Data breach
When sensitive or protected information is accessed, exposed or taken without permission
What's it for?
Identifies when sensitive information has been exposed so the organisation can limit harm and respond.
For example…
Customer email addresses are accidentally left publicly downloadable.
An employee accidentally emails a customer spreadsheet to the wrong external address, creating a potential data breach that must be assessed.
Think of it like…
Confidential files left on a train platform — once public, you cannot un-see them, only limit further spread
