A policy is an object in AWS that, when associated with an identity or resource, defines their permissions. AWS evaluates these policies when an IAM principal (user or role) makes a request. Permissions in the policies determine whether the request is allowed or denied. Most policies are stored in AWS as JSON documents.Teams. Q&A for work.

Resolution. You can prevent IAM entities from accessing the KMS key and allow the root user account to manage the key. This also prevents the root user account from losing access to the KMS key.See the example aws-auth.yaml file from Enabling IAM user and role access to your cluster. 7. Add designated_user to the mapUsers section of the aws-auth.yaml file in step 6, and then save the file. 8.

AWS Identity and Access Management (IAM) is a web service for securely controlling access to AWS services. With IAM, you can centrally manage users, security credentials such as access keys, and permissions that control which AWS resources users and applications can access.To allow users to assume the current role again within a role session, specify the role ARN or AWS account ARN as a principal in the role trust policy. AWS services that provide compute resources such as Amazon EC2, Amazon ECS, Amazon EKS, and Lambda provide temporary credentials and automatically rotate these credentials.If you have 2FA enabled. You need to generate session token using this command aws sts get-session-token --serial-number arn-of-the-mfa-device --token-code code-from-token. arn-of-the-mfa-device can be found in your profile, 2FA section. Token, is generated token from the device.EDIT: you'll need two "Resources" on the policy for it to do what you intend: arn:aws:s3:::bucketname and arn:aws:s3:::bucketname/*. Actions like GetObject or PutObject need the extra slash and asterisk for them to work (they work at the object level, not at the bucket level)Amazon Resource Names (ARNs) uniquely identify AWS resources. We require an ARN when you need to specify a resource unambiguously across all of AWS, such as in IAM policies, Amazon Relational Database Service (Amazon RDS) tags, and API calls. ARN format. The following are the general formats for ARNs.It is not possible to use wildcard in the trust policy except "Principal" : { "AWS" : "*" }.The reason being when you specify an identity as Principal, you must use the full ARN since IAM translates to the unique ID e.g. AIDAxxx (for IAM user) or AROAxxx (for IAM role). Go to IAM. Go to Roles. Choose Create role. When asked to select which service the role is for, select EC2 and choose Next:Permissions . You will change this to AWS Control Tower later. When asked to attach policies, choose AdministratorAccess. Choose Next:Tags. You may see an optional screen titled Add tags. The AWS secrets engine generates AWS access credentials dynamically based on IAM policies. This generally makes working with AWS IAM easier, since it does not involve clicking in the web UI.

AWS CLI: aws iam delete-virtual-mfa-device. AWS API: DeleteVirtualMFADevice."AWS": "arn:aws:iam::account_id:root" If you specify an Amazon Resource Name (ARN) for the principal, the ARN is transformed to a unique principal ID when the policy is saved. For example endpoint policies for gateway endpoints, see the following: Find your AWS account ID. You can find the AWS account ID using either the AWS Management Console or the AWS Command Line Interface (AWS CLI). In the console, the location of the account ID depends on whether you're signed in as the root user or an IAM user. The account ID is the same whether you're signed in as the root user or an IAM user.See the example aws-auth.yaml file from Enabling IAM user and role access to your cluster. 7.

AWS account root user – The request context contains the following value for condition key aws:PrincipalArn. When you specify the root user ARN as the value for the aws:PrincipalArn condition key, it limits permissions only for the root user of the AWS account. This is different from specifying the root user ARN in the principal element of a ...Using "Principal" : {"AWS" : "*" } with an Allow effect in a resource-based policy allows any root user, IAM user, assumed-role session, or federated user in any account in the same partition to access your resource.

To use an ARN, replace the italicized text with the resource-specific information. Be aware that the ARNs for some resources omit the Region, the account ID, or both the Region and the account ID. You can allow users from one AWS account to access resources in another AWS account. To do this, create a role that defines who can access it and what permissions it grants to users that switch to it. In this step of the tutorial, you create the role in the Production account and specify the Development account as a trusted entity. For example, a principal similar to arn:aws:iam::123456789012:root allows all IAM identities of the account to assume that role.
