Abstract: The invention described herein is that of systems and methods for agentless identity-based authentication of network-enabled devices for control of network traffic to and from each device based on identity. The invention leverages X.509 certificates associated with network devices and comprises at least one querying device in communication with at least target device and optionally at least one intermediate device, such as but not limited to a switching device that can interface with the target device and enable the querying device to query the target device to obtain an X.509 certificate and any extensions, then dictate switching actions, which may be carried out by the querying device according to instructions provided by a switching module residing on the querying device or located external to the querying device. The systems and methods described herein are suitable for validation of the identities of fixed application devices to prevent unauthorized network access.
