Systems and methods for controlling access to a peripheral device
The disclosed computer-implemented method for controlling access to a peripheral device may include receiving an input/output request related to a process attempting to access the peripheral device. The method can also include determining an access state for the process indicative of whether the process will be allowed to gain access to the peripheral device. The access state can be based on a context property of the process. The method can further include responding to the input/output request with initiation of a virtual peripheral output from a virtual peripheral device if the access state is indicative of the process not being allowed access to the peripheral device. Various other methods, systems, and computer-readable media are also disclosed.
