Use AWS Managed Policies for all team members, ensuring consistent and secure access to AWS services.

Create custom IAM roles with specific permissions for each team member based on their job function.

Implement a hybrid approach using both RBAC and ABAC, with RBAC defining high-level roles and ABAC handling fine-grained access control based on attributes such as time and location.

Rotate IAM credentials frequently to minimize the risk of unauthorized access.
