How To Rotate Your RDS Key Securely: A Step-By-Step Guide

rds rotate key

In the world of cloud computing, security is a paramount concern. One critical aspect of ensuring the security of your Amazon Relational Database Service (RDS) is to regularly rotate the keys used to access the service. Key rotation is a security best practice that mitigates the risk associated with compromised credentials. This guide will walk you through the process of rotating your RDS key securely, using tools and services available within AWS. We will also touch upon how APIPark can simplify this process.

Introduction to RDS Key Rotation

Amazon RDS uses a key to encrypt and decrypt data at rest. This key, known as the RDS key, is stored in AWS Key Management Service (KMS). Regularly rotating this key is crucial for maintaining the security of your data. The process involves creating a new key and updating the RDS instance to use this new key without disrupting the ongoing operations.

Why Rotate Your RDS Key?

Security: Regular rotation reduces the window of opportunity for attackers who may have obtained your key.
Compliance: Many regulations require regular key rotation as a security measure.
Best Practice: It is a recommended practice by AWS and other security experts.

Step-by-Step Guide to Rotating Your RDS Key

Step 1: Create a New Key in AWS KMS

The first step is to create a new key in AWS KMS. Here’s how you can do it:

Log in to the AWS Management Console.
Navigate to the AWS KMS service.
Click on "Create key."
Choose the key type (e.g., customer managed key) and specify the key description and key usage.
Add the necessary permissions and tags.
Click "Create key."

Step 2: Update the RDS Instance to Use the New Key

After creating the new key, you need to update your RDS instance to use it:

Go to the Amazon RDS console.
Select the RDS instance you want to update.
Click on "Modify."
In the "DB instance class" section, find the "DB encryption" option.
Select the new key from the dropdown menu.
Click "Modify."

Step 3: Verify the Key Rotation

It is important to verify that the key rotation has been successful:

Check the RDS instance details to ensure the new key is in use.
Optionally, you can enable encryption monitoring to track key usage.

Step 4: Schedule Regular Key Rotation

To maintain a high level of security, it is advisable to schedule regular key rotations:

Use AWS CloudWatch Events to create a rule that triggers a Lambda function.
Write a Lambda function that automates the key rotation process.
Set the frequency of the event (e.g., every 90 days).
