Test yourself: pick an answer
Reveal answer & explanation
Correct answer: C) If a laptop is lost or stolen, the data cannot be read by an unauthorised person without the decryption key
Explanation
Encryption converts data into an unreadable form that can only be decoded with the correct key, protecting confidentiality if the device falls into the wrong hands. It does not prevent physical theft, does not back up data and is not a substitute for anti-virus software.
