Abstract: Provided are an electronic device and a method of controlling same. The method of controlling the electronic device: displays a UI including a security index showing that the electronic device is in a state operating in a secure mode; compares the security index to a reference security index and determines whether the security index has been falsified; and when the security index is a falsified security index, shows that the security index is a security index that has been falsified.
