Frequently Asked Questions
What is the difference between a data breach and a data leak?
The words overlap and are often used interchangeably. In careful usage, a breach implies protections were broken or bypassed, usually by someone acting deliberately, while a leak suggests information was left exposed through error or misconfiguration and could simply be found. Both result in information reaching people who should not have it.
What is the difference between a data breach and a hack?
A hack describes unauthorised access to a system, which is one way a breach can happen. A data breach is defined by the outcome: information ending up outside its intended boundary. A breach can occur with no hacking at all, for instance when a database is left open to the internet or a file is emailed to the wrong recipient.
Does a data breach always involve passwords?
No. What is exposed depends entirely on what the organisation held, and can be names, addresses, order histories, medical records or internal documents. Where passwords are involved, they may be stored in scrambled form, which affects how readily they can be used.
