_________ is a fully-contained program that self-replicates and spreads through computers and networks
Massive networks of zombies that can be used by a hacker to spread malware, send spam, and conduct carefully orchestrated network attacks. bridge A device that connects two LANs or two segments of the same LAN; looks at the information in each packet header and forwards data traveling from one LAN to another. In networks, it refers to the amount of data that can be transmitted over a given amount of time. botnet Massive networks of zombies that can be used by a hacker to spread malware, send spam, and conduct carefully orchestrated network attacks. A device that connects two LANs or two segments of the same LAN; looks at the information in each packet header and forwards data traveling from one LAN to another. It is important to note that a virus cannot be spread without a human action, (such as running an infected program) to keep it going. Because a virus is spread by human action people will unknowingly continue the spread of a computer virus by sharing infecting files or sending emails with viruses as attachments in the email. Fast Facts: Attaches to an executable file, requires human action to spread. Massive networks of zombies that can be used by a hacker to spread malware, send spam, and conduct carefully orchestrated network attacks. bridge. A device that connects two LANs or two segments of the same LAN; looks at the information in each packet header and forwards data traveling from one LAN to another. coaxial cable. A cable that consists of a single copper wire that is surrounded by insulation and a wire mesh shield. Data moves through networks in structures known as ___, which are pieces of a message broken down into small units by the sending device and reassembled by the receiving device. Most network installations use a(n) ___ star topology with twisted-pair cables that plug into the RJ45 port located on many devices. Trojans often are spread via an infected email attachment or a download that hides in free games, applications, movies or greeting cards. Your computer will often slow down due to a Trojan. A Computer Worm is a program that self-replicates and spread through networks. They are transmitted through attachment, file-sharing networks and links. They consume large amounts of memory or bandwidth and the network servers will often stop responding because of them. Rootkit is a program that allows hackers to have administrative access to your computer. It can be installed through commercial security products or third-party app extensions. Detecting rootkit-like behavior can be tedious work. A Computer Virus is a program or piece of code that is loaded onto your computer without your knowledge or permission. Most viruses are destructive and designed to infect and gain control over vulnerable systems. A virus can spread across computers and networks by making copies of itself. A type of malware that self-replicates and spreads through computers and networks without the need to attach to a host file. zombie An infected and compromised computer that is under the external control of a hacker, usually without the knowledge of the computer's owner. The use of a computer and/or network to commit a variety of crimes, such as creating viruses or disrupting networks. cyberterrorism A dangerous form of hacking that seeks to create large-scale chaos and damage to a country's infrastructure. A computer virus attaches itself to a program or file enabling it to spread from one computer to another, leaving infections as it travels. Like a human virus, a computer virus can range in severity: some may cause only mildly annoying effects while others can damage your hardware, software or files.
