Computer technology has made the fastest advancement in the field of modern scientific development. Along with computer technology, the information technology has also made advances that were not possible about twenty years ago. The computer has made life easy for the common man. More and more people depend on the computers to do homework, work and create or store useful information and items which can be used later, or even corrected at some other stage. Thus it has become all the more important to keep safe the information that has been stored in your computer from misuse or being stolen. Also it is extremely important to protect our computers from data loss, misuse and abuse.
For example, it is crucial for businesses to keep information they have secure so that hackers can’t access the information. Home users also need to take means to make sure that their credit card numbers are secure when they are participating in online transactions. A computer security risk is any action that could cause lost of information, software, data, processing incompatibilities, or cause damage to computer hardware, a lot of these are planned to do damage. An intentional breach in computer security is known as a computer crime which is slightly different from a cybercrime. A cybercrime is known as illegal acts based on the internet and is one of the FBI’s top priorities. There are several distinct categories for people that cause cybercrimes, and they are refereed as hacker, cracker, cyberterrorist, cyberextortionist, unethical employee, script kiddie and corporate spy.
The term hacker was actually known as a good word but now it has a very negative view. A hacker is defined as someone who accesses a computer or computer network unlawfully. They often claim that they do this to find leaks in the security of a network. The term cracker has never been associated with something positive this refers to someone how intentionally access a computer or computer network for evil reasons. It’s basically an evil hacker. They access it with the intent of destroying, or stealing information. Both crackers and hackers are very advanced with network skills.
A cyberterrorist is someone who uses a computer network or the internet to destroy computers for political reasons. It’s just like a regular terrorist attack because it requires highly skilled individuals, millions of dollars to implement, and years of planning. The term cyperextortionist is someone who uses emails as an offensive force. They would usually send a company a very threatening email stating that they will release some confidential information, exploit a security leak, or launch an attack that will harm a company’s network. They will request a paid amount to not proceed sort of like black mailing in a since. An unethical employee is an employee that illegally accesses their company’s network for numerous reasons. One could be the money they can get from selling top secret information, or some may be bitter and want revenge.
A script kiddie is someone who is like a cracker because they may have the intentions of doing harm, but they usually lack the technical skills. They are usually silly teenagers that use prewritten hacking and cracking programs. A corporate spy has extremely high computer and network skills and is hired to break into a specific computer or computer network to steal or delete data and information. Shady companies hire these type people in a practice known as corporate espionage. They do this to gain an advantage over their competition an illegal practice.
Business and home users must do their best to protect or safeguard their computers from security risks. The next part of this article will give some pointers to help protect your computer. However, one must remember that there is no one hundred percent guarantee way to protect your computer so becoming more knowledgeable about them is a must during these days. When you transfer information over a network it has a high security risk compared to information transmitted in a business network because the administrators usually take some extreme measures to help protect against security risks.
Over the internet there is no powerful administrator which makes the risk a lot higher. If you are not sure if your computer is vulnerable to a computer risk than you can always use some-type of online security service which is a website that checks your computer for email and Internet vulnerabilities. The company will then give some pointers on how to correct these vulnerabilities. The Computer Emergency Response Team Coordination Center is a place that can do this.
The typical network attacks that puts computers at risk includes viruses, worms, spoofing, Trojan horses, and denial of service attacks. Every unprotected computer is vulnerable to a computer virus which is a potentially harming computer program that infects a computer negatively and altering the way the computer operates without the user’s consent. Once the virus is in the computer it can spread throughout infecting other files and potentially damaging the operating system itself. It’s similar to a bacteria virus that infects humans because it gets into the body through small openings and can spread to other parts of the body and can cause some damage.
The similarity is, the best way to avoid is preparation. A computer worm is a program that repeatedly copies itself and is very similar to a computer virus. However the difference is that a virus needs o attach itself to an executable file and become a part of it. A computer worm doesn’t need to do that I seems copies to itself and to other networks and eats up a lot of bandwidth.
A Trojan horse named after the famous Greek myth and is used to describe a program that secretly hides and actually looks like a legitimate program but is a fake. A certain action usually triggers the Trojan horse, and unlike viruses and worms they don’t replicate itself. Computer viruses, worms, and Trojan horses are all classifies as malicious-logic programs which are just programs that deliberately harms a computer. Although these are the common three there are many more variations and it would be almost impossible to list them. You know when a computer is infected by a virus, worm, or Trojan horse if one or more of these acts happen:
- Screen shots of weird messages or pictures appear.
