What are Intrusion Detection Systems?

Intrusion Detection System (IDS) are becoming a very important part of any strategy for enterprise security. But what are Intrusion Detection systems? CERIAS, The Center for  Education  and Research in Information Assurance and Security, defines it this way: "The purpose of an intrusion detection system (or IDS) is to detect unauthorized access or misuse of a computer system. Intrusion detection systems are kind of like burglar alarms for computers. They sound alarms and sometimes even take corrective action when an intruder or abuser is detected. Many different intrusion detection systems have been developed but the detection schemes generally fall into one of two categories, anomaly detection or misuse detection. Anomaly detectors look for behavior that deviates from normal system use. Misuse detectors look for behavior that matches a known attack scenario. A great deal of time and effort has been invested in intrusion detection, and this list provides links to many sites...

Operating Mutual Funds - how these profit exploding money makers actually work

Although investing in  mutual funds  isn't the type of subject associated with wild parties and celebrations - it is something the serious investor should consider as a way of increasing their total worth. "But what EXACTLY is a  mutual fund " I hear you ask - "how does it work, who does what and how much do they cost?" Hang on, slow down - one question at a time please. What exactly is a mutual  fund ? Mutual  funds  are sold in shares to the public, allowing them to own different percentages of the fund depending on the amount they invest. Pay more = own more. Own more = get more $$ back again (theoretically) Simple. Stocks, bonds,  money market securities  and the like are purchased through the assets of these mutual funds in the financial markets. Shareholders indirectly own the assets held in the mutual fund, but the fund is guided by the  investment company  that finds the best way to earn the biggest return. (Indirec...

Tips For Cooking The Best Fajitas

Fajita is generally beef, chicken, pork or shrimp grilled and served on a flour tortilla with condiments. The chicken is worked with onions and  bell peppers . Fajita is served to the table sizzling loudly on a metal platter with tortilla and condiments on the side. Making your lips watery? Texans would love to take credit for giving the world fajitas but the honor goes to south of the border, Vagueros, who learnt the art of cutting tough beef into skirt steak. Fajitas are basically Tex  Mex dishes. Nowadays Fajita is almost anything cooked and wrapped in a flour tortilla. Only true fajitas are skirt steak. The preparation of Fajitas starts with marinating the beef using limejuice to tenderize at least for 24 hours. Well, there are no set rules for marinating; you can use your creative sense for that, but don't forget to use limejuice. To marinade beef or chicken, you can use the Ass Kickin Soakin' and Grilling Sauce. This would bring a true Mexican flavor. Fajitas are r...

Nanotechnology

As the horizons of  technology  expand, the real world is shrinking into a  Global  Village;  Nanotechnology  is the new area of interest in technology. Nanotechnology is an umbrella term that covers many areas of research dealing with objects that are measured in nanometers or billionth of meter. It is a hybrid science combining engineering and chemistry. The goal of nanotechnology is to manipulate atoms individually and place them in a pattern to produce a desired structure. Nano-sized  machines  called assemblers, that can be programmed to manipulate atoms and molecules at will, would be used to build  consumer  goods. Some nanomachines called replicators, would be programmed to build assemblers. Nanotechnology would enable creation of new generation of computer  components  with enormous storage capacity. But the greatest impact of nanotechnology could be the medical industry . Patients would drink fluids containing na...

The Influence Of Blues Guitar On Modern Music

Anybody interested in modern music sooner or later asks the question, "Where did it begin?" Well, if you leave blues  guitar music out, you will not have much of an answer. So let us look at where the blues came from, where it went and who it met on the way. We will also take a look at the "blues guitar sound" and how it has its unique effect on our feelings. The blues as a musical phenomenon began around 1911 when W.C. Handy published popular  songs , notably "Memphis Blues" and "St Louis Blues", which affected the hearts and souls of the black people. By the nineteen twenties the general population were beginning to hear this  new music  through its influence on jazz . Early blues singers like Bessie Smith and Billie Holiday sang with jazz  bands  while others played with "jug bands" accompanied by fiddle, kazoo and washboard. Of course to people like W. C. Handy who were brought up singing in church, the piano was the natural ins...

