Research that cracks the ability of an attacker to quickly control numerous Internet hosts poses a serious threat to the overall security of the Internet (Staniford, Paxson & Weaver, 2002). When attacked, these hosts can not only handle large-scale distributed denial of service (DDoS) attacks, but also to steal or destroy large amounts of confidential information by confusing or destroying the network in more complicated ways Also used. An attacker performs this task by sending an intrusion agent, often called a "worm".
This is called cyber terrorism. Using the Internet makes your computer vulnerable to attack by these hackers and predators. Hackers create things such as computer virus threats, spyware, phishing, worms, rootkits, zombies, mouse catching etc. Most of these computer security threats are computer viruses. A virus is a program that changes the behavior of a computer. Viruses can duplicate themselves and run them, potentially damaging the computer. The threat of spyware can monitor your online activity without your permission and you can install software to obtain personal information.
Anyone using a computer connected to the Internet is vulnerable to the threat posed by computer hackers and online predators. These Online Service-to-Seniors endanger computers by providing dangerous malware to computers using phishing scams, spam or instant messaging, and fake websites. If not protected by a firewall, computer hackers can also try to access your computer and personal information directly. They can monitor your conversation and read the back end of your personal website. Usually, pretending to be a fake identity, predators may induce you to disclose confidential personal or financial information, or may have even worse results.
Organization's computer security could be compromised by serious hackers, computer beginners of interest, fraudulent suppliers and competitors, dissatisfaction with current or former employees, organized crime, and even spy agents. The Internet provides rich information on known security vulnerabilities of hardware and software to banks and hackers. With almost all search engines, common Internet users can quickly find information explaining how to access various systems by exploiting known security vulnerabilities and software errors. After exploiting the vulnerability assessment tool to investigate the network system, hackers may exploit the identified vulnerability to gain unauthorized access to the system and violate security. Internal exploitation of information systems is still a security threat that continues to exist.
