What is a Data Breach?

A data breach occurs when sensitive or confidential information is accessed or disclosed without authorization. This can happen when a hacker gains access to a company’s database, an employee inadvertently shares login credentials, or a third-party vendor experiences a security breach.

Once a data breach occurs, the compromised information can be used for fraudulent purposes, such as identity theft, financial scams, or even blackmail. It’s important to understand that no organization or individual is immune to data breaches, and the consequences can be severe.

The types of information that can be compromised in a data breach include:

Type of Information Description
Personal Identifiable Information (PII) Information that can identify an individual, such as name, address, social security number, or date of birth.
Financial Information Bank account details, credit card numbers, or other financial information that can be used for fraudulent purposes.
Protected Health Information (PHI) Medical records or other health-related information that is protected by law.
Intellectual Property Trade secrets, patents, or other confidential information that can be used for competitive advantage.

It’s important to note that a data breach is not the same as a data leak. A data leak is typically a less intentional event in which information is inadvertently exposed, such as when an email is sent to the wrong person.

Common Causes of Data Breaches

A data breach can happen to any organization, large or small, and for a variety of reasons. Common causes of data breaches include:
