- [Instructor] An endpoint, such as a laptop, desktop, or tablet, must be protected from data loss as they are also susceptible to data theft. Take steps to protect against data theft. Using strong access control is an important first step, but the next step is to encrypt the data with a strong encryption algorithm. That way, if the device is lost or stolen, or if someone is able to access the data, the only way they can get to the data is if they have the key. To protect the data, the network administrator can choose from either hardware or software encryption. Hardware encryption provides always on encryption. Authentication takes place on the hardware as the device as a dedicated processor that generates an encryption key, which the user's password will unlock.
