What is a data breach in database management?

A data breach in database management is accurately defined as an incident where unauthorized access to data occurs, compromising confidentiality. This means that an individual or group gains access to sensitive information without permission, which can lead to the exposure of personal, financial, or proprietary data. The consequences of a data breach can be severe, resulting in financial losses, reputational damage, and legal ramifications for the organization involved.

The correct understanding of a data breach focuses on the aspect of unauthorized access, which directly threatens the security of sensitive information. It highlights the importance of protective measures such as encryption, access controls, and monitoring systems to prevent such incidents. Being aware of what constitutes a data breach helps organizations better prepare for and respond to potential security threats.
