Overview of Mechanisms
We have all seen in the media numerous occurrences whereby large international organizations have had their data exposed and leaked that had been stored on S3. Any sensitive data stored in the cloud MUST be encrypted, and when storing your data on S3 there are multiple different options that you can choose from to enable you to protect your data with encryption. To help you understand these mechanisms, this course will guide you through the process of how each of them works, not just from an encryption perspective but also at a decryption level. This will allow you to make the right choice when it comes to selecting the most appropriate method of encryption to align with your own internal security strategy.
Applying encryption is a simple task and it can protect you and your customers from data exposure should a malicious user gain access to your S3 buckets.

By the end of this course series you will be able to explain the encryption and decryption process for:
- Server-Side Encryption with S3 Managed Keys (SSE-S3)
- Server-Side Encryption with KMS Managed Keys (SSE-KMS)
- Server-Side Encryption with Customer Provided Keys (SSE-C)
- Client-Side Encryption with KMS Managed Keys (CSE-KMS)
- Client-Side Encryption with Customer Provided Keys (CSE-C)
This course is intended for those who have the responsibility of storing, managing, and protecting data that is stored on Amazon S3.
This is an advanced level course and so it is essential that you have an understanding of S3 and that you have the knowledge to enable you to upload and retrieve data along with how to select different encryption options. In addition to this, you must also be familiar with the KMS service and understand both CMKs and Data encryption keys.
Server-Side Encryption with S3 Managed Keys, SSE-S3. The encryption process is as follows. Firstly, a client uploads Object Data to S3. S3 then takes this Object Data and encrypts it with an S3 Plaintext Data Key. This creates an encrypted version of the Object Data, which is then saved and stored on S3. Next, the S3 Plaintext Data Key is encrypted with an S3 Master Key. Which creates an encrypted S3 Data Key. This encrypted Data Key is then also stored on S3 and the Plaintext Data Key is removed from memory. The decryption process is as follows. A request is made by the client to S3 to retrieve the Object Data. S3 takes the associated encrypted S3 Data Key off the Object Data and decrypts it with the S3 Master Key. The S3 Plaintext Data Key is then used to decrypt the object data. This object data is then sent back to the client.
