Protecting Networks Is Just a Game

ScienceDaily (July 28, 2011) – How can an organization detect the onset of an attack on its computer network giving it time to respond quickly and block any intrusion or compromise of its data? Modern firewalls and other technology are already in place, but these have not prevented major attacks on prominent networks in recent months. Now, information technologist Heechang Shin of Iona College in New Rochelle, NY, has used game theory to develop a defense mechanism for networks that is more effective than previous approaches. Writing in the International Journal of Business Continuity and Risk Management, Shin explains that with the tremendous growth in numbers of computing and other devices connected to networks, information systems security has become an issue of serious global concern. He points out that each incident might not only cause significant disruption to services affecting many thousands of people but for a commercial operation can take as much as 1 percent of annual sales, per incident. That number amounts to tens of millions of dollars for the average publicly listed company, Shin says.

Shin has now developed an effective anti-hacking tool based on a game theoretic model, called defensive forecasting, which can detect network intrusions in real time. The tool, by playing a “game” of reality versus forecast, wins when reality matches its forecast and it sends out an alert to block the intrusion.

Importantly, the tool works on real-time data flowing in and out of the network rather than analyzing logs, an approach that can only detect network intrusions after they have taken place. The game theoretic model continuously trains the tool so that it can recognize the patterns of typical network attacks: denial of service attacks, such as a syn flood, unauthorized access from remote machines in which login passwords are being guessed or brute-force tested, attacks by insiders with “superuser” or system root privileges or probing attacks in which software carries out surveillance or port scanning to find a way into the system.

In order to measure the effectiveness of the tool, Shin compared the approach using the semi-synthetic dataset generated from raw TCP/IP dump data by simulating a typical US Air Force LAN to a network intrusion system based on a support vector machine (SVM), which is considered one of the best classification methods for network intrusion detection. Experimental results show that the tool is as good as or better than the one based on SVM for detecting network intrusion while the tool adds the benefit of real-time detection.

How to Choose the Best Desktop Computer Monitor Stand

Purchasing a desktop computer monitor stand may seem like a pretty straightforward choice; after all, it’s just a simple inexpensive tool to support your computer monitor. However, you cannot highlight the importance of a monitor stand based on its price, as this little peripheral forms an essential part of your workstation or entertainment system, housing probably the most expensive piece of equipment in the system; the monitor.

So how should you choose the best monitor riser for your computer? Let’s find out.

Build Quality and Material

The most important thing to look out for when selecting a monitor stand is the build quality. The stand should have no flex whatsoever, and should be strong enough to support the monitor’s weight. Besides the flex, there should be no creaking sounds when you fit the monitor onto the stand. This is a sign that the stand is made of poor quality material, which would give way sooner or later.

Also important to note is the material that the stand is made from. Though most monitor arms are made of plastic or other non-magnetic materials, some manufacturers may also use electromagnets for electrical components such as a USB charging port. While you may think this is more “bang for your buck”, the circuitry’s magnetic field can interfere with the electrical components of the monitor, causing more harm than good.

If you are considering a monitor stand with power outlets, make sure the components generate low magnetism. This can be checked with a measuring device, or more conveniently with common household items such as a compass.

Adjustability

This is especially important if you use an LCD monitor, which has relatively narrow viewing angles. Make sure you get an adjustable height monitor stand, with which you can change the monitor’s altitude from the mounting point. It would also be preferable to get one with an adjustable horizontal swivel as well, though this isn’t as common. The manufacturer usually provides a swivel for adjustable height monitor stands, though more expensive monitor riser may also use electronic controls.

Mounting Options

Next on the list are the mounting options of the stand. There should be a hole in the back of the stand in case of a wall mounting option, though more common are mounts at the bottom of the stand, which keep the monitor in place during use. The former is something you should consider if you plan on using your monitor as part of a home entertainment system.

Color

Though this isn’t as important as the above, it is still something you should consider, as the monitor stand should match its surroundings. This makes the system look aesthetically pleasing, as the stand would fit in with the rest of the equipment.

Cooling a Server Room the Cost-Efficient Way

As the servers are used constantly, they generate tremendous heat. When this heat increases beyond control, it may lead to damage of the devices and equipment. Being machines, the computers are delicate under the hood and are prone to damage due to carelessness. System crashes, reboots, hang-ups, untimely failures; poor performance and other problems can be created due to abnormal temperatures. Now, one way to keep these issues under control is to maintain the server room’s temperature. Sufficient ventilation, cooling and maintained temperature are the efficient ways to protect computers and servers.

Maintaining the temperature

The computers used at homes and for small offices come with internal cooling devices, which usually keep the desktops and laptops cool. Nevertheless, the server rooms that manage a number of systems do not have sufficient internal cooling systems. They have to be kept cool using an external cooling source, such as portable air-conditioner. Secondly, increased humidity inside the enclosed area can cause corrosion or rust. The maximum humidity level of a server room should not exceed 40 to 50 percent.

Are portable air conditioners good solutions for cooling?

The temperature of the server room should be steadily cool around-the-clock. If the room or storage area is connected to the central cooling systems, they may be shut down during the weekends or sometime late at night, depending upon the company’s working hours. If the cooling systems fail, the computer systems are prone to face the brunt.

