Linux losing ground on security front: Study
By JACK KAPICA Globe and Mail Update
E-mail this Article Print this Article
Linux, the operating system that has become the darling of its security-conscious promoters, came out second-best to Microsoft's Windows Server in a new survey released Wednesday.
Security experts at London-based mi2g who have been tracking digital attacks closely for the past three months, specifically because of increased tensions over the war in Iraq, say that Linux-based servers recorded most of the successful breaches.The company said that in May, 19,208 successful breaches worldwide were recorded against Linux-based systems (76 per cent) and 3,801 breaches were recorded against Microsoft Windows systems (15 per cent). Both corporate and government servers were counted.Microsoft Windows-based servers proved to be the more resilient during the war months from March through to May.This is an abrupt change from January, when 53 per cent of all successful and verified hacker attacks were recorded against Microsoft Windows-based systems (10,435) and 34 per cent against Linux (6,688).The company recently reported that three security records were set in May: the highest number of overt attacks in one day (May 4, with 2,576 attacks); the greatest number of attacks for one month, (May, with 23,009); as well as the highest number of attacks in one year (91,088 overt attacks).The company has been tracking attacks since 1995 and maintains its records in its Security Intelligence Products and Systems (SIPS) database. The information is used to estimate economic damage, such as loss of business, productivity, management time, intellectual property rights violations, customer and supplier liabilities and share price decline (where applicable). The database has information on more than 220,000 overt digital attacks and 7,000 hacker groups.The company said there are three main reasons for the increased numbers of successful attacks against Linux systems.First, they said that improperly configured systems running a combination of Linux and third-party applications are vulnerable because they are either too old, do not come with sufficient default security configurations, or the appropriate patches have not been applied.Next, mi2g said that there is a lack of a coherent trustworthy computing initiative within the open-source community. Microsoft, on the other hand, has recently been taking the initiative to inform customers specifically about server management.Finally, Linux is being targeted simply because of its dominant position in the server market. Companies and government agencies are buying Linux to cut the costs of site licences, but are not factoring in the heavy fire from transnational hackers.Open-source software is not cost-effective if the technical experience used to protect the systems is inadequate, and if training costs are not factored in at the start, mi2g said."As automatic attack tools scanning for vulnerabilities become ubiquitous, the on-line system security is heavily dependent on settings and when the last patch was applied," mi2g chairman D.K. Matai said."There are plenty of instances where the server administrator assumes that just because they are running open source they are somehow going to be more secure. There is no such thing as secure computing without following rigorous procedures for monitoring the system software and keeping track of enterprise-wide system configuration."The SIPS database defines successful hacker attacks as incidents in which a hacker group has gained unauthorized access to an on-line system and has made modifications to any part of it while executing data attacks (compromising the integrity of data) or command-and-control attacks (Simple Network Management Protocol control of computers).

That's all fine and dandy, but a bullet proof piece of clothing 'as light as a t-shirt' wouldn't so squat. Kevlar is a pretty light material too, the reason bullet proof vests are so heavy is because of the large impact absorbing plates. Without some impact absorbance, the bullet would just end up dragging a whole bunch of cloth into the gaping hole in your chest. You have to have something to absorb the kinetic energy; and a t-shirt just doesn't cut it.

I notice similaraties with Stephenson's 'The Diamond Age'... You say Carbon Nanotube based memory chip... He calls it rod logic, but it's clearly the same thing
Just wait until we get some vacuum-filled buckyballs and some useful nano-power sourde.
The diamond age is about to begin.
From the article: "The ability to place CNTs directly on a substrate while controlling their spacing, size, and length, provides a high quality image with optimized electron emissions, brightness, color purity and resolution for flat panel displays. Other attempts in this field utilize a "paste" or "print" method of applying CNTs, which to date, have not been able to provide the same level of display image quality, or the potential cost savings of Motorola's NED process."
This brings up some interesting ideas !
What happens when the technology for laying the nanotubes onto substrates becomes so good that we
are able to build car frames or house frames from it(think 3D substrates of nanotubes) ?
How about another question , how easy is it for one to recycle this crap.
We already have problems with millions of old junk PC's and monitors, what happens when you have near indestructable nanotube structures ?

Another potential use for nanotubes are the traces on semiconductors:

This is an anti-Linux article... it'll never make it on Slashdot. Slashdot is not allowed to post anything anti-Linux after they sold out to OSDN. Their political agenda is to always make open source look good and make all corporations like Microsoft look bad.