- You have less available memory then you expected
- Music or sounds plays randomly.
- Files get corrupted
- Programs are files don’t work properly
- Unknown files or programs randomly appear
- System properties fluctuate
Computer viruses, worms, and Trojan horses deliver their payload or instructions through four common ways. One, when an individual runs an infected program so if you download a lot of things you should always scan the files before executing, especially executable files. Second, is when an individual runs an infected program. Third, is when an individual bots a computer with an infected drive, so that’s why it’s important to not leave media files in your computer when you shut it down. Fourth is when it connects an unprotected computer to a network. Today, a very common way that people get a computer virus, worm, or Trojan horse is when they open up an infected file through an email attachment.
There are literally thousands of computer malicious logic programs and new one comes out by the numbers so that’s why it’s important to keep up to date with new ones that come out each day. Many websites keep track of this. There is no known method for completely protecting a computer or computer network from computer viruses, worms, and Trojan horses, but people can take several precautions to significantly reduce their chances of being infected by one of those malicious programs.
Whenever you start a computer you should have no removable media in the drives. This goes for CD, DVD, and floppy disks. When the computer starts up it tries to execute a bot sector on the drives and even if it’s unsuccessful any given various on the bot sector can infect the computer’s hard disk. If you must start the computer for a particular reason, such as the hard disk fails and you are trying to reformat the drive make sure that the disk is not infected.

One of the hottest gadgets today is the Apple iPhone. There are many reasons for buying the iPhone. One of this reason is that we can stay connected with our friends, family and business contacts, send emails, surf the internet and do a host of other things that is not possible with an ordinary cell phone. There is another great feature of the iPhone. That feature is the 2.0 Megapixel Camera that is attached to the phone.
Just as you have to take care of your electronic devices, you should also take care of your iPhone so that it can give you the best of services for many years to come. Some people may think that the best of taking care of their iPhone is to purchase some products for keeping if safe. But this is not so. The most important of taking care of your iPhone is simply to clean it thoroughly. There may be some problems because the screen of the iPhone is very sensitive to touch and very few persons know the correct way of cleaning their iPhone.
There are quite a number of benefits of owning an Apple iPhone. Not only are there benefits, but you can add a number of applications also to this phone. Gone are the days of the bulky electronic items with the coming of the iPhone. Now, with your iPhone, you can listen to your favorite songs, check your e-mail, get directions and have constant contact with the world around you. Yet, one of the greatest features about the iPhone is the fact that it has the most up-to-date Bluetooth technology placed inside of its frame. Bluetooth is a great way to add even more portability and easy access to your iPhone and the contacts within it. But what is the best Bluetooth device for your iPhone?
h Apple, you used to be so cool with your mobile computing platform and your ubiquitous application store. Now, everyone has gone and shown up to the Mobile World Conference in Barcelona and announced their own application store for their own mobile computing platform. Now, instead of the just the Apple iTunes App store, there are going to be no less than seven application stores for seven different mobile platforms.
I’m not sure how it’s going out there in the big ol’ US of A, but over here in the UK prices for cameras are going bananas, literally. The pound has devalued significantly, and as such, with a lot of cameras imported from america, and as such, something like the Canon 580ex mk flash unit, has literally doubled in price up to £500. Loads of other things have gone up, lenses, bodies, the lot. I was planning an upgrade before christmas but now…..I just can’t afford it! Can anyone in the US tell me if things have changed at all for you?
In any event, performing digital signal processing using organic and chemical materials without electrical currents could be the wave of the future – or so argue Sotirios Tsaftaris, research professor of electrical engineering and computer science, and Aggelos Katsaggelos, Ameritech Professor of Electrical Engineering and Computer Science, in their recently published “point of view” piece in the March 2008 edition of Proceedings of the IEEE (Institute of Electrical and Electronics Engineers.)
Astonishing breakthrough. Household object. Funny anachronism. Such is the journey that nearly every great gadget travels. And then it happens all over again with whatever hot new gizmo rendered the old one obsolete.
