Computer security and encryption becoming more vital

One of the greatest miscalculations a business owner can commit is by not prioritizing how he will protect his computer system from unauthorized intrusions and data theft.

There is a common belief among business owners especially those that do not operate a big business that their small size makes them safe from the malicious intent of computer phreakers and data thieves. They think that in a sea full of big fishes a small fish will be ignored, secure in the fact they are not worth the exertion and computer time for notorious data thieves.

Nothing can be farther from the truth. In fact, smaller businesses are far more vulnerable to internet security threats and all manner of data theft and electronic sabotage. Based on a study made by research firm AMI-Partners, almost half of all small and medium sized businesses have failed to implement even the most rudimentary security precautions – which includes the installation of antivirus and anti spyware programs. This oversight could be the main reason why when the Mydoom worm hit a few years back, one in three small and medium sized businesses were affected compared to just one in six among the larger companies were affected. This was discovered by the Internet Security Alliance, a non profit organization that deals with information security issues.

In fact, now more than ever data and network protection should be given more attention because of the ever evolving sophistication of data thieves. They are now more equipped with the software and hardware necessary to break into security measures instituted by data managers. What could the chance be for a company to weather an attack if the owner forgets or ignores putting in place data security and encryption policies for his business because he thinks it will just be an additional cost? Practically zero and the untold cost to his business would be far more greater.

It is for this reason that data security and encryption should be one of the priorities of a business. Anyone is vulnerable to an attack whether that business is an international conglomerate or a new start up. In fact, a big business will have more chance to recover compared to a small business because a big company will have the read funds available to rebuild the business. A small business, on the other hand, will not have the necessary funding to start the business all over again – making an attack quite catastrophic.

These facts are not lost on many software providers who are now coming up with many types of solutions that guarantee the safety of data in an office’s network. There are also software that bring security to a higher level by incorporating encryption technology in order to safeguard not only sensitive data but also to make it harder for hackers to get into networks or intercept data being transmitted from the corporate network to devices outside of the network. Encryption technology can, in fact, be seen as one of the highest levels of protection that a business can employ in order to ensure the integrity of its data and its computer network.

Computer Security: Threats and Solutions

When it comes to computer security, many of us live in a bubble of blissful ignorance. We might be vigilant and never open email attachments from people we don't know, we might take care to make sure an ecommerce site is secure before entering our credit card information, or we might even go so far as to install a standard firewall on our computers. Unfortunately, much of the common sense advice we follow when it comes to Internet security does little to combat the cyber-crime that is rampant.

Federal Trade Commission

Even the U.S. Federal Trade Commission, a governmental agency that is designed to help consumers, had to issue a press release stating that "consumers, including corporate and banking executives, appear to be targets of a bogus e-mail supposedly sent by the Federal Trade Commission but actually sent by third parties hoping to install spyware on computers."

There's little doubt that spyware, malware, and insidious virus attacks make any computer with Internet access vulnerable. But, because not all Internet security breaches are immediately apparent, people are often unaware that their seemingly hassle-free computing is anything but. The Federal Trade Commission offers seven guidelines to help consumer surf the Web safely:

1. Protect your personal information. For example, when shopping on an ecommerce site, make sure that the page where you enter your personal information is secure, as designated by "https" before the URL. It's important to stop identity theft before it starts.

2. Know before you click. For instance, many cyber-criminals impersonate legitimate businesses, or send "phishing" email that asks you to click a hyperlink. Check out online merchants and never click on emailed hyperlinks unless you're certain of the source.

3. Update anti-virus, anti-spyware, and firewall software often. Hackers and others who engage in cyber-crime seem to always be a step ahead of the good guys. If your computer protection is outdated, you're vulnerable.

4. Use Web browser and operating system security features. Make sure your browser settings give you optimal privacy and security, and ensure that you update your operating system regularly to take advantage of security patches.

5. Safeguard your passwords. For example, create a unique password for each site you visit, and keep them in a secure place. Use letter, number and symbol combinations that can outsmart automated password detection programs.

6. Always do backups. If your computer does get a virus or a worm, your files may be goners. Make sure to regularly back up any important files and store them in a secure place.

