Protecting data is one of the most important parts of cloud security. Cloud platforms offer encryption tools for data storage and communication.

Key Concepts:

• Data at Rest Encryption: Encryption at rest protects information stored in databases and storage services. Even if an attacker gains access to the physical drives the encrypted data remains protected. This is critical for sensitive or regulated data.
• Data in Transit Encryption: Encryption in transit protects data traveling between services networks and users. This prevents attackers from capturing readable information during communication.
• Key Management: Key management systems create store and rotate encryption keys. Customers can use provider managed keys or customer managed keys depending on their security needs. Proper key lifecycle management prevents unauthorized decryption.
