Database Security

Using IAM

In this approach the IAM user should have appropriate policies and permissions. Granting of such permissions is decided by the account holder or the super user who grants these permissions.

Using VPC

You either use a VPC security group or DB security group to decide which EC2 instances can open connections to the endpoint and port of a DB instance. These connections can also be made using SSL.

Using IAM Database Authentication

In this approach you use a IAM role and an authentication token. The authentication token generates a unique value which is relevant to the IAM role that is used in the access process. Here the same set of credentials are used for database as well as other aws resources, like EC2 and S3 etc.
