Cyber-attacks can take aim at the enterprise, government, military, and other infrastructural assets of a nation, companies or its citizens, where these assets can include physical infrastructure (e.g., power grids, nuclear reactors) as well as computational infrastructure (e.g., computers, networks). Cyber-attacks can be classified by their participating actors (states vs. non-states) and their attack mechanisms (e.g., direct attack, malware, exploits). Cyber-attacks can also be employed on end user devices such as mobile phones and tablets. Cybersecurity Forum, 2021.
