Concept
Cyberattack
Summary
A cyberattack is any offensive maneuver that targets computer information systems, computer networks, infrastructures, personal computer devices, or smartphones. 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 organizations and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyber weapon. Cyberattacks have increased over the last few years. A well-known example of a cyberattack is a distributed denial of service attack (DDoS).
A cyberattack may steal, alter, or destroy a specified target by hacking into a private network or otherwise susceptible system. Cyberattacks can range from installing spyware on a personal computer to attempting to destroy the infrastructure of entire nations. Legal experts are seeking to limit the use of the term to incidents causing physical damage, distinguishing it from the more routine data breaches and broader hacking activities.
Cyberattacks have become increasingly sophisticated and dangerous.
User behavior analytics and Security Information and Event Management (SIEM) can be used to help prevent these attacks.
Since the late 1980s, cyberattacks have evolved several times to use innovations in information technology as vectors for committing cybercrimes. In recent years, the scale and robustness of cyberattacks have increased rapidly, as observed by the World Economic Forum in its 2018 report: "Offensive cyber capabilities are developing more rapidly than our ability to deal with hostile incidents".
In May 2000, the Internet Engineering Task Force defined attack in RFC 2828 as:
an assault on system security that derives from an intelligent threat, i.e.
