What is a “security breach”?

A security breach is defined as an incident in which unauthorized access is obtained to protected data or secure areas. This encompasses situations in which individuals or groups exploit weaknesses in security measures, potentially leading to the exposure of sensitive information or the unauthorized use of facilities.

The focus is on the unauthorized nature of access, which is central to recognizing a security breach. It identifies not only the potential risk posed to the information systems involved but also the implications for individuals and organizations regarding data privacy and security. Such breaches can have significant consequences, including financial loss, reputational damage, and legal liabilities.

While other concepts, like protocol violations or failure to secure perimeters, can relate to security lapses, they do not encompass the broader definition of a security breach that involves direct unauthorized access to protected areas or data.
