The perfect operating system....

Simply not true... despite the monumental efforts taken by some... the first firewal in the chain only has to drop (i.e. not process) the packets and nobody is going to get into it no matter what they do. Really... If you need a visualization... you can spray your garden hose at someone and if they are on the other side of a closed window, they won't even know you've done it.

CommonTater, that was a well written explanation, thank you. Still, no matter how secure you believe it can be, there are 2 problems:
1) Whether it is possible to actually combine them all (I don't actually know)
2) There will still be a way around it.

1) Even the lowly 4 port home router DOES combine everying I described.

2) No there won't.

While I may sound paranoid or something saying all this, I am just saying that it is impossible for anything to be 100% secure.
Also, I am only in High School (senior) and I will be going to college as a Computer Engineer starting this September. I have zero experience working in the real world, and have yet to learn a lot of what most members on here already know.
That said, I don't mean that I don't know anything either...

Ahhh well, you'll find out soon enough....

Perhaps I will.
I suppose that I am including simply walking past the firewall and using an inside computer.

I think in the end this argument is rather pointless.
As you are saying, it does seem rather impossible to hack from a distance, but as I said, you can just walk in the building and use an inside computer that is on the INSIDE of the firewall (again, this is not plausible...).

But seriously, thanks for writing that up. It made more sense than trying to read the 6 links zzz supplied (no offense, just low on time).

Really, I kid you not... This TV show stuff where some guy gets into a computer in 20 seconds or less, wrecks havoc on it and then leaves no trace... it simply that... TV show stuff. In real life it's as simple as "If you can't connect to it, you are crap out of luck."

Never once have I said it was easy or plausible.
I merely said it could be done.

See, Lordbob... In real world, you need to make sacrifices... Here's the analogy, if you want your home to be 100% break in proof, what would you do? The logical thing will be not making any doors, just concrete wall all around the house, including roof and floor. It becomes one impenetrable space, but what good would that be? You can't get in, right? That's why you have a door. With one door, you have one security hole already. How do you lock your door? you put a padlock on it. These are how the real world works.

It's the same in the internetwork world, can you have a 100% bulletproof firewall? I say YES - but there is a catch. Let's say we make 100% impenetrable but simple firewall, the first limitation is, you cannot in any way have an open port (this means no hosting your online game, no NAT OK in your Bittorrent clients, and similar limitation in apps that needs an open port). What you need is easy, 2 sets of your favorite broadband router, one will be facing your LAN, the other one will be facing your Internet. The connection diagram will look like this:

LAN >1st Firewall > 2nd Firewall > 3rd Firewall (presumably DSL modem) ---> Internet

Having 1 firewall in place already made MANY people have issues with closed ports, can't have green NAT indicator in BT clients, slow speed in BT apps, let alone THREE of them... This is just a simple form of impenetrable shield for your network. With CommonTater's explanation, this 3 layer of Firewalls is impenetrable... The setup I talked about few posts before has earth to moon distance difference in security level, auditing capabilities, safety measures, everything... It's like you used to your speed at crawling - to suddenly ride an ENZO Ferrari with it's 5 axis traction control, 500++ BHP at wheel, super fast transmission, computer assisted suspension, heaven and earth difference in every level... You know what IP address trying what port in your firewall, when, what the packet content is, is it dropped, if it's not dropped, who receive it, when, and what was the reply, why is it replying, and so on and so on and so on... You can control EVERY ASPECT of network traffic coming and going from and to your network. This is 100% bulletproof.

It's not clear if Hal is an OS, or simply hardware though

Neither really. He was initially programmed, which would make him software based but then he became an 'entity' unto himself. Loosely put, his hardware was just his 'body'.

I suppose, but I got the idea that Hal was run by crystals, which I assumed contained the programming, rather than merely power (Star Trek dilithium). Would such programming be called "software"?

Technically, I would say so.
