Computer security, cybersecurity or information technology security is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.
Industrial espionage, economic espionage, corporate spying or corporate espionage is a form of espionage conducted for commercial purposes instead of purely national security.
In programming and hacking cultures, a script kiddie, skiddie, or skid is an unskilled individual who uses scripts or programs, such as a web shell, developed by others to attack computer systems and networks and deface websites. It is generally assumed that most script kiddies are juveniles who lack the ability to write sophisticated programs or exploits on their own and that their objective is to try to impress their friends or gain credit in computer-enthusiast communities. However, the term does not relate to the actual age of the participant. The term is considered to be derogatory.
In Internet activism, hacktivism, or hactivism, is the use of computer-based techniques such as hacking as a form of civil disobedience to promote a political agenda or social change. With roots in hacker culture and hacker ethics, its ends are often related to free speech, human rights, or freedom of information movements.
Cybercrime, or computer-oriented crime, is a crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target. Cybercrime may threaten a person, company or a nation's security and financial health.
Cyberterrorism is the use of the Internet to conduct violent acts that result in, or threaten, loss of life or significant bodily harm, in order to achieve political or ideological gains through threat or intimidation. It is also sometimes considered an act of Internet terrorism where terrorist activities, including 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, and other malicious software and hardware methods and programming scripts. 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 might be difficult to distinguish which instances of online activities are cyberterrorism or cybercrime.
Flooding or scrolling on an IRC network is a method of disconnecting users from an IRC server, exhausting bandwidth which causes network latency ('lag'), or just disrupting users. Floods can either be done by scripts or by external programs.
Steven M. Bellovin is a researcher on computer networking and security. He has been a professor in the Computer Science department at Columbia University since 2005. Previously, Bellovin was a Fellow at AT&T Labs Research in Florham Park, New Jersey.
A security hacker is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering, challenge, recreation, or to evaluate system weaknesses to assist in formulating defenses against potential hackers. The subculture that has evolved around hackers is often referred to as the "computer underground."
Cyberwarfare is the use of digital attacks to attack a nation, causing comparable harm to actual warfare and/or disrupting the vital computer systems. There is significant debate among experts regarding the definition of cyberwarfare, and even if such a thing exists. One view is that the term "cyberwarfare" is a misnomer, since no offensive cyber actions to date could be described as "war". An alternative view is that "cyberwarfare" is a suitable label for cyber attacks which cause physical damage to people and objects in the real world.
Johnny Long, otherwise known as "j0hnny" or "j0hnnyhax", is a computer security expert, author, and public speaker in the United States.
Operation Aurora was a series of cyber attacks conducted by advanced persistent threats such as the Elderwood Group based in Beijing, China, with ties to the People's Liberation Army. First publicly disclosed by Google on January 12, 2010, in a blog post, the attacks began in mid-2009 and continued through December 2009.
An advanced persistent threat (APT) is a stealthy threat actor, typically a nation state or state-sponsored group, which gains unauthorized access to a computer network and remains undetected for an extended period. In recent times, the term may also refer to non-state sponsored groups conducting large-scale targeted intrusions for specific goals.
Low Orbit Ion Cannon (LOIC) is an open-source network stress testing and denial-of-service attack application, written in C#. LOIC was initially developed by Praetox Technologies, but was later released into the public domain, and now is hosted on several open source platforms.
Cyberwarefare is the use of computer technology to disrupt the activities of a state or organization, especially the deliberate attacking of information systems for strategic or military purposes.. As a major developed economy, the United States is highly dependent on the Internet and therefore greatly exposed to cyber attacks. At the same time, the United States has substantial capabilities in both defense and power projection thanks to comparatively advanced technology and a large military budget. Cyber warfare presents a growing threat to physical systems and infrastructures that are linked to the internet. Malicious hacking from domestic or foreign enemies remains a constant threat to the United States. In response to these growing threats, the United States has developed significant cyber capabilities.
China is both the world's second-largest economy and a nuclear weapons state with the world's second-largest defense budget. Chinese Information Operations and Information Warfare includes the concept of “network warfare”, which is roughly analogous to the United States concept of cyber-warfare. Foreign Policy magazine provided an estimated range for China's "hacker army" personnel, anywhere from 50,000 to 100,000 individuals.
Elie Bursztein leads the anti-abuse research team at Google. He is best known for his research on anti-fraud and abuse, his novel attacks against web service and video games and his work on applied cryptography. Prior to Google Bursztein was a post-doctoral fellow in computer science at Stanford University, where he focused on CAPTCHAs security and usability.
In computers and computer networks an attack is any attempt to expose, alter, disable, destroy, steal or gain information through unauthorized access to or make unauthorized use of an asset. A cyberattack is any type of offensive maneuver that targets computer information systems, infrastructures, computer networks, 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 context, cyberattacks can be part of cyberwarfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, society or organizations, and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyberweapon.
