Excluded and conditional actions

No patterns are excluded by NotAction or Deny statements.

Resource scope and attachment

Resource scope across granted actions: all-resources.

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

Why this tier

Grants 2 write, tagging or permissions-management actions, short of full control of any service.
2 granted write or permissions-management actions have no data-plane classification from AWS, so the data-plane rule cannot assess them.
