Abstract: Techniques are disclosed relating to securing an accessory interface on a computing device. In various embodiments, a computing device detects a connection of an accessory device to an accessory interface port and, in response to the detected connection, evaluates a policy defining one or more criteria for restricting unauthorized access to the accessory interface port. Based on the evaluating, the computing device determines whether to disable the accessory interface port to prevent communication with the connected accessory device. In some embodiments, the computing device includes an interconnect coupled between the processor and the accessory interface port, and the interconnect includes a hub circuit configured to facilitate communication between a plurality of devices via the interconnect. In some embodiments, the computing device, in response to determining to disable the accessory interface port, instructs the hub circuit to prevent traffic from being conveyed from the accessory interface port.

Abstract: The subject technology provides systems and methods for logging data access by applications. A first process executing on an electronic device may receive an access request from a second process executing on the electronic device. The access request may include a request to access data corresponding to a protected data category. Subsequent to receiving the access request, the first process may determine whether the second process is authorized to access the data. In response to determining that the second process is authorized to access the data, the first process may grant the second process access to the data, and then generate and store log data corresponding to the access of the data by the second process.
