Details for Object Storage, Archive Storage, and Data Transfer

This topic covers details for writing policies to control access to Archive Storage, Object Storage, and Data Transfer.

Tip

The object lifecycle policies feature requires that you grant permissions to the Object Storage service to archive and delete objects on your behalf. See Using Object Lifecycle Policies for more information.

Resource-Types

Individual Resource-Types

objectstorage-namespaces

buckets

objects

Aggregate Resource-Type

object-family

A policy that uses <verb> object-family is equivalent to writing one with a separate <verb> <individual resource-type> statement for each of the individual resource-types.

See the table in Details for Verb + Resource-Type Combinations for details of the API operations covered by each verb, for each individual resource-type included in object-family.

Supported Variables

Object Storage supports all the general variables (see General Variables for All Requests), plus the ones listed here:


Operations for This Resource-Type...	Can Use This Variable	Variable Type	Comments
`buckets` and `objects`	`target.bucket.name`	String	Use this variable to control access to a specific bucket. For an example policy, see Let users write objects to Object Storage buckets. Important: Condition matching is case insensitive. If you have a bucket named "BucketA" and a bucket named "bucketA", the condition `where target.bucket.name="BucketA"` applies to both. To avoid potential issues with resource names in policy, give your resources distinct names.
`buckets` and `objects`	`target.bucket.tag.<TagNamespace>.<TagKeyDefinition>`	String	Use this variable to control access to the buckets that have the specific tag. See Let users write objects to Object Storage buckets. Important: You cannot use this variable for `CreateBucket` operations and operations that involve multiple buckets such as `ListBucket`.

Note

The request.ipv4.ipaddress and the request.vcn.id variables are deprecated. Instead of using these variables, create a network source to specify either an IP address range or a specific VCN ID. You can then use the network source in your policy to restrict access to only requests coming from the allowed networks. For more information, see Overview of Network Sources.

Details for Verb + Resource-Type Combinations

The following tables show the permissions and API operations covered by each verb. The level of access is cumulative as you go from inspect > read > use > manage. For example, a group that can use a resource can also inspect and read that resource. A plus sign (+) in a table cell indicates incremental access compared to the cell directly above it, whereas "no extra" indicates no incremental access.

read	INSPECT + OBJECT_READ	INSPECT + `GetObject`	none
use	READ + OBJECT_OVERWRITE	READ + `ReencryptObject`	READ + `PutObject` (USE allows `PutObject` to overwrite existing objects, but creating a new object also requires OBJECT_CREATE) `CreateMultipartUpload`, `UploadPart`, `CommitMultipartUpload` (these operations also need `manage objects`)

data-transfer-jobs

Policies for data transfer jobs also require either manage objects or manage objects and manage buckets. See Creating the Required IAM Users, Groups, and Policies for details.

inspect	TRANSFER_JOB_INSPECT	no customer-facing API	no customer-facing API

Permissions Required for Each API Operation

The following table lists the API operations in a logical order, grouped by resource type.

For information about permissions, see Permissions.


API Operation	Permissions Required to Use the Operation
`GetNamespace`	API requires no permissions and returns the caller's namespace. Use the API to validate your credentials. OBJECTSTORAGE_NAMESPACE_READ permission is required if you include the optional `compartmentId` parameter. Use the `compartmentId` parameter to determine the namespace for a third-party tenancy.
`GetNamespaceMetadata`	OBJECTSTORAGE_NAMESPACE_READ
`UpdateNamespaceMetadata`	OBJECTSTORAGE_NAMESPACE_UPDATE
`CreateBucket`	BUCKET_CREATE
`UpdateBucket`	BUCKET_UPDATE
`GetBucket`	BUCKET_READ
`HeadBucket`	BUCKET_INSPECT
`ListBuckets`	BUCKET_INSPECT
`DeleteBucket`	BUCKET_DELETE
`ReencryptBucket`	BUCKET_UPDATE
`PutObject`	The permission required depends on whether or not the object already exists in the bucket: OBJECT_CREATE is required when an object with that name does not already exist in the bucket. OBJECT_OVERWRITE is required when an object with that name already exists in the bucket.
`RenameObject`	OBJECT_CREATE and OBJECT_OVERWRITE
`GetObject`	OBJECT_READ
`HeadObject`	OBJECT_READ or OBJECT_INSPECT
`DeleteObject`	OBJECT_DELETE
`DeleteObjectVersion`	OBJECT_VERSION_DELETE
`ListObjects`	OBJECT_INSPECT
`ReencryptObject`	OBJECT_READ & OBJECT_OVERWRITE
