    I don't know a ton about firewalls. I'm looking for a lot of information.

    I know that software firewalls are often stateful/ aware of multiple packets. I know they can monitor inbound and outbound and inbounds that are unsolicited are almost always blocked by default.

    Are there ways to break into them? Known issues? What other features?

    I'm looking to learn as much as possible about this.

    The Stickys in this forum I found really useful, particularly the links in CrazyM's . They are old but it's firewalls we are talking about so most is still relevant.

    Thanks. I'm trying to learn about them in depth. I will check that book out.

    From what I understand they're essentially a set of rules to determine whether ot not to drop packets and some dps.

    Nothing to do with the functionality.

    But why the word "Fire", where does it come from, or wich person named it?
    I can understand the use of the word "Wall" but not Fire really.

    It's not that I am against it, just curious :)

    Thanks JR :)

    I did read the Swedish Wiki page about Firewalls but it didn't include any history about them. But sometimes it's worth checking out the English one as well.

    Though at first I thought I would mention "Maybe it has something to do with the firewalls that we have in our houses/buildings". But I didn't since I actually thought that they didn't have anything to do with them. :p

    SweX, you're welcome!

    You are not alone in the confusion. The first time I heard the term "firewall" was during jet engine mechanic training, and in that world, a firewall is a barrier that separates the compressor and combustion sections of an engine. My first software "firewall" exposure was BlackICE Defender ages ago.

    I see. Yea it sounds like we got firewalls both here and there.... Buildings, Jet engines, Computers.....

    Hehe I remember BlackICE (from IBM if memory serves me well) But I did never try it out though :D

    I think Firestop Is the politically correct term.:p IMO Intrusion wall fits better then firewall for computers since it has nothing to do with Flames.
