How to Name Tags?
Take note of the below while naming IAM roles, IAM users, STS federated user sessions and STS assume-role sessions:
- Tag keys and values of tags are capable of having spaces, letters, numbers and the following symbols: _ . : / = + – @ .
- Tag key–value pairs: not case sensitive but preserved so as to not be able to include different Apartment and apartment tag keys.
- Tag values or tag keys cannot start with the text aws:. (it’s only for internal use).
- A tag can have empty values like pageNumber= “ ” . Tag keys are not capable of being empty.
- 1 tag cannot have various different values. It is possible to get a custom multi-value structure in that 1 value.
How to Apply and Edit Tags?
Take note of the below while attaching tags to roles or users:
- Roles and users can be tagged, while policies or groups cannot.
- Tag Editor cannot be used for tagging IAM entities, because it does not support IAM tags.
- Specific permissions are needed for tagging IAM entity, and permissions to list tas are needed for tagging or untagging users and roles.
- There are limits to the size and number of tags being attached to a user or role.
- Various IAM entities can get the exact same tag.
- More than 1 instance of the same tag key may not be given to an IAM entity.
- For the sake of editing a tag attached to an IAM role or user, you will need to get a new value tag attached for the sake of overwriting the already existing one.
What are the Permissions needed to Tag IAM Entities?
1 or every single one of the below IAM tag actions can be defined in an IAM policy:
- iam:TagUser
- iam:ListRoleTags
- iam:UntagRole
- iam:TagRole
- iam:UntagUser
- iam:ListUserTags
Allowing IAM entity: adding, listing, or removing a tag of a particular user
Get the below statement added to the permissions policy for IAM entity which requires managing tags. Rely on your very own account number and enter the user’s name instead of <username>.
{
"Effect": "Allow",
"Action": [
"iam:ListUserTags",
"iam:TagUser",
"iam:UntagUser"
],
"Resource": "arn:aws:iam:*:<account-number>:user/<username>"
}
Allowing IAM user the option of self-managing tags
Add Get the below statement added to the permissions policy of users for giving them the ability of managing their very own tags.
{
"Effect": "Allow",
"Action": [
"iam:ListUserTags",
"iam:TagUser",
"iam:UntagUser"
],
"Resource": "arn:aws:iam:*:user/${aws:username}"
}
Add Get the below statement added to the permissions policy of IAM entity which requires adding, but not removing, tags of a prticular user.Allowing IAM entity the addition of a tag to a particular user
Keep in Mind
iam:AddRoleTags + iam:AddUserTags actions: need the ddition of the iam:ListRoleTags and iam:ListUserTags actions.
For the sake of utilizing the policy, enter the user’s name instead of <username>.
{
"Effect": "Allow",
"Action": [
"iam:ListUserTags",
"iam:TagUser"
],
"Resource": "arn:aws:iam:*:<account-number>:user/<username>"
}
Allowing IAM entity to list, add or remove tags for a paticular role
Define the below statement to permissions policy for IAM entity for managing tags. Write the role’s name in the place of <rolename>.
{
"Effect": "Allow",
"Action": [
"iam:ListRoleTags",
"iam:TagRole",
"iam:UntagRole"
],
"Resource": "arn:aws:iam:*:<account-number>:role/<rolename>"
}
Otherwise, you’re capable of utilizing a managed policy (example: IAMFullAccess) for giving total access to IAM.
