How about old school windows like 3.11 or something around that time? Dos?

Well and of course unix/linux.

I could say alot on this. But I think I'll just simply no. Make that capital NO.

In fact its so insecure... years and years later, viruses made for DOS can still infect a windows system, just for having DOS compatibility.

Tis bad.

This is true. I believe that there were security holes in XP in the first releases that were first reported early on in the NT4 days.

Nuts. My ventilation system is a wee bit small for a shark. Oh well, maybe if I mess with the config file enough I can get a smaller shark.

There *are* some very secure OSes out there, being used for special purposes by the government. Once upon a time, it was my job to make sure that the operating system we used maintained it's "A-1" rating, meaning it was considered fully multi-level secure. (Which means that no matter who you were, if you accessed the system, you couldn't see anything that your weren't supposed to.)

While some of these are still in use today, they are special purpose, and have no connectivity to the "outside world", for obvious reasons. ;)

Most secure OS?

Well, not what NORAD was running in the film "Wargames", that's for sure.

Actually, I think the most secure OS is the one in a concrete bunker buried deep in the Nevada desert, with a five mile no fly zone, auto-cannon defenses, 5 consecutive electrified fences, minefields and no connection to the outside world whatsoever. (It runs off it's own nuclear fusion generator. :D)

Also, killer satellites, so that any life form that comes within two miles gets incinerated with a huge frickin' laser beam.

Nuclear fusion! I knew they've been keeping something from the rest of the world!
I'm not trying to nit-pick here, but it's something left over from a grade 12 physics discussion - it would be a nuclear fission reactor, as the matter breaks down and gives you radioactive waste.

Who said it left radioactive waste? hacker_supreme just said it generated power...heh

People always say that right before preceding to nit-pick for some reason. Fission, fusion. The point is don't go messing around concrete bunkers in the Nevada dessert.

BTW, Who wants dessert? :p

I've got the pick-nit basket and some 12th grade fyshics books. I rented it from the lieberry, but we better hurry and reed it before its dew back Twosday. So we probably shouldn't waist anytime. :D

phantom_cyph 04-25-2007 05:36 PM

Fission? Lol-good luck with that. You have to have a generator 'generate' a reaction at approx. 15.6 million degrees Kelvin with a pressure of 250 billion atmospheres.

(standard temp is 273 K and pressure is 1 atm)

But anyway, I think Windows 3.1 with high-speed internet is the securest you can get. lol

Actually, I think OpenBSD is the most secure. (thats what I've heard anyway)

rocket357 04-25-2007 08:07 PM

Not to "nit-pick", but fission = breaking down (i.e. uranium fuel), and fusion = building up (hydrogen bombs, etc...). The first one is dangerous because if it gets past a certain point, it'll run out of control ("conventional" nuclear reactor). The second one is the one that requires extreme pressure and temperature and will die if sufficient pressure/temperature isn't maintained.

But again, who's arguing semantics? heh



I vote for the honeynet project for being secure...They haven't been cracked in FOREVER! =)

phantom_cyph 04-25-2007 08:33 PM

Fusion is the only type of nuclear reaction that we can currently 'initiate'. Fission is what is used in the Sun.

In the sun however, it looks like this:

2 H --> energy (c) + He

The "security" of an operating system, just like the "security" of a house or a bank-vault, is primarily a function of (a) how determined the attacker is to get in, and (b) how inattentive or uninformed or careless the owners may be.

The causes of intrusion are fundamentally human causes. Many a cat-burglar has confessed that he found the front door unlocked and simply walked inside... perhaps carrying a pizza box.

Operating systems are the same way. The biggest problem with the "famously insecure Windows system" is not the Windows system nor its security-model: rather, it's that security is normally turned off, the user is an all-powerful user with no password, and (in the case of "Home" Editions) the necessary security-tools aren't even installed!

Linux systems can be almost as vulnerable!

Bear in mind that most burglars and vandals are simply opportunists, going from door to door. If you take the slightest precautions to make your system even slightly "difficult to break into," they are most likely going to pass you by for easier pickings.

phantom_cyph 04-25-2007 08:45 PM

Key word in the above post being "can" in the sentence "Linux systems can be almost as vulnerable!".

I have visited sites that I knew had viruses that screwed my Windoze computer over and went back using CentOS, nothing happened. At this point, rootkits aren't being made as fast as viruses.

So what's your point? I have two of them in my kitchen.
