A 'data breach' is defined as an unauthorized access to confidential data. This typically involves individuals or entities gaining access to sensitive information, such as personal identification information, financial records, or proprietary business data, without permission. Such incidents can occur through various methods, including hacking, phishing attacks, or exploiting vulnerabilities in cybersecurity defenses.

Understanding this definition is crucial because it highlights the importance of data security measures and the potential risks associated with inadequate protection of information. Organizations strive to prevent data breaches due to the severe consequences, including financial loss, legal ramifications, and damage to reputation.

The other choices reflect different concepts. A security update pertains to improvements made to enhance system defenses, a successful marketing campaign relates to promotional strategies, and a planned maintenance procedure involves routine checks and updates to ensure systems operate smoothly. None of these involve unauthorized access to sensitive data, which is the core aspect of a data breach.
