In an input/output virtualization-enabled computing environment, a device, method, and system for securely handling virtual function driver communications with a physical function driver of a computing device includes maintaining communication profiles for virtual function drivers and applying the communication profiles to communications from the virtual function drivers to the physical function driver, to determine whether the communications present a security and/or performance condition. The device, method and system may disable a virtual function driver if a security and/or performance condition is detected.
