Cyberwarfare
Cyberwarfare is the use of cyber attacks against an enemy state, causing comparable harm to actual warfare and/or disrupting vital computer systems. Some intended outcomes could be espionage, sabotage, propaganda, manipulation or economic warfare. There is significant debate among experts regarding the definition of cyberwarfare, and even if such a thing exists. One view is that the term is a misnomer, since no cyber attacks to date could be described as war. An alternative view is that it is a suitable label for cyber attacks which cause physical damage to people and objects in the real world. Many countries including the United States, United Kingdom, Russia, China, Israel, Iran, and North Korea have active cyber capabilities for offensive and defensive operations. As states explore the use of cyber operations and combine capabilities, the likelihood of physical confrontation and violence playing out as a result of, or part of, a cyber operation is increased. However, meet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyberbullying
Cyberbullying or cyberharassment is a form of bullying or harassment using electronic means. Cyberbullying and cyberharassment are also known as online bullying. It has become increasingly common, especially among teenagers, as the digital sphere has expanded and technology has advanced. Cyberbullying is when someone, typically a teenager, bullies or harasses others on the internet and other digital spaces, particularly on social media sites. Harmful bullying behavior can include posting rumors, threats, sexual remarks, a victims' personal information, or pejorative labels (i.e. hate speech). Bullying or harassment can be identified by repeated behavior and an intent to harm. Victims of cyberbullying may experience lower self-esteem, increased suicidal ideation, and various negative emotional responses, including being anxious, frustrated, angry, or depressed. Cyberbullying is in many cases an extension of already existing traditional bullying. Students who are bullied v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribu ...

Cybernetics
Cybernetics is a wide-ranging field concerned with circular causality, such as feedback, in regulatory and purposive systems. Cybernetics is named after an example of circular causal feedback, that of steering a ship, where the helmsperson maintains a steady course in a changing environment by adjusting their steering in continual response to the effect it is observed as having. Cybernetics is concerned with circular causal processes such as steering however they are embodied,Ashby, W. R. (1956). An introduction to cybernetics. London: Chapman & Hall, p. 1. including in ecological, technological, biological, cognitive, and social systems, and in the context of practical activities such as designing, learning, managing, conversation, and the practice of cybernetics itself. Cybernetics' transdisciplinary and "antidisciplinary" character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.

Cyberterrorism
Cyberterrorism is the use of the Internet to conduct violent acts that result in, or threaten, the loss of life or significant bodily harm, in order to achieve political or ideological gains through threat or intimidation. Acts of deliberate, large-scale disruption of computer networks, especially of personal computers attached to the Internet by means of tools such as computer viruses, computer worms, phishing, malicious software, hardware methods, programming scripts can all be forms of internet terrorism. Cyberterrorism is a controversial term. Some authors opt for a very narrow definition, relating to deployment by known terrorist organizations of disruption attacks against information systems for the primary purpose of creating alarm, panic, or physical disruption. Other authors prefer a broader definition, which includes cybercrime. Participating in a cyberattack affects the terror threat perception, even if it isn't done with a violent approach. By some definitions, it mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CDC Cyber
The CDC Cyber range of mainframe-class supercomputers were the primary products of Control Data Corporation (CDC) during the 1970s and 1980s. In their day, they were the computer architecture of choice for scientific and mathematically intensive computing. They were used for modeling fluid flow, material science stress analysis, electrochemical machining analysis, probabilistic analysis, energy and academic computing, radiation shielding modeling, and other applications. The lineup also included the Cyber 18 and Cyber 1000 minicomputers. Like their predecessor, the CDC 6600, they were unusual in using the ones' complement binary representation. Models The Cyber line included five different series of computers: * The 70 and 170 series based on the architecture of the CDC 6600 and CDC 7600 supercomputers, respectively * The 200 series based on the CDC STAR-100 - released in the 1970s. * The 180 series developed by a team in Canada - released in the 1980s (after the 200 serie ...

Cyberpunk
Cyberpunk is a subgenre of science fiction in a dystopian Futurism, futuristic setting that tends to focus on a "combination of low-life, lowlife and high tech", featuring futuristic technological and scientific achievements, such as artificial intelligence and cybernetics, juxtaposed with societal collapse, dystopia or decay. Much of cyberpunk is rooted in the New Wave science fiction movement of the 1960s and 1970s, when writers like Philip K. Dick, Michael Moorcock, Roger Zelazny, John Brunner (novelist), John Brunner, J. G. Ballard, Philip José Farmer and Harlan Ellison examined the impact of drug culture, technology, and the sexual revolution while avoiding the utopian tendencies of earlier science fiction. Comic book, Comics exploring cyberpunk themes began appearing as early as Judge Dredd, first published in 1977. Released in 1984, William Gibson's influential debut novel ''Neuromancer'' helped solidify cyberpunk as a genre, drawing influence from punk subculture and ...

Cyber Crime
A cybercrime is a crime that involves a computer or a computer network.Moore, R. (2005) "Cyber crime: Investigating High-Technology Computer Crime," Cleveland, Mississippi: Anderson Publishing. The computer may have been used in committing the crime, or it may be the target. Cybercrime may harm someone's security or finances. There are many privacy concerns surrounding cybercrime when confidential information is intercepted or disclosed, lawfully or otherwise. Internationally, both governmental and non-state actors engage in cybercrimes, including espionage, financial theft, and other cross-border crimes. Cybercrimes crossing international borders and involving the actions of at least one nation-state are sometimes referred to as cyberwarfare. Warren Buffett describes cybercrime as the "number one problem with mankind" and said that cybercrime "poses real risks to humanity." A 2014 report sponsored by McAfee estimated that cybercrime resulted in $445 billion in annual damage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Cyber
Doctor Cyber is a fictional character appearing in DC Comics publications and related media, commonly as a recurring adversary of the superhero Wonder Woman. She first appeared late in the Silver Age of Comics in 1968's ''Wonder Woman'' (volume 1) #179, written by Dennis O'Neil and illustrated by Mike Sekowsky and Dick Giordano. In her Silver Age appearances, Dr. Cyber was the brilliant head of a vast global criminal network. Beautiful, vain and possibly British or of Asian descent (or both), she initially blended aspects of the femme fatale and dragon lady character tropes. Subsequent Bronze Age appearances incorporated science fiction elements: after her face was disfigured in an accident, Dr. Cyber donned an eerie muzzle-mask and a technologically advanced exoskeleton. These cybernetic enhancements increased her physical strength, and gave her the ability to absorb energy, as well as to redirect it by firing blasts from her hands. Despite the resulting upgrades to her p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyber-attack
A cyberattack is any offensive maneuver that targets computer information systems, computer networks, infrastructures, or personal computer devices. An attacker is a person or process that attempts to access data, functions, or other restricted areas of the system without authorization, potentially with malicious intent. Depending on the context, cyberattacks can be part of cyber warfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, societies or organisations and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyber weapon.

Cyberspace
Cyberspace is a concept describing a widespread interconnected digital technology. "The expression dates back from the first decade of the diffusion of the internet. It refers to the online world as a world 'apart', as distinct from everyday reality. In cyberspace people can hide behind fake identities, as in the famous The New Yorker cartoon." (Delfanti, Arvidsson, 150) The term entered popular culture from science fiction and the arts but is now used by technology strategists, security professionals, government, military and industry leaders and entrepreneurs to describe the domain of the global technology environment, commonly defined as standing for the global network of interdependent information technology infrastructures, telecommunications networks and computer processing systems. Others consider cyberspace to be just a notional environment in which communication over computer networks occurs. The word became popular in the 1990s when the use of the Internet, networkin ...
