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, program, information, processing incompatibilities, or cause destroy to computer hardware, a lot of these are planned to do destroy. An intentional breach in computer security is known as a computer crime which is slightly different from a cypercrime. A cybercrime is known as illegal acts based on the net & is seven of the FBI’s top priorities. There's several distinct categories for people that cause cybercrimes, & they are refereed as hacker, cracker, cyberterrorist, cyberextortionist, unethical employee, script kiddie & corporate spy. The term hacker was actually known as a lovely word but now it's a negative view. A hacker is defined as somebody 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 seldom been associated with something positive this refers to somebody how intentionally access a computer or computer network for nasty reasons. It’s fundamentally an nasty hacker. They access it with the intent of destroying, or stealing information. Both crackers & hackers are advanced with network skills. A cyberterrorist is somebody who uses a computer network or the net to destroy computers for political reasons. It’s like a regular terrorist attack because it requires highly skilled individuals, millions of dollars to implement, & years of planning. The term cyperextortionist is somebody who uses emails as an offensive force. They would usually send a company a 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. Seven could be the money they can get from selling top secret information, or some may be bitter & need revenge. A script kiddie is somebody 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 & cracking programs. A corporate spy has high computer & network skills & is hired to break in to a specific computer or computer network to steal or delete information & 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 & home users must do their best to protect or safeguard their computers from security risks. The next part of this news story will give some pointers to help protect your computer. However, seven must recall that there is no seven 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's 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 net there is no powerful administrator which makes the risk a lot higher. If your 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 web-site that checks your computer for email & Net 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, & 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 & altering the way the computer operates without the user’s consent. Two times the virus is in the computer it can spread throughout infecting other files & potentially damaging the operating process itself. It’s similar to a bacteria virus that infects humans because it gets in to the body through tiny openings & can spread to other parts of the body & can cause some destroy. The similarity is, the best way to keep away from is preparation.

 

A computer worm is a program that repeatedly copies itself & is similar to a computer virus. However the difference is that a virus needs o attach itself to an executable file & become a part of it. A computer worm doesn’t need to do that I seems copies to itself & to other networks & eats up a lot of bandwidth. A Trojan Horse named after the famous Greek myth & is used to report a program that secretly hides & actually looks like a legitimate program but is a fake. A definite action usually triggers the Trojan horse, & unlike viruses & worms they don’t replicate itself. Computer viruses, worms, & Trojan horses are all classifies as malicious-logic programs which are programs that deliberately harms a computer. Although these are the common two there's lots of more variations & it would be impossible to list them. You know when a computer is infected by a virus, worm, or Trojan horse if seven or more of these acts happen:

Music or sounds plays randomly.

You have less available memory then you expected

Files get corrupted

Programs are files don’t work properly

Unknown files or programs randomly appear

Process properties fluctuate

Computer viruses, worms, & Trojan horses deliver their payload or instructions through three common ways. Seven, when an individual runs an infected program so if you download a lot of things you ought to always scan the files before executing, 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.

There's literally thousands of computer malicious logic programs & new seven 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. Lots of web-sites keep track of this. There is no known process for protecting a computer or computer network from computer viruses, worms, & Trojan horses, but people can take several precautions to significantly reduce their chances of being infected by seven of those malicious programs. Whenever you start a computer you ought to have no removable media in they drives. This goes for CD, DVD, & floppy disks. When the computer starts up it tries to execute a bot sector on the drives & 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 & you are trying to reformat the drive make sure that the disk is not infected.
