ISE posture requirement to check if endpoint's USP port is disabled

Question

Hi,
I wonder if it is possible to set the disabled USP Port in the endpoints as a requirement in ISE Posture ?
Appreciate your input.

If your question pertains to the capability of the ISE disabling the USB port on a PC, then the answer is no.
Using the NAC agent, however, you can check various programs and may be able to check the condition of USB.
You would have to create a New Posture Condition and Remediations.
The condition that I will use in this example is a Registry Key.
If the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor\Start" has a value of 3, the USB is enabled.  A value of 4 is disabled.
So set a Posture Condition:
Click Policy > Policy Elements > Conditions
Choose Posture from the left menu:
Then choose Registry Condition from the left menu.
Click +Add to add a new Posture Condition:
Then you have to create Remediation Actions.  Click the Results button at the top of the left Menu:
Choose Remediation Actions and choose the Remediation you want to use.  I chose Link Remediation.
+Add to add a new Link Remediation:
Then choose Requirements from the left menu and create a new Remediation Result:
Of course, you can choose different remediations as necessary for your environment.