It seems Nantero has taken a "hint" from IBM by trying to beat them to the punch.
Wired had an article in April of 2000 on a technology called MRAM being developed by Stuart Parkin at IBM. Very interesting stuff, and they had working prototypes before this Nantero thing. From what I can tell, Nantero probably read the same article I did, as the similarities are quite remarkable.
Check it out: http://www.wired.com/wired/archive/8.04/mram.html
The amusing thing about the plastics mentioning is that it really has come true, as far as market penetration. Almost everything that we deal with is plastic, from the bulk of the styling panels on modern automobiles, to grocery bags, to computer parts. Almost every strap connector is made of plastic, and many ropes are plastic-impregnated for strength and longevity. We ship our food in plastic, we filter our water with it. We contain industrial fluids in it. It's everywhere. It's easy to find devices that are nearly 100% plastic, it's nearly impossible to find something with absolutely no plastic in it whatsoever.
Maybe the Buggles album "Age of Plastic" is fully appropriate by name. Certainly the method I use to play it is plastic...

Mr. Timothy, your trying to seduce me
Huh? I don't see anything in the articles about any of those applications increasing in size... Although, it would be pretty sweet to have a growing flat panel display...
Do not read this sig.
The reason that plastics are seen to represent artificiality has nothing to do with their core makeup. It has to do with the fact they are used to replace other materials - in a way that mimics the original material without actually having any of the original material. Examples: faux furs and glasses (both cups and eyeglasses apply here). No matter how close in look and feel a plastic comes to the original material, it is still not really that material - and thus is artificial.

There's an article on the Register outlining the UK Governments proposed investment of £90m (GBP) in nanotechnology over the next six years here. With links to the announcement on the Government News Network. A very little too late perhaps.
...how hard is it to fool most of the fuckwit moderators on here? Like karmawhoring is hard.

Hell, those STILL get modded up for a while before someone finally catches it.

That would be for propaganda. I second grandparent's request and add UNBIASED.
While the strength inherent in the mithril is a component in resisting spear thrusts, it is in fact the Elfish magic that the armor has been imbued with that absorbs and dissipates the force of the blow. This is also the major factor in the delicious nature of Keebler cookies, which are also Elfish.

Newer stuff all the time. As far as fabrics go, I think it's still a great invention, but as with all inventions, it will only do wonders when used properly. In which case it's still has to be handled by us puny hoomans.
What if this new technology enables criminals to get away with stuff they didn't used to?

Betcha when it hits urban industries the taxpayers will be emptying their wallets because of it.
While we're ahead maybe we should start making nano-checks; I wonder what a nanopenny will look like and how many it'll take for my nano jujubee.

p.s. at least I started on topic.
Wired has also had some great articles. My favorite has been the plan for the space elevator. Thick as a piece of paper and a few feed wide, create a ribbon made of nanotubes miles long. Attach one end to a platform in the middle of an ocean. Attach the other end to a station in geo-cync orbit. Have a simple platform crawl up the ribbon into space.
Plus it would make one hell of a great Freefall ride at Great Adventure.
Developers: We can use your help.
I betcha that Robin Williams will be picked up by the first company to really do something with these as a product.
They'll dress him up as Mork on TV and he'll say "Nano Nano" over and over again.
Hmmm...

We are all familiar with the intricities and variations of the most common forms of trolling: vulgar ascii imagery, brutal character attacks, non-sensical charades, highly explicit and disgusting narratives of obscene sexual escapades, et cetera. More complicated trolling involves roleplaying and the clever manipulation of emotion by asserting statements that disconfirm popular notions and/or ideals.
Yes, the most common techniques and favored tactics of trolling are well known. We are famaliar with them, comfortable. The neccassary precautions have been taken and contingency plans have been developed. These famaliar trolls can be easily evaded and repulsed - or even vanquished. We have exhausted our resources to insure our complete defensibility against them.
However, in our rush to defend against these threats, we have ignored the vigilant study of our enemie's evolving tactics. Insidious new shadows of threat grow while we remain oblivious.
A new enemy is upon us. Not contempt with mere juvenalia, the capture of karma is imperative. Beyond the capture of karma, this new foe also demands of us negative and ellicit responses to his actions. There is no subject to which this enemy is not an expert. There is no topic from whence he can not derive humor. His cache of weaponary contains agents far more powerful then mere ascii imagery. Emotion is his puppet. You have been trolled, have a nice day.
how is this off-topic? What is being discussed is the economic possibilities of this material. I for one would love a lighter, unbreakable fly rod.
Fishing in the US is a many-tens-of-billions industry, and it has just as much technology involved as other industries. Have you ever seen one of the newest $50,000 bass fishing boats, freaking GPS fish finders!
Oh, and most fishing rods are made of graphite composites for the sensitivity they present the user. Carbon fiber constuctions are loved for the great rigidity and strength-to-weight ratio, that is why my bike is made of it.
Whenever you notice something like that, a wizard did it.

