By placing the authorized-users role in the KMS key resource policy, it further enforces the separation of duties so administrators in the account with an ability to modify IAM policies dont inadvertently escalate privilege to other IAM users/roles and give them permissions to use KMS keys for decryption. However, for some other customers, SSE-S3 may have met their requirements initially, but their requirements may have changed over time. Using server-side encryption with AWS Key Management Service (SSE-KMS Listing 2: secure-key-admin IAM policy Your policy will have an ARN (it will look something like arn:aws:iam::111122223333:policy/secure-key-admin). The account ID in which authorized-users role exists must be listed in the key policy. Valid values are " AES256 " and " aws:kms ". With SSE-KMS, there is an additional benefit of getting audit trails for CMKS which are used for encryption & also get details of users accessing these CMKs. In an effort to be concise, this policy grants all permissions to the KMS service and then denies certain rights through an explicit deny statement. Instead, you need the permission to decrypt the AWS KMS key. On the Step 1 screen, set a display name (called an Alias) for the key and a description.

Create a customer-managed KMS key to encrypt and decrypt the data in the S3 bucket you just created. This can be helpful for customers that find their compliance needs changing over time, as they must adhere to more stringent policies for data security. For more information, see Quotas in the Key to use for encrypting the state. An EC2 instance running with this role will be able to create and read encrypted data in the protected S3 bucket. For troubleshooting information about permissions when using Amazon S3 with Athena, see This approach is well-understood, documented, and widely implemented. Your policy will have an ARN (it will look something like arn:aws:iam::111122223333:policy/secure-bucket-access). You can see this by looking at the field ServerSideEncryption, which is set to "AES256.". Not really sure what to try. Pick, On the Step 4 screen, select key users. Customers who use Amazon Simple Storage Service (Amazon S3) often take advantage of S3-managed encryption keys (SSE-S3) for server-side object encryption (SSE). As the S3 service evolves over time and new features are added, the policy will permit using those new features, without any change to this policy. The EC2 instance hours are charged according to standard EC2 pricing. To use the Amazon Web Services Documentation, Javascript must be enabled. The explicit deny mechanism is important because, due to IAMs policy evaluation logic, an explicit deny cannot be overridden by subsequent allow statements or by attaching additional policies.
