What is a data breach?

A data breach is defined as an incident where there is unauthorized access to personal data. This means that an individual or entity gains access to data without the permission of the data owner, which can lead to the exposure of sensitive information. This can occur through various means, such as hacking, malware, or even improper disposal of information that can be accessed by others. The significance of identifying a data breach accurately lies in the need for organizations to respond effectively to mitigate any potential harm caused by the unauthorized access, including legal repercussions and damage to reputation.

Understanding the nature of a data breach is crucial for implementing appropriate security measures and ensuring compliance with data protection regulations. Recognizing unauthorized access as a core characteristic of a breach helps organizations focus on strengthening their defenses against such incidents.
