Breach Definition

A data breach is a security incident in which confidential or sensitive information is accessed, stolen, or otherwise exposed without the authorization of the owner. Data breaches can occur through a variety of means, including hacking, malware, phishing attacks, and social engineering.

When a data breach occurs, the confidential information that is exposed can be used for identity theft, fraud, and a variety of other malicious activities. The potential damage that can be caused by a data breach makes it one of the most serious types of security incidents.

Data breaches can have a significant impact on individuals, businesses, and governments. In addition to the direct damage that can be caused by the exposure of confidential information, data breaches can also lead to indirect damage such as reputation loss and legal liabilities.
