Abstract
The disclosed embodiments include a method for receiving data packets at a host system. In one embodiment, the method includes the steps of: intercepting a data packet, at a data link layer, that is being sent to an input/output (I/O) port of the host system using a hardware device that is located between a hardware network interface and the input/output port of the host system; reading, using the hardware device, at least one parameter from the data packet; determining, by the hardware device using instructions written in memory of the hardware device, whether the at least one parameter meets an authentication criteria, wherein the host system is unable to write to the memory of the hardware device; and in response to determining that the at least one parameter meets an authentication criteria, forwarding, by the hardware device, the data packet to the input/output port of the host system.