Stock Market - What's in a Trading Edge

Image
Unless you are able to develop a considerable trading edge over the other traders, you will end up losing your money, even if you are disciplined and organized. In this article, I discuss some elements that I use in my trading edge. Fundamental Analysis Fundamental analysis is the process of evaluating the financial condition of a company using financial reports, price/earning ratios, revenues, market share, sales and growth, etc. This type of analysis can be time consuming so instead of going through pages of financial reports, I simply look at IBD ratings. I like to use Investor's Business Daily (IBD found at investors.com) to get a quick overview of a stock. The IBD rating covers: 1 -  Earnings Per Share  (EPS) rating: tells me a stock's average short term (recent quarters) and long term (last three years) earning growth rate. The number I see is how the company compares to all other companies. The scale runs from 1 to 99, 99 being the best. 2 - Relative Price Str...

PSP2 may pack an OLED touchscreen and 3G, to be announced in three days

Image
I think that all PSP gamers will agree that it’s time we get a next generation portable console. The original PSP is more than 5 years old now and it seems its life-cycle will come to an end this year. A PSP2 concept The latest rumor reveals the PSP2 will pack an OLED touchscreen and 3G capabilities in addition to the Wi-Fi support. There will be no phone service though. It’s unclear whether the PSP2 will have model variations (such as Wi-Fi-only, 3G+Wi-Fi). As the rumor has it, Sony will announce the PSP2 at a special press-conference on 27 January. The premiere should come later on in 2011 with Japan probably the first country to get it. This is another  confirmation  that the PSP2 announcement will take place even before the PSP phone a.k.a. XPERIA Play, which is expected to be unveiled in early February at the MWC.

Best Running Shoes For Flat Feet

People were born with different physical characteristics in their bodies. With regards to feet considerations, you may be blessed (or cursed) to have a  flat foot . In accordance with this aspect of biological uniqueness, the  best running shoes  for flat feet should be used for optimum comfort and convenience. What is a flat foot? Having a flat foot can sometimes be a frustration in searching for the appropriate accessory, like  shoes . A flat foot is characterized by your foot print looking like a blob contoured in the general shape of a foot. You can easily check this using a footprint on a piece of paper. Also, physically, you may observe that there is almost no curve going inward from your toe to your heel. Another significant characteristic is that when you press firmly on any surface, your foot seems to spread out. What shoes to use? Shoes are generally created to provide protection to a person's feet. However, even though most of the commercially avai...

Linux or Windows - Which is it?

Computer users and programmers have become so accustomed to using  Windows , even for the changing capabilities and the appearances of the graphical interface of the versions, therefore it has remained Microsoft's product. Although, Lycoris,  Red Hat , Mandrake, Suse, Knoppix, Slackware and Lindows  make up  some of the different versions of  LINUX . These companies release their own versions of the operating systems with minor changes, and yet always with the same bottom line. The simple fact that not one of these companies are close to competing with Windows, for the most part causes the difference in  market share . It sometimes seems everyone on the planet is using Windows. Many say Windows is way better than LINUX because of the simple handling of the software or hardware. There are huge differences between the number of users of LINUX and Windows. Many say LINUX is far better because it started as an Open Source software and thus is more flexible th...

"Food Of The Future," 40 Years In The Making

Forty years ago, a first-class stamp cost a nickel, a new science fiction television show called "Star Trek" made its debut and a tasty topping began its crunchy history of enhancing salads, baked potatoes and Americans' cupboards. General Mills first tested Bac-Os as a better-for-you alternative to bacon in select markets in 1965. Bit by bit, the product's popularity took off, and it was dubbed a "food of the future" in early television advertisements. Consumers enjoyed the convenient product's multipurpose use-a savory ingredient used to jazz up casseroles, salads, soups and other favorite dishes. This handy condiment helped home cooks streamline their kitchen prep and promised the smoke-cured, sizzling flavor of bacon without a splattering mess. "A jar of Bac-Os brought the flavor and texture of crisp bacon right to the family dinner table in a fraction of the time," says Maggie Gilbert, manager of the Betty Crocker Kitchens test kitchen...

5 Reasons to Choose a Notebook Over a Computer Desktop

Many of us are so used to working on a  computer desktop  that when it comes time to purchase a new computer, we don't consider other options. Today, computer  notebooks  - which were once called laptops - offer a number of advantages over a computer  desktop . Here are just five reasons why you should take a second look at notebooks. 1. Mobility You might be used to pulling up a chair to your computer, but it makes much more sense to pull your computer up to your chair. Laptops can certainly be used at your desk, but you also have the option of bringing them to the spot where you're most comfortable. Maybe you'd like to surf the Web in the evening out in the living room or catch up on your favorite blogs before bedtime. Notebooks with wireless connectivity can travel with you throughout your home, so you can check your email or do your Internet shopping anywhere. Of course, notebooks also make sense for those who are on the go. Students can take laptops t...

