Data encryption in cloud is a security method that converts readable data into an unreadable format using cryptographic algorithms. Only authorized users with the correct decryption keys can access the original data.
- Protects sensitive and confidential information
- Prevents data theft and unauthorized access
- Helps meet compliance requirements (ISO, GDPR, HIPAA)
- Secures data stored and transmitted over the internet
Encrypts data stored in cloud services such as:
- Databases
- Storage buckets
- Virtual machine disks
Encrypts data while moving between:
- Users and cloud applications
- Cloud services and databases
- Internal cloud services
Mathematical method used to encrypt data (e.g., AES-256, RSA).
Secret values used to encrypt and decrypt data.
Cloud service that securely stores and manages encryption keys.
Used for SSL/TLS encryption for secure communication.
- User uploads or sends data to cloud
- Cloud encrypts data using encryption key
- Encrypted data is stored or transmitted
- When accessed, data is decrypted using the key
- Only authorized users can read the data
- Enable encryption by default for all services
- Use strong encryption standards (AES-256)
- Store keys securely in KMS
- Rotate encryption keys regularly
- Use HTTPS for all applications
A company stores customer records in a cloud database and wants to protect the data using encryption.
- Create a master encryption key:
CustomerDataKey
- Set key access permissions for admins only
- Create an RDS database
- Enable encryption using
CustomerDataKey
- Enable SSL/TLS for database connections
- Configure application to connect using HTTPS/SSL
- Enable automatic encrypted backups
- Store snapshots with encryption enabled
- Only authorized IAM users can decrypt and access data
- Customer records are stored in encrypted format
- Even if storage is compromised, data remains unreadable
- Data is securely transmitted over encrypted connections
- Strong protection of sensitive customer data
- Compliance with security standards
- Reduced risk of data breaches
Data encryption in cloud ensures:
- Secure storage and transmission of data
- Protection from unauthorized access
- Compliance with security regulations
- Trusted and secure cloud operations
