For example, the following Action element applies to all IAM actions that include the string `AccessKey`, including `CreateAccessKey`, `DeleteAccessKey`, `ListAccessKeys`, and `UpdateAccessKey`:\n\n`\"Action\": \"iam:*AccessKey*\"`\n\nSome services let you limit the actions that are available.\nFor example, Amazon SQS lets you make available just a subset of all the possible Amazon SQS actions.\nIn that case, the `*` wildcard doesn't allow complete control of the queue; it allows only the subset of actions that you've shared.\n\n<https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_action.html>"

The ARN format depends on the AWS service and the specific resource.\nFor more information about ARNs, see: <https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_identifiers.html#identifiers-arns>\n\nSome AWS services do not support resource-level permissions. In those cases, use the wildcard character (`*`) in the Resource element.\n\nExamples:\n* Specific SQS queue:\n  `\"Resource\": \"arn:aws:sqs:us-east-2:account-ID-without-hyphens:queue1\"`\n* Specific IAM user (user name is case sensitive):\n  `\"Resource\": \"arn:aws:iam::account-ID-without-hyphens:user/Bob\"`\n\n# Using wildcards in resource ARNs\n\nYou can use wildcard characters (`*` and `?`) within the individual segments of an ARN (the parts separated by colons) to represent:\n- Any combination of characters (`*`)\n- Any single character (`?`)\n\nYou can use multiple `*` or `?` characters in each segment.\nIf the `*` wildcard is the last character of a resource ARN segment, it can expand to match beyond the colon boundaries.\nIt is recommended to use wildcards within ARN segments separated by a colon.\n\n**Note:** You can't use a wildcard in the service segment that identifies the AWS product.\n\n## Examples\n\nAll IAM users whose path is `/accounting`:\n```text\n\"Resource\": \"arn:aws:iam::account-ID-without-hyphens:user/accounting/*\"\n```\n\nAll items within a specific Amazon S3 bucket:\n```text\n\"Resource\": \"arn:aws:s3:::amzn-s3-demo-bucket/*\"\n```\n\nWildcards can match across slashes and other characters:\n```text\n\"Resource\": \"arn:aws:s3:::amzn-s3-demo-bucket/*/test/*\"\n```\nThis matches:\n- amzn-s3-demo-bucket/1/test/object.jpg\n- amzn-s3-demo-bucket/1/2/test/object.jpg\n- amzn-s3-demo-bucket/1/2/test/3/object.jpg\n- amzn-s3-demo-bucket/1/2/3/test/4/object.jpg\n- amzn-s3-demo-bucket/1///test///object.jpg\n- amzn-s3-demo-bucket/1/test/.jpg\n- amzn-s3-demo-bucket//test/object.jpg\n- amzn-s3-demo-bucket/1/test/\n\nBut does **not** match:\n- amzn-s3-demo-bucket/1-test/object.jpg\n- amzn-s3-demo-bucket/test/object.jpg\n- amzn-s3-demo-bucket/1/2/test.jpg\n\n## Specifying multiple resources\n\nYou can specify multiple resources in the `Resource` element by using an array of ARNs:\n```json\n\"Resource\": [\n    \"arn:aws:dynamodb:us-east-2:account-ID-without-hyphens:table/books_table\",\n    \"arn:aws:dynamodb:us-east-2:account-ID-without-hyphens:table/magazines_table\"\n]\n```\n\n## Using policy variables in resource ARNs\n\nYou can use JSON policy variables in the part of the ARN that identifies the specific resource. For example:\n```text\n\"Resource\": \"arn:aws:dynamodb:us-east-2:account-id:table/${aws:username}\"\n```\nThis allows access to a `DynamoDB` table that matches the current user's name.\n\nFor more information about JSON policy variables, see [IAM policy elements: Variables and tags](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_variables.html).\n\n<https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_resource.html>"
