Which of the following actions would violate the Computer Misuse Act?

Gaining unauthorized access to computer data is a clear violation of the Computer Misuse Act. This law is designed to protect computer systems and data from misuse, ensuring that individuals do not access data without permission from the rightful owner or system administrator. Unauthorized access can include hacking into systems, bypassing security measures, or exploiting vulnerabilities to view, alter, or delete data without authorization.

The act specifically targets activities that compromise the integrity or confidentiality of data and the security of computer systems. Therefore, engaging in any form of unauthorized access is not only unethical but also illegal under this legislation. This is critical as it establishes a legal framework that aims to curb cybercrime and protect individuals and organizations from malicious activities involving their digital assets.

In contrast, accessing approved data for work, updating software legally, and backing up personal data represent responsible and authorized activities that comply with legal standards and corporate policies. These actions are necessary for effective and secure data management within organizations.
