A. B. C. D.D.
Out of the given options, the BEST way to keep the data on a laptop safe if the laptop is lost or stolen is to use full disk encryption (FDE).
Full disk encryption (FDE) is a security feature that encrypts the entire hard drive of a computer, making the data on the disk inaccessible to anyone without the encryption key. This means that even if the laptop falls into the wrong hands, the data on the hard drive remains secure.
A host-based firewall (option A) is a software application that monitors and controls incoming and outgoing network traffic based on an organization's previously established security policies. While it can help protect the laptop from unauthorized network access, it does not provide any protection if the laptop is lost or stolen.
A strong administrator password (option B) is important to prevent unauthorized access to the laptop, but it does not protect the data on the hard drive. If the laptop is lost or stolen, anyone can simply remove the hard drive and access the data directly.
Anti-malware software (option C) is essential for protecting the laptop from malware and viruses that can compromise the system's security. However, it does not encrypt the data on the hard drive, and it cannot prevent unauthorized access to the data if the laptop is lost or stolen.
In summary, full disk encryption (option D) is the best way to keep the data on a laptop safe if it is lost or stolen. It protects the data on the hard drive by encrypting it, making it inaccessible to anyone without the encryption key.
