What is the purpose of setting a password & permissions on the IAM role during cross account configuration?
The purpose of setting permissions on an IAM role during cross-account configuration is to control access to AWS resources securely and effectively. While IAM roles do not have passwords, the permissions defined for the role are critical for ensuring that only authorized actions are allowed when the role is assumed. This setup enhances security, adheres to the principle of least privilege, and provides granular control over resource access in cross-account scenarios.
Why cross account access is used when working with multiple aws accounts?
Cross-account access is essential for organizations using multiple AWS accounts as it enhances security, facilitates resource sharing, supports compliance, and provides flexibility in managing access. It allows teams to collaborate effectively while maintaining control over their resources and ensuring that security best practices are followed.
What key elements must be configured in account 1 to allow another aws account to access its s3 bucket?
The key elements that must be configured in Account 1 to allow another AWS account to access its S3 bucket include:
1. A bucket policy that grants access to the principal from Account 2.
2. An IAM role or user in Account 2 with the necessary permissions.
3. A trust policy (if using a role) that allows the role to be assumed by users or services in Account 1.
4. A permissions policy for the role/user in Account 2 that allows the necessary S3 actions.
Why is it important to include the principal element in the IAM role trust policy for cross account access?
The Principal element in an IAM role trust policy is essential for defining who can assume the role, establishing trust relationships, enhancing security, and enabling granular access management. It plays a critical role in ensuring that cross-account access is both secure and controlled.
How does an IAM role help enable cross account access between aws accounts?
IAM roles facilitate secure and controlled cross-account access by allowing users and services to assume roles in other AWS accounts, enabling them to perform actions based on the permissions granted by those roles.
