Context-aware authentication is a technique that allows network administrators to make security decisions based on various factors related to the user’s behavior and the context of their requests. This approach takes into consideration multiple variables, such as the user’s location, the device being used, the time of access, and the type of request being made. By analyzing these patterns, context-aware authentication helps to determine whether the user’s request is legitimate or potentially malicious.

This method stands out because it adapts to changes in the user’s environment and usage patterns, effectively enhancing security by adding layers of verification based on real-time context. For instance, if a user typically accesses the network from a specific location during business hours but suddenly tries to log in from a different location at an unusual time, the system could flag this access attempt for further scrutiny.

In contrast, token-based authentication primarily focuses on verifying user identities through the use of secure tokens, which do not necessarily incorporate behavioral patterns. Privileged access management deals with controlling and monitoring access for users with elevated permissions, while multi-factor authentication requires multiple forms of verification but does not specifically assess user behavior or request patterns in the same contextual way.
