Computer security, cybersecurity, digital security or information technology security is the protection of computer systems and networks from attacks 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.
Cybercrime encompasses a wide range of criminal activities that are carried out using digital devices and/or networks. These crimes involve the use of technology to commit fraud, identity theft, data breaches, computer viruses, scams, and expanded upon in other malicious acts. Cybercriminals exploit vulnerabilities in computer systems and networks to gain unauthorized access, steal sensitive information, disrupt services, and cause financial or reputational harm to individuals, organizations, and governments.
Intrusion Countermeasures Electronics (ICE) is a term used in cyberpunk literature to refer to security programs which protect computerized data from being accessed by hackers.
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 evaluation of a system weaknesses to assist in formulating defenses against potential hackers.
Internet police is a generic term for police and government agencies, departments and other organizations in charge of policing the Internet in a number of countries. The major purposes of Internet police, depending on the state, are fighting cybercrime, as well as censorship and propaganda.
EC-Council is a cybersecurity certification, education, training, and services company based in Albuquerque, New Mexico.
Computer security software or cybersecurity software is any computer program designed to influence information security. This is often taken in the context of defending computer systems or data, yet can incorporate programs designed specifically for subverting computer systems due to their significant overlap, and the adage that the best defense is a good offense.
A computer security conference is a convention for individuals involved in computer security. They generally serve as meeting places for system and network administrators, hackers, and computer security experts.
There is no commonly agreed single definition of “cybercrime”. It refers to illegal internet-mediated activities that often take place in global electronic networks. Cybercrime is "international" or "transnational" – there are ‘no cyber-borders between countries'. International cybercrimes often challenge the effectiveness of domestic and international law, and law enforcement. Because existing laws in many countries are not tailored to deal with cybercrime, criminals increasingly conduct crimes on the Internet in order to take advantages of the less severe punishments or difficulties of being traced.
The following outline is provided as an overview of and topical guide to computer security:
The cyber-arms industry are the markets and associated events surrounding the sale of software exploits, zero-days, cyberweaponry, surveillance technologies, and related tools for perpetrating cyberattacks. The term may extend to both grey and black markets online and offline.
Offensive Security is an American international company working in information security, penetration testing and digital forensics. Operating from around 2007, the company created open source projects, advanced security courses, the ExploitDB vulnerability database, and the Kali Linux distribution. The company was started by Mati Aharoni, and employs security professionals with experience in security penetration testing and system security evaluation. The company has provided security counseling and training to many technology companies.
Stephen Cobb is an expert on security, privacy, and the risks related to digital technology.
David "Dave" Venable is a former intelligence officer with the United States National Security Agency, and current cyber security professional and businessman. He is an author and speaker on the topics of cyber security, cyberwarfare, and international security; has developed security-related internet protocols; is a US patent holder; and has been named as one of the most influential people in security.
Ghana has one of the highest rates of cybercrime in the world, ranking 7th in a 2008 Internet Crime Survey. The most popular form of cybercrime in Ghana is cyberfraud and is typically achieved via credit card fraud. However, recent decreases in universal credit card usage has seen the expansion of other cybercrimes such as blackmail and hacking. This growth in crime has warranted a government response, with policies specifically addressing the cyberspace being developed. This has necessitated various studies including a cyber security maturity study which was inaugurated by the Ministry of Communications and conducted by the Global Cyber Security Capacity Center (GCSCC) of the University of Oxford in collaboration with the World Bank.
This is a list of cybersecurity information technology. Cybersecurity is security as it is applied to information technology. This includes all technology that stores, manipulates, or moves data, such as computers, data networks, and all devices connected to or included in networks, such as routers and switches. All information technology devices and facilities need to be secured against intrusion, unauthorized use, and vandalism. Additionally, the users of information technology should be protected from theft of assets, extortion, identity theft, loss of privacy and confidentiality of personal information, malicious mischief, damage to equipment, business process compromise, and the general activity of cybercriminals. The public should be protected against acts of cyberterrorism, such as the compromise or loss of the electric power grid.
Internet security awareness or Cyber security awareness refers to how much end-users know about the cyber security threats their networks face, the risks they introduce and mitigating security best practices to guide their behavior. End users are considered the weakest link and the primary vulnerability within a network. Since end-users are a major vulnerability, technical means to improve security are not enough. Organizations could also seek to reduce the risk of the human element. This could be accomplished by providing security best practice guidance for end users' awareness of cyber security. Employees could be taught about common threats and how to avoid or mitigate them.
Andrea M. Matwyshyn is an American law professor and engineering professor at The Pennsylvania State University. She is known as a scholar of technology policy, particularly as an expert at the intersection of law and computer security and for her work with government. She is credited with originating the legal and policy concept of the Internet of Bodies.
Capture the Flag (CTF) in computer security is an exercise in which participants attempt to find text strings, called "flags", which are secretly hidden in purposefully-vulnerable programs or websites. They can be used for both competitive or educational purposes. In two main variations of CTFs, participants either steal flags from other participants or from organizers. A mixed competition combines these two styles. Competitions can include hiding flags in hardware devices, they can be both online or in-person, and can be advanced or entry-level. The game is inspired by the traditional outdoor sport of the same name.
