Information About the ASA CX Module

The ASA CX module lets you enforce security based on the full context of a situation. This context includes the identity of the user (who), the application or website that the user is trying to access (what), the origin of the access attempt (where), the time of the attempted access (when), and the properties of the device used for the access (how). With the ASA CX module, you can extract the full context of a flow and enforce granular policies such as permitting access to Facebook but denying access to games on Facebook, or permitting finance employees access to a sensitive enterprise database but denying the same access to other employees.
