Detecting a spoofed image in an information handling system

1. A computer implemented method for detecting a spoofed image in an information handling system (IHS), the method comprising:

triggering, by a processor of a diagnostic IHS, a controller to execute a diagnostic image for testing an image under test, the controller being a component of the IHS and comprising a memory having the image under test, the diagnostic image using the image under test as inputs and returning test results for a given input according to mathematical functions, the image under test being a firmware image;

receiving at least one first test result from the controller executing the diagnostic image on the image under test, the test results being values and an order of sequence calls returned by the diagnostic image;

determining whether the first test result is a valid first test result, the valid first test result comprising pre-determined values and based on a pre-determined order of sequence calls, and indicating that the image under test is authentic; and

in response to determining that the first test result is not a valid first test result:

identifying the image under test as a spoofed image that has failed testing; and

triggering the controller to prevent loading of the spoofed image that has failed testing.

2. The method of claim 1 , further comprising:

generating an error message that identifies the image under test as being a spoofed image and storing the error message to an error log.

comparing the first test result to a pre-determined valid first test result, the pre-determined valid first test result being pre-determined values and order of sequence of calls that indicate that the stored image under test is authentic; and

determining whether the first test result matches the pre-determined valid first test result.

4. The method of claim 1 , further comprising:

notifying a system administrator that the image under test is a spoofed image that has failed testing.

in response to identifying the image under test as a spoofed image, triggering the controller to delete the spoofed image that has failed testing.

7. The method of claim 1 , further comprising:

in response to identifying the image under test as a spoofed image:

retrieving a trusted image corresponding to the spoofed image;

transmitting the trusted image to the controller; and

triggering the controller to store the trusted image in place of the spoofed image which is deleted.

in response to determining that the first test result is not a valid first test result:

identify the image under test as a spoofed image that has failed testing; and

trigger the controller to prevent loading of the spoofed image that has failed testing.

9. The information handling system of claim 8 , wherein the firmware further configures the processor to:

generate an error message that identifies the image under test as being a spoofed image and store the error message to an error log.

execute the diagnostic image;

generate the at least one first test result; and

transmit the at least one first test result to the processor.

13. The information handling system of claim 8 , wherein the firmware further configures the processor to:
