Rule: DynamoDB Table Should Have Encryption Enabled

Ensure DynamoDB table has encryption enabled for enhanced security measures.

Rule	DynamoDB table should have encryption enabled
Framework	NIST 800-171 Revision 2
Severity	✔ Low

Rule Description

The rule states that the DynamoDB table should have encryption enabled to meet the compliance requirements of NIST 800-171 Revision 2. Encryption provides an additional layer of security by transforming the data stored in the DynamoDB table into an unreadable format, which can only be decrypted using the appropriate encryption key.

Troubleshooting Steps

If encryption is not enabled for the DynamoDB table, you may encounter the following issues:

1.

Non-compliance: Failure to enable encryption for the DynamoDB table will lead to non-compliance with the NIST 800-171 Revision 2 security requirements.

2.

Data exposure: Without encryption, sensitive data stored in the table may be accessible to unauthorized individuals in case of a security breach.

Necessary Codes

To enable encryption for the DynamoDB table, you need to modify the table properties using the appropriate programming language or AWS CLI commands.

Here is an example of using AWS CLI to enable encryption for an existing DynamoDB table (replace

table-name

with the actual name of your table):

aws dynamodb update-table \
  --table-name table-name \
  --sse-specification Enabled=true \
  --sse-type KMS \
  --sse-kms-key-id <KMS-KEY-ID>

In the above command, the

--sse-specification Enabled=true

enables encryption,

--sse-type KMS

specifies the Key Management Service (KMS) as the encryption type, and

--sse-kms-key-id

provides the ID of the KMS key to be used for encryption.

Step-by-Step Guide for Remediation

Follow these step-by-step instructions to enable encryption for a DynamoDB table:

1.

Identify the DynamoDB table that needs encryption enabled. Ensure that you have the necessary permissions to modify the table settings.

2.

Determine the Key Management Service (KMS) key that will be used for encryption. Make sure the KMS key has the appropriate level of security and complies with the requirements of NIST 800-171 Revision 2.

3.

Open a command-line interface or terminal window.

4.

Authenticate using the AWS CLI with appropriate credentials that have the necessary permissions to modify the DynamoDB table.

5.
Run the following command to enable encryption for the DynamoDB table (replace
```
table-name
```
and
```
<KMS-KEY-ID>
```
with their respective values):

aws dynamodb update-table \
  --table-name table-name \
  --sse-specification Enabled=true \
  --sse-type KMS \
  --sse-kms-key-id <KMS-KEY-ID>

1.

Wait for the command to execute successfully. Once completed, the DynamoDB table will have encryption enabled using the specified KMS key.

2.

Verify the encryption status by checking the table settings or running a command to retrieve the table details.

3.

Ensure that the encryption process does not impact any existing application workflows or access patterns. Conduct thorough testing to ensure the applications can still access and modify the data in the encrypted DynamoDB table.

4.

Document the encryption configuration for future reference and compliance audits.

By following these steps, encryption can be successfully enabled for the DynamoDB table, ensuring compliance with the NIST 800-171 Revision 2 requirements.
