会社の携帯電話が技術者の車から盗まれました。携帯電話にはパスコードがありますが、クライアントとベンダーに関する機密情報が含まれています。次のうち、有効にする必要があるものはどれですか?
正解:C
* Encryption is the process of transforming data into an unreadable format using a secret key or algorithm.
It can protect sensitive information from unauthorized access or theft, even if the device is lost or stolen.
* Factory reset is the process of restoring a device to its original settings and deleting all user data and applications. It can be used to erase personal information from a device before selling or disposing of it, but it does not prevent data recovery by forensic tools. Therefore, option A is incorrect.
* Autolock is the feature that automatically locks a device after a period of inactivity or when the power button is pressed. It can prevent unauthorized access to a device by requiring a passcode, pattern, fingerprint, or face recognition to unlock it. However, it does not protect the data stored on the device from being extracted by other means. Therefore, option B is incorrect.
* Two-factor authentication is the method of verifying a user's identity by requiring two pieces of evidence, such as a password and a code sent to a phone or email. It can enhance the security of online accounts and services, but it does not apply to the data stored on a device. Therefore, option D is incorrect.
