Abstract
In some examples, an electronic device includes a component comprising information, a secure storage, and a controller to generate a digital signature based on the information of the component, and detect a modification of the component based on the digital signature. The controller can also detect a receipt of an invalid credential, and log, to the secure storage, an indication of the modification of the component and an indication of the receipt of the invalid credential.
