Data Breach | Meaning and Definition

What is Data breach?

A data breach meaning is when malevolent insiders or external attackers get unauthorized access to confidential data or sensitive information, such as medical records, financial data, or personally-identifying information. It is one of the most prevalent and costly forms of cybersecurity disasters. They affect organizations of all sizes, industries, and locations, and they happen on a frighteningly frequent basis.

Unintentionally or intentionally, a data attack can happen. When a legitimate data custodian, such as an employee loses or misuses business tools, an unintentional breach occurs. A worker who visits unprotected websites installs a compromised software package on a work laptop, connects to an unsecured Wi-Fi network, then misplaces a laptop or smartphone in a public place, which can lead to a breach.

Breach of data should be prevented at all costs. Many breaches may be avoided with training and awareness, such as those caused by unintended or irresponsible data disclosure or social engineering assaults like Hacking. Training employees on security protocols, assisting them in avoiding social engineering assaults, and properly identifying sensitive data are all examples of preventative measures.

Unauthorized access can be denied, and various forms of assaults on information systems can be prevented using security measures.
