Final answer:
Full disk encryption is the best option to protect the data on the CEO's laptop. Biometric authentication can be used as an additional security measure. A strong password and antivirus software are important but do not address data protection if the laptop is physically compromised.
Step-by-step explanation:
The best option to protect the data on the CEO's laptop from being compromised if lost or stolen would be full disk encryption. Full disk encryption ensures that all data stored on the laptop's hard drive is encrypted, meaning it is scrambled and unreadable without the encryption key. This prevents unauthorized access to the data even if the laptop falls into the wrong hands. Biometric authentication is another security measure that can be used in addition to full disk encryption. It involves using a unique physical characteristic, like a fingerprint or iris scan, to verify the user's identity. This adds an extra layer of protection by ensuring that only authorized individuals can access the laptop. While a strong password is important, it alone may not be sufficient to protect the data if the laptop is lost or stolen. Passwords can be cracked or bypassed, especially if they are not complex or frequently changed. Antivirus software is also crucial for protecting against malware and other threats, but it does not specifically address the issue of data protection if the laptop is physically compromised.
