AWS PostgreSQL IAM Authentication | All About

Did you know that IAM Database Authentication allows us to use AWS IAM roles to authenticate to our PostgreSQL database?

Furthermore, it offers an extra layer of security and simplifies database access management.

Let’s take a look at how AWS PostgreSQL IAM Authentication works:

• It allows us to create IAM roles and policies that define the permissions and access privileges required for users, applications, or services to interact with the PostgreSQL database.
• Once we enable IAM Authentication we can associate an IAM role with a database user in our PostgreSQL instance. This allows anyone in the IAM role to access the database.
• According to our experts, when a user starts a connection to the PostgreSQL database with IAM Authentication enabled, they use their IAM credentials to request temporary database credentials from AWS STS.
• AWS STS offers temporary credentials that include an authentication token, expiration time, etc.
• The authentication token is sent with the connection request to the PostgreSQL instance. The PostgreSQL server validates the token with AWS to confirm its authenticity and validity.
• Furthermore, access to the PostgreSQL instance is controlled by the IAM roles and policies defined in AWS IAM. Users and applications can only access the database resources for which they have been granted permission through IAM.

Benefits of AWS PostgreSQL IAM Authentication

Some of the benefits offered by IAM include:

• Simplified Management
• Better Security
• Better integration with IAM
• Temporary Credentials for better security

How to authenticate & access PostgreSQL database instance with AWS IAM credentials

1. First, we have to launch the PostgreSQL instance with IAM auth enabled.
2. Then, we must create IAM auth user with rds_iam role. This allows the IAM user to use IAM authentication to access the database.
3. Next, we have to add a new policy for IAM access.
4. After that, we have to request temporary credentials and use them as DB user passwords.
