The best method to safeguard data on an organization’s laptop computers is full disk encryption. Full disk encryption is a technique that encrypts all the data stored on a harddrive, including the operating system, applications, files, and folders. This means that if the laptop is lost, stolen, or accessed by an unauthorized person, they will not be able to read or modify any data without knowing the encryption key or password. Full disk encryption provides a strong level of protection for data at rest, as it prevents data leakage or exposure in case of physical theft or loss of the device.
