Which solution is commonly used on Microsoft Windows computers to protect data at rest?

BitLocker is a security feature available in Microsoft Windows that is designed to protect data at rest by using encryption. When enabled, BitLocker encrypts the entire disk drive, which means that the data stored on the disk is rendered unreadable to unauthorized users. This level of protection is particularly important for laptops and portable devices that might be lost or stolen, ensuring that sensitive information remains secure even if the physical device falls into the wrong hands.

The encryption provided by BitLocker is based on the AES (Advanced Encryption Standard) algorithm, which is widely regarded as a secure method for protecting data. By requiring a user to authenticate before accessing the data, BitLocker adds an additional layer of security.

This solution is specifically designed for data at rest, while other options serve different purposes. For instance, TLS is used to secure data in transit over networks, IPSec secures Internet Protocol communications by encrypting data at the IP layer, and SGX provides hardware-based security for applications by enclosing code and data in a protected area of memory.

By using BitLocker, organizations and individuals can effectively safeguard sensitive data stored on Windows computers against data breaches and unauthorized access.
