AWS RDS for MariaDB

Rotating Admin/Regular AWS MariaDB Database Users with Keeper

Overview

In this guide, you'll learn how to rotate passwords for AWS MariaDB Database User and Admin accounts on your AWS environment using Keeper Rotation. RDS for MariaDB is an AWS managed resource where the MariaDB Admin Credentials are defined in the PAM Database record type and the configurations of the MySQL Users are defined in the PAM User record type.

For Amazon RDS, the AWS SDK will be used to rotate the password of Database Admin Accounts. To rotate the passwords of Regular Database Users, Keeper connects to the DB instance with the provided admin credentials and executes the necessary SQL statements to change the password.

Prerequisites

This guide assumes the following tasks have already taken place:

• Keeper Secrets Manager is enabled for your role
• Keeper Rotation is enabled for your role
• A Keeper Secrets Manager application has been created
• A Keeper Rotation gateway is already installed, running, and is able to communicate with your AWS MariaDB Database
• Your AWS environment is configured per our documentation

1. Set up PAM Database Record

The PAM Database record contains the admin credentials and necessary configurations to connect to the MariaDB RDS instance on AWS. Keeper Rotation will use these provided configurations to rotate passwords of regular database user accounts in the MariaDB RDS instance. These provided admin credentials need to also have sufficient database permissions to successfully change the credentials of the database user accounts.

The following table lists all the required fields on the PAM Database Record:

Field	Description
Title	Keeper record title Ex: AWS MariaDB Admin
Hostname or IP Address	The RDS Endpoint i.e. rdsdb.ckivswes.us-east-2.rds.amazonaws.com
Port	The RDS Port, for default ports see port mapping i.e. 3306
Use SSL	Check to perform SSL verification before connecting, if your database has SSL configured
Login	Admin account username that will perform rotation
Password	Admin account password
Database ID	The AWS DB instance ID
Database Type	mariadb
Provider Region	The region your Amazon RDS instance is using. i.e us-east-2

Note: Adding Provider Region and Database ID will enable managing the PAM Database Record through the SDK.

This PAM Database Record with the admin credential needs to be in a shared folder that is shared to the KSM application created in the pre-requisites. Only the KSM application needs access to this privileged account, it does not need to be shared with any users

2. Set up PAM Configuration

Note: You can skip this step if you already have a PAM Configuration set up for this environment.

If you are creating a new PAM Configuration, login to the Keeper Vault and select "Secrets Manager", then select the "PAM Configurations" tab, and click on "New Configuration".

The following table lists all the required fields on the PAM Configuration Record:

Field	Description
Title	Configuration name, example: AWS RDS Configuration
Environment	Select: AWS
Gateway	Select the Gateway that is configured on the Keeper Secrets Manager application and has network access to your MariaDB RDS Instance
Application Folder	Select the Shared folder where the PAM Configuration will be stored. We recommend placing this in a shared folder with the PAM User records, not the database resources.
AWS ID	A unique ID for this instance of AWS. This is for your reference and can be anything, but its recommended to be kept short Ex: AWS-1
Access Key ID	Set this field to USE_INSTANCE_ROLE if you are using EC2 role policy (default). Otherwise use a specific Access Key ID.
Access Secret Key	Set this field to USE_INSTANCE_ROLE if you are using EC2 role policy (default). Otherwise use a specific Secret Access Key.

For more details on all the configurable fields in the PAM Configuration record, visit this page.

3. Set up PAM User Records

Keeper Rotation will use the credentials in the PAM Database record to rotate the PAM User records on your AWS environment. The PAM User credential needs to be in a shared folder that is shared to the KSM application created in the prerequisites.

The following table lists all the required fields on the PAM User record:

Field	Description
Title	Keeper record title i.e. AWS DB User 1
Login	Case sensitive username of the account being rotated. If the user in the DB user table is in a Host other than %, add the Host value to the user name as USERNAME@HOST
Password	Account password is optional, rotation will set one if blank

4. Configure Rotation on the PAM User records

Select the PAM User record(s) from Step 3, edit the record and open the "Password Rotation Settings".

• Select the desired schedule and password complexity.

• The "Rotation Settings" should use the PAM Configuration setup previously.

• The "Resource Credential" field should select the PAM Database credential setup from Step 1.

• Upon saving, the rotation button will be enabled and available to rotate on demand, or via the selected schedule.

Any user with edit rights to a PAM User record has the ability to setup rotation for that record.
