What is the definition of a data breach?

The definition of a data breach encompasses both intentional and unintentional events resulting in the exposure, disclosure, or loss of secure information. This captures the broader nature of how breaches can occur—through malicious acts, such as hacking, or through inadvertent actions, such as sending an email to the wrong recipient.

While unauthorized access to secure information is specific to the act of gaining such access without consent, it does not fully encompass scenarios where data might be exposed through unintentional means. Moreover, the term "loss of personal data due to natural disasters" is too narrow and doesn't incorporate the various ways data breaches can occur. Lastly, the regulation of data handling within a company does not define a data breach but rather describes compliance and governance procedures regarding data management. Understanding the full spectrum of potential incidents that lead to a breach is crucial for effective data privacy and protection strategies.
