To ensure data security while stored on a third-party cloud provider, encryption is the most effective method. AES (Advanced Encryption Standard) is used for encrypting data at rest, ensuring that stored information remains secure from unauthorized access. TLS (Transport Layer Security) protects data in transit, encrypting communication between the application and cloud storage to prevent interception or tampering.
These two methods provide comprehensive protection for both stored and transmitted data, maintaining confidentiality and integrity.
