Methods and systems are disclosed for detecting a security threat. The methods and systems comprise detecting that a first device is coupled with the first I/O interface, responsive to the detection that the first device is coupled with the first I/O interface, temporarily disabling data communication between the first and second I/O interfaces, acquiring a file from the detected first device via the first I/O interface, determining whether the acquired file poses a security threat, and responsive to a determination that the acquired file does not pose a security threat, enabling the data communication between the first and second I/O interfaces.