7. Prepare for emergencies. If something does go wrong, such as your computer being hacked or infected, or if you accidentally divulge personal information, know what courses of action you should take to remedy the situation and prevent further problems.

A Hassle-Free Solution

Protecting your computer from all of the threats in cyberspace can seem like full-time job. Thankfully, there are companies who make it their business to offer individuals and businesses the most technologically advanced computer security solutions available. The best of these services offer PC maintenance, full system optimization, problem diagnosis and repair, installation assistance, and a full complement of professionally managed security services. Typically, you pay a small monthly subscription fee and in turn can surf the Web knowing that your computer is locked down and that you'll never again have to stay abreast of the latest security software or lug your computer down to a high-priced repair center.

Computer Security – It’s Bigger than Spyware and Viruses

Computer security, in basic terms means keeping your computer and the data that’s in it safe and secure. More of our personal data is stored in or accessed from our computer, now more than ever before. Yet most people lack even the basic understanding of how to keep their computers safe and secure. By following just a few simple rules you can dramatically improve the overall security of your computer.

The first thing to understand is what exactly it means to be connected to the internet. Your computer connected to the internet is similar to your house in many ways. There are many ways into your house. Windows, doors, etc. The more windows and doors you have, the more ways someone has into your house. An open door doesn’t necessarily mean you are going to be robbed, but it does improve the chances. Complicating matters, the ones that you think are locked, may not be because the lock is faulty or even the door itself may have an as of yet undiscovered flaw that would allow an intruder easy access to your home.

Your computer has many windows and doors, not all of which are locked. New flaws are being found everyday, often with the fix not coming until days after. Just like you wouldn’t leave your front door unlocked, you shouldn’t leave your computer wide open either. The first two things we will discuss to help with this task are installation of a quality firewall and regularly updating your installed software.

Updating your software is becoming easier these days, especially your Operating System. We don’t have the time here to go into detail about the many ways to update the many software packages you may have or use, but generally speaking the software manufacturer will provide you a way to do this automatically via the internet. A good example of this is the Microsoft Windows Update feature. Be sure to get the updates for everything installed on your computer, nothing is too trivial.

There are two basic types of firewalls and both perform the same functions. One is hardware the other is software. A hardware firewall is probably included in your router if you are using one, while you may or may not have a software firewall installed. To continue our house analogy, a firewall is like building a wall and gate around your home and giving the guard at the gate instructions on who to let in and out. While this does give a great deal of protection, it is not all that is required. Someone may know a way around or under your wall, or even be able to coerce the guard into letting them in.

You yourself may unwittingly allow someone in. This could happen by simply opening an email or even simply surfing the net. Spyware, viruses, trojans and the like are ever more adept in their methods of fooling you and your guards. Emails may come from a trusted friend containing a dangerous virus without them even knowing it. This is where the next layer of protection comes in, anti-virus software.

Anti-virus software is a large category these days. Often these packages come as “suites” including a firewall and Spyware scanner. While most of these programs are very effective in their promised tasks, it is not wise to be lulled into a false sense of security by them. They are simply one layer in what should be a multi tiered protection plan for you and your computer. One last important note about anti virus software is to be sure that it updates on a regular basis. New threats come out daily so check its updates manually to be sure they have happened.

Back to our house analogy, we now have all of our windows, doors and other entry ways locked and fully updated. We have a wall around our house with a guard at the gate and we have software scanning everything that comes in past the gate. Sounds pretty good, but there’s one last security hole we need to address, you.

A large percentage of infections are caused by the computer user themselves. The internet is an ever changing place that requires it’s users to be educated about its use. I’m not suggesting that you need to be a computer expert to simply read your email. I am however suggesting that you take some time to educate yourself on some of the dangers that pop up everyday, and the precautions to take in order to avoid them.

In summary, your computer is a powerful machine connected to one of the greatest things ever invented, the internet. This vast resource can be a dangerous place if you are not properly prepared and informed. Regular software updates, a good firewall, anti virus software and a little education are the basics in computer security. Having and understanding these basics will make your computer safer, more secure and more enjoyable.

