Cyberattack

A cyberattack (also called a computer network attack (CNA)) uses malicious computer code to disrupt computer processing or steal data. The malicious code can be directed against computer processing code, instruction logic, or data. The code can generate a stream of malicious network packets that can disrupt data or logic through exploiting a vulnerability in computer software, or a weakness in the computer security practices of an organization. This type of cyberattack can disrupt the reliability of equipment, the integrity of data, and the confidentiality of communications.
