Scenario: Your organization has multiple AWS accounts for different departments. How would you set up Cross-Account Access to allow a central security team to audit resources across all accounts?
- Create IAM roles with appropriate permissions in each account and establish trust relationships with the central security account.
- Enable AWS Organizations and configure cross-account access policies for the central security team.
- Share root account credentials with the central security team for direct access to all accounts.
- Use IAM users with cross-account access policies for each department to grant access to the central security team.
By creating IAM roles with the necessary permissions in each AWS account and establishing trust relationships with the central security account, you can enable the central security team to audit resources across all accounts securely.
What are the primary methods for granting Cross-Account Access in AWS?
- Access keys
- Bucket policies
- EC2 instance profiles
- IAM Roles and IAM users
IAM Roles and IAM users are the primary methods for granting Cross-Account Access in AWS.
How do you set up Cross-Account Access using IAM roles?
- Create IAM users
- Enable MFA
- Establish trust relationships between accounts
- Share access keys
To set up Cross-Account Access using IAM roles, you establish trust relationships between the accounts involved, allowing one account to assume roles in the other account.
What are the security considerations when implementing Cross-Account Access?
- Disable CloudTrail logging
- Ensure proper IAM permissions
- Share IAM passwords
- Use public access keys
Security considerations when implementing Cross-Account Access include ensuring that IAM permissions are properly configured to limit access to only the necessary resources and actions.
What are some best practices for managing permissions in Cross-Account Access scenarios?
- Grant unrestricted access
- Share IAM user credentials
- Use IAM roles with least privilege
- Utilize public key authentication
It's a best practice to use IAM roles with the least privilege necessary to perform the required tasks when managing permissions in Cross-Account Access scenarios. This reduces the risk of unintended access and potential security breaches.
How does AWS handle trust relationships in Cross-Account Access configurations?
- Trust is automatically granted to all accounts
- Trust is established through API calls
- Trust is managed through public key encryption
- Trust policies define which accounts can assume roles
In Cross-Account Access configurations, trust policies define which AWS accounts can assume IAM roles, specifying the trusted entities and their permissions.
What are the limitations or constraints of Cross-Account Access in AWS?
- Cannot grant access to resources outside AWS
- Limited to IAM users only
- Limited to a maximum of 10 accounts per role
- Restricted to specific AWS regions
Cross-Account Access allows access to AWS resources across accounts but does not extend access to resources outside of AWS.

When setting up Cross-Account Access, you establish a trust relationship between the source account and the trusted account.
IAM policies are used to define the permissions granted to the ________ account in a Cross-Account Access scenario.
- Access
- Primary

- Primary
- Source
- Target
To grant Cross-Account Access, the target account must explicitly allow access to the resources in its account through IAM policies.