Computer Repair Is A Tricky Business

Computer is a combination of analog and digital device which is used to compute complex mathematical problems. It is basically a programmable electronic device which performs high speed mathematical and logical operations. The main function of computer is to perform repetitive procedures very quickly and reliably.

The computer can be broadly divided in two sections; one is hardware and the other is software. The hardware is made of electronic circuits and components while the software is the programs required to run the central processing unit or the CPU. Again the hardware is of four type i.e. CPU, input, output and memory device. Now a days looking at the vast uses of computer people are using computer at their offices and at homes for working as well as entertainment purposes.

As we all know that each and every electronic goods need repairing and computer is not excluded from that list. Whenever there is any troubleshoot in this whole procedure the computer seems to function improperly. As a result we need to repair our computer to make it function properly. It is very tedious to repair ones computer and beside that it is also time consuming if the problem is unknown by the repairer. But if anyone has sound information regarding computer repair then it would seem to be rather easier. There are several organizations with trained and qualified technicians to help you out whenever you have problem with your computer. There are also various computer selling organizations who give after sell repairing service completely at free of cost. While there are other computers organizations, which have good computer technicians, provide only repairing service. Each of these companies serves their clients with best technical services. There are also different books or guidelines to provide us various information regarding computer trouble shoot and how to repair them. There are also technical colleges and training institute for technicians to learn more about computer problems and their repairing.

There are computers of various brands such as IBM, HP, Compaq, Dell, Apple etc. in the market and they differ from each other in respect of hardware and software. Therefore their troubleshooting problems also differ from each other. So the technicians should know how to repair these different computers. A good computer technician is required to familiar with various operating systems such as Microsoft Windows, Macintosh, Linux, etc. A good technician must also know how to deal with different computer peripherals such as printers, scanners, fax machines, etc.

Here are few troubleshoots of computers which are very common. They are 1) Power Supply Failure, 2) Motherboard Troubleshooting, 3) Hard Drive Failure 4), CD and DVD Drive Troubleshooting, 5) Modem Failure, 6) Sound and Game Card Failure, 7) Peripheral Failure 8) Virus Threats and many more. At first the technician need to do a complete diagnostic checkup. Then he needs follow those Basic Computer Repairing rules to repair a troubleshooting computer successfully. Beside these computer requires regular update, virus cleaning and modifications. At last we can conclude that if computers are maintained and handled properly then we can prevent our computers from various troubleshoots as we all know that 'prevention is always better than cure'.

Computer Repair

Owing a computer is almost essential in today’s world. With the introduction of the internet and the convenience of email as a method of communication, it’s easy to see why most people want to have a computer in their home or office.

Computers are like anything else and there are times when they don’t operate as planned. It’s frustrating to be sitting at your desk ready to play a game or work on a document only to find that your computer isn’t being cooperative.

When it comes to computer repair it’s often wise to seek out professional help. A computer technician is specially trained to evaluate the problem and offer the best possible solution.

There are certain types of computer repair that you might want to undertake yourself. These are usually minor fixes that can be handled with a bit of instruction and attention to detail.

A computer repair that you might be able to take care of yourself is the replacement of the computer’s battery or fan. Every desktop computer has a fan inside of it. This fan is used to keep the computer’s components cool. It’s essential that the fan operates efficiently to ensure that the computer doesn’t become overheated.

The first sign that your computer’s fan might not be operating properly is that you’ll notice a different sound when you start or run your computer. Instead of immediately taking it to a computer repair shop, take a moment to test the fan.

Computers typically have two fans. One is used to cool the power supply and the other is used to cool the CPU. Open the cover of the computer and listen. If the sound does appear to be coming from the fan that cools the CPU you’ll want to replace it.

If the computer is still under warranty than this type of computer repair will be done free of charge. Follow the instructions you were given for repairs at the time of purchase. If the warranty period has elapsed you can either take it to a computer repair shop or do it yourself.

The very first and most important step when doing any computer repair is to unplug the computer from the electrical outlet. You’ll then need to examine the fan to see how it’s connected. It will probably be attached by a few small screws. Once these are loosened you’ll need to disconnect the fan from its power supply. This will be one or two small clips. Then take the fan to your computer repair shop and purchase a new one.

