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.

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!

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

Run leaktest from above link you will fail that

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

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

- 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!

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

And it said this
