A security breach is defined as an incident in which there is unauthorized access to or disclosure of sensitive information. This could involve various scenarios, such as hackers accessing confidential data, employees accessing information they are not authorized to view, or any situation where data is compromised. The significance of identifying a breach lies in understanding the potential threats to personal, financial, or proprietary information, which can lead to further legal, financial, and reputational damages for the organization involved.

Other definitions do not accurately reflect what a security breach entails. Enhancing security protocols is a preventative measure that typically follows a breach rather than describing the breach itself. Overstaffing does not pertain to the concept of unauthorized access or information disclosure, and a failure in communication among security teams, while it can lead to vulnerabilities, does not constitute a breach on its own. Therefore, the definition of a security breach is specifically focused on the unauthorized access and compromise of sensitive data.
