Cryptography in Data Storage and Cloud Security
Cryptography protects sensitive data stored locally or in the cloud.
-
Disk Encryption:
- Tools like BitLocker and VeraCrypt encrypt entire disks or volumes to secure data at rest.
- Encrypted disks prevent unauthorized access even if the physical hardware is stolen.
-
Cloud Encryption:
- Cloud service providers encrypt data stored on their servers and during transit.
- Zero-knowledge encryption ensures that even service providers cannot access user data.
-
Database Encryption:
- Databases storing sensitive information, such as customer details, are encrypted to prevent unauthorized access.
- Transparent Data Encryption (TDE) is commonly used in enterprise systems.