Intel starts 2011 with a bang: 29 new Sandy Bridge CPUs are here

Image
Intel used the first workday of 2011 to announce a fresh lineup of Core processors. The second generation of i3, i5 and i7 chips uses the Sandy Bridge architecture and so far includes no less than 29 CPUs. All the new Intel processors are based on 32nm manufacturing process and boast improved performance plus better power efficiency. And it’s not just the reduced-size instructions that lead to it – according to Intel it’s also due to the L3 cache, which is now shared between all cores. The new CPUs come with built-in HD 2000/3000 graphics that promise a 2x improvement in performance compared to their predecessor. That’s still not matching a discrete GPU, but it’s not like everyone actually needs so much graphics power. Early reviews say that the new Intel graphics are even good enough for gaming if you can live with the lowest detail settings. The Turbo boost technology was also improved in the latest generation of Intel chips. It now allows for even higher clock speeds...

Samsung finishes the development of the world’s first DDR4 DRAM

Image
Although DDR4 DRAM is not expected to be in anyone’s computer system until the beginning of 2012, Samsung is already done developing it. The new DDR4 modules will not only be faster than their DDR3 predecessor, but they are going to run using less power as well. In order to accomplish the lower power consumption of the modules, Samsung is using the 30nm-class process technology. Now you may be wondering how much faster the new DRAM is compared to the current DDR3. We can’t know for sure, until the production of actual units starts, but here are some initial figures for you. The speed of data transfers that DDR4 DRAM can achieve is 2.133Gbps (gigabits per second) at 1.2V, compared to the DDR3 DRAM, which can only pump out 1.6Gbps at either 1.35V or 1.5V. The modules make use of a new circuit architecture, which helps them make the jump from 1.6Gbps all the way up to 3.2Gbps. This is tremendous improvement compared to the usual speeds of 1.6Gbps and 800Mbps for DDR3 and ...

Android Task Killers Explained: What They Do and Why You Shouldn't Use Them

Image
Android task killers improve your phone's performance while also boosting battery life—or at least that's the much-debated promise. Here's a look at how task killers actually work, when you should (or shouldn't) use them, and what you can do instead. A task killer is an app from which you can (sometimes automatically) force other apps to quit, the hope being that the fewer apps you have running in the background, the better your Android's performance and battery life will be. Not everyone agrees with this premise, though. The argument about whether task killers are effective rages all over the internet: Android forums are full of threads with constant bickering and conflicting anecdotal experience, making it difficult for most users to make sense of the situation. Below, I'm going to dig into the truth about Android task killers: that apart from maybe some older phones, Android manages tasks fairly well on its own, and how task killers present qu...

How and Why Chrome Is Overtaking Firefox Among Power Users

Image
Firefox has long been the go-to web browser among power users for its impressive feature set, extensibility, and openness. But Google's nimble, light, also extensible and open browser, Chrome, has won over Firefox's core user base. Here's why: On Monday, we asked Lifehacker readers to share their current browser of choice , and the results were surprising. While we'd expected to see a jump in Chrome usage since our last poll (in which Firefox was favored by 57 percent of respondents to Chrome's 21 percent), we didn't expect Chrome to have surpassed Firefox usage by almost 10 percent. Specifically, out of 40,000 responses, 42 percent chose Chrome as their browser of choice; 33 percent chose Firefox. We've championed Firefox at Lifehacker HQ since we opened our doors back in 2005, and we may never be able to adequately express the love we feel toward Firefox for rescuing us from the clutches of Internet Explorer. But if our poll is any indicatio...

Top 10 Things to Do with a New Windows 7 System

Image
Whether you've just bought a new PC, upgraded to Windows 7, or reinstalled your OS , a just-installed system is a great opportunity to make some helpful changes and fixes. Here are the things we recommend anyone tackle on a minty fresh Windows. We've previously rounded up the bulk of our Windows 7 advice, from first installation to fine detail tweaking, in our complete guide to Windows 7 , as well as packaged our favorite little utilities and customization apps in a list of 10 booster apps . This guide, in contrast, doesn't include many downloads, and focuses on what one can do to fix up their system from the get-go, no separate app required. 10. Change Up Your Theme Unlike its predecessors, Windows 7 offers a lot of non-hacker-ish ways in which you can change the entire look of your desktop, not just the wallpaper. We took an early tour of Windows 7's many free and legit themes , and noted that Microsoft checks in occasionally to provide more themes at its s...
