Preventing Access to Misplugged Devices by a Service Processor

摘要

An approach is provided for preventing access to mis=plugged devices by a service processor (SP). The SP retrieves an expected device identifier of a device associated with a hot-plug event. The hot-plug event was received in response to the device being connected to a selected port of a service processor, and the port is one many ports included in the SP. The SP sends a request for a device identifier via the port and actual device identifier is received from the device. The device is validated by comparing the expected device identifier with the actual device identifier. If the identifiers match, a link between the SP and the device is maintained. On the other hand, if the identifiers do not match, the link between the SP and the device is terminated or otherwise inhibited.

1. A method executed by an information handling system comprising one or more processors and a memory, the method comprising:
retrieving an expected device identifier of a device associated with a hot-plug event that was received in response to the device being connected to a selected port of a service processor, wherein the selected port is one of a plurality of ports included at the service processor; sending a request for a device identifier via the selected port; receiving, at the selected port, an actual device identifier; validating the device by comparing the expected device identifier with the actual device identifier; maintaining a link between the service processor and the device in response to the expected device identifier matching the actual device identifier; and inhibiting the link between the service processor and the device in response to the expected device identifier failing to match the actual device identifier.
