A unified access control component (UACC) can maintain information relating to network access information and physical location information associated with respective users who may access a network that can include network resources (e.g., applications, information). The UACC can cross reference the network access information (e.g., user network access events, credentials, and policy) and physical location information (e.g., user physical access events, credentials, and policy) and can generate and enforce a unified network access policy based on network access information and physical location information associated with a particular user. After network access privileges have been granted to a user, the UACC can continue to monitor the user. The UACC can include a dynamic authentication component that can request a user re-authenticate if a change in the physical location and/or network access associated with the user is detected, such that a re-computation of network access privileges is desired.
