Disk Encryption
Disk encryption is a security technique that encrypts data stored on a disk drive, such as a hard drive or SSD, to protect it from unauthorized access. It works by converting data into an unreadable format using cryptographic algorithms, which can only be decrypted with the correct key or password. This ensures that even if the physical storage device is lost, stolen, or accessed without authorization, the data remains secure and confidential.
Developers should learn and use disk encryption to protect sensitive data in applications involving personal information, financial records, or intellectual property, especially in compliance with regulations like GDPR or HIPAA. It is essential for securing laptops, servers, and cloud storage in scenarios such as remote work, data breaches, or when handling confidential client data, as it provides a strong layer of defense against physical theft or unauthorized access.