Portable air-conditioners keep the server rooms cool, as the temperature can be controlled individually depending upon the outside temperature. There are few air-conditioners that adjust the temperature according to the outside temperature on certain modes. They are self-contained units which do not require permanent installation. Business owners can move these units anywhere as required.

A portable AC used in such places must have condensation tank to manage the humidity level, automatic restart function and proper ventilation to replace the hot air inside the room. These features not only keep the servers cool but also regulate fresh air and keep the machines working continuously. The automatic function keeps the air conditioners working continuously even when there is a power cut or failure.

When it comes to the size of the air conditioners it is never an issue. The server closet of size 9000 to 12000BTU will be sufficient for the unit to fit in. While a 12K BTU unit requires 9 to 12 amps a huge unit of 14000BTU requires 20 amps. The air-conditioner should be thoroughly checked for the necessary requirements before installation.

Fix A Computer That Will Not Find A Keyboard, In No Time At All

Perplexed with trying to fix a computer that will not find a keyboard?

Frustrating, isnt it.

Already tried re-installing the device driver?

Checked that the hardware is in full working order?

Checked the cables and connections to the PC?

Cleaned your keyboard thoroughly?

If you answered yes to all of the above, we may just have the solution for you.

Your problem is likely to reside in your Windows registry.

You see, your registry acts very much like an instruction manual to your computer; telling it how to perform certain tasks and applications successfully without interruption. This includes the proper functioning of your keyboard.

When a registry entry becomes corrupt or redundant for one reason or another, it means that your computer can no longer understand the instructions that it is being given and as a result, the respective piece of hardware or software that the corrupt instructions relate to, fail to work properly.

This is one of the most common causes of keyboard failure. Yet it is also surprisingly easy to fix a computer that will not find a keyboard.

Uninstalling and re-installing the device driver for your keyboard can prove ineffective in this instance, given that the uninstall feature often fails to remove all of the instructions from the registry; leaving the problem to remain and subsequently re-appear upon re-installation of the device driver.

You must therefore go further than a simple uninstall procedure and get deep into your registry to clean out all corrupt and invalid entries; leaving it clutter, and more importantly, error free.

For this you must use specialized registry cleaning software.

Registry cleaning software burrows deep into your Windows registry and weeds out all unnecessary and corrupt entries, displaying these to you in just less than 2 minutes. You will then be presented with the opportunity to remove these from your registry for good.

Once this has been done, you will be free to re-install your keyboard device driver and enjoy the ability to fix a computer that will not find a keyboard.

With so many registry cleaners on the market, and with it being of paramount importance that ALL corrupt entries are removed to allow for a fresh re-install of your keyboard device driver, we tested 10 of the most popular registry cleaning software packages on the market; bringing you the highest performing registry cleaner available.

Note: We are not, in any way, affiliated to any registry cleaning software. We performed this testing in order to give you, the user, an informed perspective when choosing your registry cleaning software package.

In our independent testing, one cleaner was the highest performer, scoring a hugely impressive 5 out of 5 in terms of registry repair skills, and an outstanding 4.5 out of 5 in the overall test. This positioned the registry cleaner as number 1 amongst all 10 registry cleaners tested.

Microsoft releases new Internet Explorer 9 browser

Microsoft released the latest version of its Internet Explorer web browsing software free online late Monday, hoping to fend off recent challenges by Firefox and Google Chrome. -IE9 has just released around the world,- a booming voice told a cheering crowd at 11:00 pm Monday (0400 GMT Tuesday) in the Austin City Limits Live concert hall where a launch party was being held. Internet Explorer 9 (IE9) was available for download in 30 languages at Fun4masti -Things are about to change,- Microsoft corporate vice president Dean Hachamovitch said just hours earlier at a press conference at the South By Southwest Interactive technology festival here. -We took a dramatically different tack,- he continued. -It’s a really good day for the Web.-IE9 is built to make the most of Microsoft’s latest operating system, Windows 7, as well as graphics processing chips that can power videos, games and graphics. The long list of partners that have adapted websites to IE9 includes Facebook, Twitter, Pandora, Hulu, and Yahoo!, according to Microsoft. -We have worked with partners reaching a billion active Internet users,- Hachamovitch said. -All of these partners are using IE9 to make a more beautiful Web, starting today.- More than 40 million copies of IE9 have already been downloaded as part of the process leading up to its official release, according to Microsoft. Microsoft showed off a lean, muscular new Internet Explorer crafted to spotlight slick websites and beat back competition from Firefox and Google. Microsoft director of web services strategy Ari Bixhorn booted up an Apple MacBook Pro laptop running the latest version of Firefox for a side-by-side comparison. A laptop powered by Windows and using IE9 smoothly zipped through cascading images illustrating top tunes at a radio station website while the competition appeared to be much slower. Once a website is reached, the IE9 browser seems to almost vanish to spotlight the content. -The browser is the stage and the websites are the stars of the show,- Hachamovitch told AFP during an earlier demonstration. The browser is included in Windows software, and the operating system remains at a core of Microsoft’s software empire. The Redmond, Washington-based technology colossus claims more than one billion Windows customers. IE9 promised to be another hit release for Microsoft, which has had market success with the Windows 7 operating system and the Kinect motion-sensing controller accessory for Xbox 360 video game consoles.
