Resource scope and attachment

Resource scope across granted actions: all-resources.

Can be attached: Yes, to users, groups and roles.

Why this tier

  • Grants only List and Read actions.

Guidance

Practical scope

One statement allows ram:Get* and ram:List* on Resource "*", with no Condition. The AWS RAM User Guide says it grants permission to run any of the Get* or List* operations and does not provide any ability to modify any resource share.

Use cases

  • View details about the resource shares that are owned by your AWS account.

Best practices

  • AWS managed policies don't grant least privilege permissions. The IAM User Guide suggests using IAM Access Analyzer to see which permissions principals actually use, then writing a custom policy or generating one with only the required permissions.

Security considerations

  • ram:Get* and ram:List* apply to all resources, so principals can view details of every resource share the account owns.
  • You cannot change the permissions in an AWS managed policy. If AWS updates the policy, the update affects every user, group and role it is attached to.

Assignment guidance

You can attach this policy to your users, groups and roles. The reference page also links to guidance on creating a permission set using AWS managed policies in IAM Identity Center. It fits where viewing AWS RAM resource shares is the only requirement.

Frequently asked questions

When should I attach AWSResourceAccessManagerReadOnlyAccess?
The AWS RAM User Guide says you can attach it to your IAM identities to give read-only permissions to the resource shares owned by your account. Use it for people who only need to view resource shares.
What does AWSResourceAccessManagerReadOnlyAccess grant?
It allows ram:Get* and ram:List* on all resources. The AWS RAM User Guide says it does not provide any ability to modify any resource share.
What are the security risks of AWSResourceAccessManagerReadOnlyAccess?
The grant is limited to ram:Get* and ram:List* but covers all resources, so everything about the account's resource shares is visible to the holder. AWS managed policies do not grant least privilege permissions, and an AWS update to the policy affects every identity it is attached to.
