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, society or organisations and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyber weapon.
A cyberattack may s†éál, alter, or destroy a specified target by häçking into a 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 häçking 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.
