Context-aware authentication

An access control scheme that verifies an object's identity based on various environmental factors, like time, location, and behavior.

The Explain card

Plain English
Context-aware authentication verifies identity using environmental signals such as time, location and behaviour, not just credentials. The same password from an unusual place gets a different answer.
Example
A developer normally uses the AI platform from the office during work hours. A login with valid credentials from a new country at 2 a.m., followed by bulk downloads of model artefacts, triggers a step-up challenge and alerts the SOC.
Why it matters
Stolen API keys and session tokens are valid credentials. Context is often the only thing that separates the real user from the attacker holding their key.
Hook
Right password, wrong place, wrong time: still not you.
