2

Indeed! Used to visit his site quite a lot and then realised that most of the time he was full of scaremongering.

Re: Testing your firewall security
 
The last time I checked, the site reckoned my PC was invisible on the Internet - unsurprising, as I've been using a router for a while. NAT is a very handy thing for security. :) And that was a Linksys router which didn't have its own firewall. I now have a wireless US Robotics router, which does have a firewall, so unless I get careless - using IE, for example :p: - I should have nothing to worry about. :) To the best of my knowledge, there's no way past a hardware firewall short of physical access...in which case the would-be hacker will have bigger problems than hacking my computer, as I''ll be busy hacking into him! :mad:

Hands off our forum, you filthy scrotes!!!

Not quite true ;) - there should be no direct way to get through a router firewall, but it is quite possible for you to unwittingly download a trojan that opens up a tunnel back to the would be hacker :( That is where a 'decent' software firewall helps.

It says one of my ports is visible but closed :shrug: And it said this

Solicited TCP Packets: RECEIVED (FAILED) — As detailed in the port report below, one or more of your system's ports actively responded to our deliberate attempts to establish a connection. It is generally possible to increase your system's security by hiding it from the probes of potentially hostile hackers. Please see the details presented by the specific port links below, as well as the various resources on this site, and in our extremely helpful and active user community.

His point is that the starting point for a random hacker would be to scan a range of IP addresses. If your ports are all invisible, he doesn't know whether anyone is using that IP. If you have a closed but visible port, the hacker knows there is computer using that IP and depending on the visible port may even be able to determine what OS/firewall is on there. That's the theory anyway.
In practice, I wouldn't worry about it too much.

Good point. Does Norton qualify as a decent firewall? :p:

Mind you, many trojans gain access via popups...and I'm running Firefox, which of course tells popups to get stuffed unless you say otherwise. :p: I'm also running NoScript (thanks to Carol a.k.a. Bald Eagle of the Windows Annoyances forum for that one!), so malicious Java code can go play with itself, too. :D
