Security best practices
Use AWS Identity and Access Management (IAM) accounts to control access to API operations, especially operations that create, modify, or delete resources. For the API, such resources include projects, campaigns and journeys.
Create an individual user for each person who manages resources, including yourself. Don't use AWS root credentials to manage resources.
Grant each user the minimum set of permissions required to perform his or her duties.
Use IAM groups to effectively manage permissions for multiple users.
Rotate your IAM credentials regularly.
