Today, many people rely on computers to do homework, work, and create or store useful information. Therefore, it is important that the information on the computer is properly stored and stored. It is also extremely important for computer people to protect their computer from data loss, misuse . For example, it is crucial for businesses to keep information safe and secure from hackers. Home users must also take measures to ensure that their credit card numbers are secure when engaging in online transactions. A computer security risk is any action that could cause loss of information, software, data, processing incompatibility, or cause damage to computer hardware, many of which are planned to be damaged. The intentional breach of computer security is known as cybercrime, which is slightly different from cybercrime. Cybercrime is known as illegal acts based on the Internet and is one of the top priorities of the FBI. There are several different categories for people who cause cyber crimes, and they are rated as hacker, cracker, cyberterrorist, cyber extortionist, unethical employee, screenwriter 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 gains unauthorized access to a computer or computer network. They often claim that they do this to find vulnerabilities in network security. The term cracker has never been associated with anything positive, referring to someone intentionally accessing a computer or computer network for nefarious reasons. He's basically an evil hacker. They access them with the intention of destroying or stealing information. Both crackers and hackers are very advanced with networking skills. A cyber terrorist is someone who uses a computer network or the Internet to destroy computers for political reasons. It is like a regular terrorist attack in that it requires highly skilled individuals, millions of dollars to execute, and years of planning. The term cyperextortionist is someone who uses email as an attacking force. They usually sent a very threatening email to the company, stating that they would release some confidential information, exploit a security breach, or launch an attack that would damage the company's network. They will demand the amount paid so that it does not run as extortion from then on. An unethical employee is an employee who illegally accesses the company network for many reasons. One of them might be the money they can get by selling top secret information, or some might be bitter and want revenge. A screenwriter is someone who is like a cracker because they may intend to do harm, but they usually lack technical skills. They are usually dumb teenagers who use pre-written hacking and cracking programs. A corporate spy has extremely high computer and networking skills and is hired to break into a specific computer or computer network to steal or delete data and information. Shady companies hire these types of people in a practice known as corporate espionage. They do this to gain an advantage over competition and illegal practices. Business and home users must do their best to protect or secure their computers from security risks. The next part of this article will provide some advice on how to protect your computer. However, it is important to remember that there is no 100% guaranteed way to protect your computer, so learning more about them is a must these days. When you transmit information over a network, it has a high security risk compared to information transmitted on a business network because administrators usually take some extreme measures to help protect against security risks. There is no executive administrator over the internet, which increases the risk. If you are not sure if your computer is vulnerable to a cyber risk, 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 provide some advice on how to fix these vulnerabilities. The Computer Emergency Response Team Coordination Center is the place to do this. Typical network attacks that threaten computers include viruses, worms, spoofing, Trojan horses, and denial-of-service attacks. Any unprotected computer is vulnerable to a computer virus, which is a potentially harmful computer program that negatively infects the computer and changes the way the computer works without the user's consent. Once a virus is on a computer, it can spread by infecting other files and potentially damaging the operating system itself. It is similar to a bacterial virus that infects humans because it enters the body through small openings and can spread to other parts of the body and cause some damage. The similarity is that the best way to avoid is to prepare. A computer worm is a program that copies itself repeatedly and is very similar to a computer virus. However, the difference is that the virus needs to attach itself to the executable file and become part of it. A computer worm doesn't need to do that, it seems to me that it copies itself and other networks and takes up a lot of bandwidth. Named after a famous Greek myth, Trojan horse is used to describe a program that hides itself secretly and actually looks like a legitimate program but is fake. A specific action usually triggers a Trojan horse, and unlike viruses and worms, it does not replicate itself. Computer viruses, worms, and Trojan horses are classified as malicious logical programs, which are just programs that intentionally harm a computer. Although these are the common three, there are many more variations and it would be almost impossible to list them all. You can tell if your computer is infected with a virus, worm, or Trojan horse when one or more of the following actions occur:
? Screenshots of strange messages or images appear.
? You have less available memory than you expected
? Music or sounds are played randomly.
? Files will get corrupted
? Programs are files that do not work properly
? Unknown files or programs appear randomly
? System properties vary
Computer viruses, worms, and Trojans deliver their payloads or instructions in four common ways. First, when an individual runs an infected program, so if you download a lot of stuff, you should always scan files, especially executable files, before running. Second, when an individual runs an infected program. Third, when an individual boots a computer with an infected disk, it is therefore important not to leave media files on the computer when you shut it down. Fourth, it connects the unprotected computer to the network. Today, a very common way for people to become infected with a computer virus, worm or Trojan horse is by opening an infected file via an email attachment. There are literally thousands of computer malicious logic professionals
