Encryption

1. Encryption on fly (SSL)

   • Data encrypted before sending and decrypted when received by the server
   • To protect against the MIMD (Man in the Middle Attack)
   • SSL certificates help to secure HTTPS

2. Server side encryption at rest

   • Data is encrypted after being received by the server
   • Data decrypted before being sent
   • It is stored in an encrypted form thanks to key (usually a data key)

3. Client side encryption

   • Data encrypted by the client and never decrypted by the server

• SSE-S3
• SSE-KMS
• SSE-C
• Client Side Encyption
• Encyption in tansit (SSL)
