Think of a security breach as theft. If someone breaks a window and climbs into your house, that is a security breach. If the intruder stole your documents and personal information and exited the window again, that's a data breach, but we'll talk about that later.
Security breaches happen frequently, not necessarily in your home, but in organizations large and small. A security breach can damage the organization's reputation and finances. If your data gets deleted during the process, this may affect you as well.
Widespread security and data breaches can occur. Think about the Equifax data breach in 2017 when hackers accessed the personal information of more than 145 million Americans. Or the Yahoo data breaches, first reported in 2016, which exposed 3 billion user accounts.
What is a security breach by definition? A security breach occurs when an intruder obtains unauthorized access to an organization's protected systems and data. Cyber criminals or malicious apps bypass security mechanisms to access restricted areas. A security breach is an early-stage breach that can lead to system corruption and data loss.