Remember the old slashdot story that said that carbon nanotubes could absorb UV incredably efficiently (so much so that a camera flash would cause single-walled nanotubes to overheat and combust)? I am wondering why we aren't hearing about super efficient solar cells based on carbon nanotubes. ~90% efficiency would be pretty darn kool! :P The only problem I can think of is that they are still hard/expensive to make, but you would think that some people would be experimenting with this anyway.
The manufacturing machine could be put on a geostationary satellite and could "grow" a thread reaching earth and further out into space.
Its "Fountains of Paradise" time.
Arthur C Clarke must be so pleased. He got right the development and use of satellites, geostationary and orbital, and now this.

I think Larry Niven's idea of impact armor is cooler: lightweight material that is flexible until it's elastic limit is exceeded, at which time it instantaneously hardens into material stronger than steel. Nifty. Looks like Sinclair Molecule Chain may not be that far off either. Now if only we could figure out the General Products Hulls!

An apt description of your dick, loser.
topic is diverging, but there are some amazing tank armor systems that detect the incoming projectile (often a high-mass, low-cross-section sabot - basically a uranium spike) and actually jump off the tank to meet it. The sabot is deflected just enough to hit the main armor slightly skew, destroying the sabot without penetrating the tank. It's just mind-fudgingly amazing that these things can work.

From the article about bullet proof "cloth":
The fibre's toughness probably results from structural changes during stretching
Looks like it does stretch to me. Which was the entire point of my post.
What is "not too distant future" in hype-speak ?
No it's not.
That was in the Sourcebook Fields of Fire for the Shadowrun RPG. (and a damn fine gaming system it is too.)
The bulletproof clothing felt like gel when worn under normal conditions, but when subjected to a shockwave from a projectile or blast moving at or above the speed of sound it would harden into a bodycast of the wearer. After the shock had passed around the wearer, the armour would return to its fluid state. It was available in two models - the original bodysuit which made the wearer immobile until it had re-liquified, and the second-gen stuff which only hardened in the places hit.
The failure mode for a bad roll of the dice when defending against automatic weapons fire would the irreversible hardening of the suit into a permanent cast of the wearer.
A GM I played with allowed one of my teammates to take out a NPC wearing the armour with subsonic silenced rounds. Likewise, knives and arrows passed through it with no side effects other than releasing a vile poisonous goo from the punctured armour straight into the entry wound.
After that the remaining NPC Mercs wore kevlar and ceramic plates over their goo suits.
select sci/tech, gives you multiple sources for articles, a shitload of articles, and updates very often. google wins.
Current offensive frag grenades use a winding of fine brittle wire to make the fragments. On hard ground these tiny staple like projectiles can shred a man three meters away and wound him at ten.
What would a grenade made with a carbon nanotube casing with roving which would shatter into billions of tiny X-ray invisible fragments do? and would the carbon fragments even raise an immune response from the body? or would they be allowed to sit there with no symptoms until they moved one day years later to puncture an artery?

I'm just guessing that our average Joe can't buy, let alone make, a nanotube, even if he had the resources, right?
... so I guess that makes it interesting to nerds and other disaffected types, being intimate with the condition.
Nanotubes are quite volatile in many conditions, just like conventional silicon when it is thoroughly etched with cavities

So its flexible for wear and hard when you get hit! Although, i'm not sure how they got it from being so sticky when its soft.
a lot more of those "priceless" pictures showing up on the net. Girls wearing nanotube clothes, only to have them explode off of them because they were too close to the camera flash.
I don't really know why, but DAMN that was funny. Well done.
> Despite not actually stopping blows, chainmail was still a very good piece of armor....Stopped arrows pretty well, too.
y /longbow.html:
Not true, actually. See, for example, http://gondolin.hist.liv.ac.uk/~azaroth/universit
"a knight of William de Braose was hit by an arrow that went through his mail skirts, his mail leggings, his thigh, back through the other side of the leggings, through the wood of his saddle and into the horse's flank"
Modern tests have shown that mail armour provided little resistace to arrows at typical direct-shot ranges (up to ~30 yards), which is a large part of why the English armies were so effective before the cannons were widely used.
> Without a really incredible amount of force, the spear would never pierce chainmail
For the same reasons, this is also not true. Mail armour was not so hard to pierce with a strong, straight thrust. Landing such an attack undeflected, however, would have been tough against a skilled opponent.
Given the facts that :
- The empirical fact that slashdot moderators ARE (mostly) idiots
- Your moderation goes away if you post in the thread (so the person who thought the post was "FLAMEBAIT" cannot possibly reply with a flame AND moderate the post. And if you moderated instead of replying, it wasn't much of a FLAMEBAIT, now was it?!!).
Why not read the FAQ before squandering your mod points by finding no-good-shits to dump on? Then, instead of trying to push an infinite number of turds below the surface, <blink> go find some good posts to mod up </blink>.In fact, I will go as far as to say that any moderator that does use their finite mod points to mod down bad posts instead of modding up good posts is de facto an idiot. That's not flamebait, that's an honest opinion. Deal with it.
