What constitutes a breach of security?

A breach of security is defined as an event where unauthorized individuals gain access to restricted areas or information that is meant to be safeguarded. This could involve physical spaces such as secure buildings or sensitive data files that contain confidential or proprietary information. The essence of security is to ensure that only those with the proper authorization can enter or view certain information. A breach undermines that security framework and can lead to various risks, including theft, data loss, or compromised safety.

The other options, while they may represent issues within a security operation, do not fit the definition of a security breach. Working overtime without permission relates more to operational protocol rather than a security violation. Miscommunication among security staff can lead to inefficiencies but does not necessarily involve unauthorized access or exposure. Similarly, minor policy violations, while potentially problematic, typically do not equate to a breach of security unless they involve unauthorized access or severe oversight that compromises safety or confidentiality.
