Data breach is a suspected breach of sensitive data by exposing the data to the risks of accidental loss, or unauthorised or accidental access, processing, erasure or use. Data breaches could result from cyber attacks to computer systems, networks or cloud storage during which cyber criminals gain unauthorised access to sensitive data such as personal data and financial data. Besides outsiders, data breaches could be caused by vicious insiders (e.g. privilege abuse), human errors (e.g. security misconfiguration) and negligence of users (e.g. loss of USB drive).
Typically, cyber criminals will target personal data such as name, identity card number, email address, username, password, credit card number or any data that can be used for criminal or dishonest purposes (e.g. deception). For businesses, valuable data such as financial record, intellectual property, trade secret and customer data can be targeted by cyber criminals for financial gain.
