US Patent 8984606 Re-authentication

In one example, a method of managing access to a network includes receiving a network access request including one or more credentials via an edge device. The one or more user credentials are authenticated, and a database record for a user associated with the one or more user credentials is identified. A re-authentication duration value is obtained from the database record for the user, wherein the re-authentication duration value is pre-assigned to the user or pre-assigned to a group associated with the user. A response comprising the re-authentication duration value is then sent to the edge device.
