Which Part of the Triad Took the Hit?

About this interactive

The lesson's security triad: - **Confidentiality:** information reaches only the people meant to see it. Card numbers stolen from a checkout page, or payroll printouts found in a dumpster, are breaches of confidentiality. - **Integrity:** information and systems are not altered without authority. A hacker who redirects your website's buyers to another store has broken its integrity. - **Availability:** systems and data are there when needed. A site that is down cannot sell; a fire, a flood of traffic or a careless change can all take it down. In the lesson's threats-to-an-asset view, stolen or copied data is confidentiality, altered data is integrity, and deleted data is availability.
