No matter what your role is within an organization, this data security glossary is intended for anyone from the security leader to the security practitioner.

Data breach

A data breach means that an unauthorized person has successfully infiltrated an organization’s data stores and viewed, taken or shared data. Contributing factors that may lead to a breach include shadow data, misconfigurations, cyber attacks, social engineering, human error, or physical theft of devices containing data. If a data breach involves sensitive, confidential or regulated data, an organization may face adverse business impacts including increased regulatory scrutiny, financial losses, and loss of customer trust. There is also a possibility that the threat actor will use stolen data for fraudulent activities in the future.
