What are 'security breaches'?

Security breaches refer to incidents where unauthorized access or actions occur that violate established security policies. This can encompass a range of events, such as hacking attempts, unauthorized access to sensitive information, or any situation where an individual gains access to restricted areas or data without permission. The term highlights the breach of security protocols intended to protect sensitive information and maintain the integrity of a secure environment.

The other options do not accurately define security breaches. Scheduled drills are proactive measures taken to prepare personnel for emergency situations, routine checks focus on compliance and adherence to safety regulations, and reports about daily activities are records of operations rather than incidents of security failure. Therefore, the definition provided accurately captures the essence of what constitutes a security breach in the context of security operations.
