Best practices for using AWS Identity and Access Management (IAM) include:
B. Create individual IAM users: Each user should have their own IAM credentials to ensure accountability, control, and traceability. Sharing credentials can lead to security risks and difficulty in auditing.
E. Use groups to assign permissions to IAM users: Assigning permissions through IAM groups simplifies permission management. You can assign the necessary permissions to the group, and then add or remove users from the group as needed, rather than managing permissions for each user individually.
Why other options are not suitable:
A. Share access keys: Sharing access keys is a security risk and violates AWS security best practices. Each user should have their own credentials.
C. Use inline policies instead of customer-managed policies: Customer-managed policies are preferred over inline policies because they offer better control, reusability, and versioning.
D. Grant maximum privileges to IAM users: Granting the least privilege necessary is a best practice to reduce the risk of accidental or malicious actions.
