Zusammenfassung:A system 100, methods, and an electronic device are disclosed in relation to notifying when security sensitive functionality of an electronic device has been previously enabled, wherein the electronic device comprises a data storage having a current content. Upon detecting an event indicating enabling of security sensitive functionality of the electronic device, a value previously unknown to the electronic device is obtained and the current content of the data storage to a new current content of the data storage is updated according to an updating function based on the current content of the data storage and the value, wherein, without privileged access, the current content of the data storage can only be updated using the updating function. The value is further obtained in a management module and an expected new current content of the data storage is determined in the management module according to the updating function based on a known original content of the data storage and the value. Upon determining that the new current content of the data storage differs from the expected new current content of the data storage, a validation module generates a security notification.