After replacing it, reattach the cover and plug the machine in. The fan should operate perfectly now and the noise that you were hearing will have disappeared.

Sometimes a computer will make noises because a piece of hardware isn’t attached properly. One of the likely culprits is the CD-Rom or DVD drive. Again for this type of computer repair, you’ll want to carefully remove the cover and listen for the source of the noise. After tightening the screws that hold the hardware in place and reattaching the cover, plug the machine in and listen if the offending noise is gone.

When it comes to computer repair it’s important to be safe and thorough. Computers are an expensive investment and keeping them running efficiently is crucial. If you are comfortable handling a small computer repair yourself, give it a try. If you’re not comfortable, take the machine to a local computer repair shop and allow the experts to do their job.

Computer Rental: Worth Your Money?

Is computer rental worth the money? Depending on the type of computer that you have a need for as well as the expenses that you plan to save, computer rental may or may not be the right road for you to go down. One thing is quite certain. That is, there are a number of companies out there right now wanting to provide you with the computer rental that you are after. They offer a wide range of products and services. But, is it worth spending your money on these computer rentals? Or, maybe you should just outright make the purchase?

The value of the computer rental is dependent on the need that you have as well as the overall need you expect to have down the road. It makes sense that if you only plan to use the computers for a few days or weeks that you should consider the computer rental industry. Often times it is important to have a large group of computers ready to go but you really have no need for them after a certain point. This happens and it just makes complete sense to use computer rental services.

If you plan to rent a computer for a continuous time period, then it may just be well worth it to actually make the purchase. For example, many individuals find that computer rental is a low cost option to purchasing and owning a computer. For personal use, though, it makes very little sense as you will likely be able to find a PC at a much lower cost in the long run.

Regardless of your need of computer rentals, it makes good sense to shop around for the right deal. And, it also makes sense to get the exact computer that you need as well as a back up service should you need that as well. Computer rental is something that many corporations need and therefore it is important for services out there to satisfy their customer’s demands. Computer rental services can be found throughout the web as well as in most local areas.

Computer Recycling – Switch To Environmental Friendly Mode

Computer recycling refers to the practice of salvaging useable components from obsolete electronic devices or safely disposing off electronic devices. It is a practice that each one of us must inculcate because inappropriate handling of discarded computers and other electronic devices can cause environmental hazards.

Studies estimate that over 40 million electronic pieces become obsolete annually. These pieces have constituents such as lead, cadmium, barium, and mercury, which are hazardous to the environment. In a landfill, these materials seep into the ground and then into our food and water supplies. This can cause serious health concerns over a long period.

Obsolete Computers: Environmental Threats
Obsolete computers that are simply dumped in the garbage drums are the biggest threat to the environment. The computer monitors have cathode ray tubes containing four to five pounds of lead that contaminates the environment acutely. Besides lead, the computers have many other hazardous elements such as mercury, cadmium, and hexavalent chromium. When inhaled over a long period, these elements cause high blood pressure, liver and nerve disease, blood with poor iron, and even brain damage to the exposed group. This causes great concern, considering several million computers become obsolete annually.

Therefore, we must handle the obsolete electronic devices carefully. Moreover, different Environmental Laws have banned the illegal landfills by the disposals of computers and other electronic equipment. These laws necessitate sending the un-functional computers to a reputable recycler for harmless recycling. The laws also specify the need for regular recycling to avoid such computers from piling up.

There are several methods to deal with old computers. Some of them are as follows:

· Give It For Reuse: If your computer is in a decent condition, you can sell it to a company or an individual so that it can be used further, or simply donate it to someone needy.

· Trade It In: There are many computer dealers (e.g. HP) who offer trade-in promotions on computers and peripherals.

· Auction It: You can sell the computer on eBay or any other auction site. You can also organize a quick garage sale and see if any of your friends or neighbors wants the computer.

· Set up a Server: You can continue using the old computer as a server to store and share data.

· Salvage Some Parts: You can see which parts of your computers are in good working condition. You can salvage those parts and use them in your new computer.

Go for computer recycling and safe the planet earth!
