Details for Object Storage and Archive Storage

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

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 and Patterns	Use this variable to control access to a specific bucket. 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`.
`objects`	`target.object.name`	String and Patterns	Use this variable to control access to a specific object or object patterns.

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.

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 find the namespace for a third-party tenancy.
`GetNamespaceMetadata`	OBJECTSTORAGE_NAMESPACE_READ
`UpdateNamespaceMetadata`	OBJECTSTORAGE_NAMESPACE_UPDATE
`CreateBucket`	BUCKET_CREATE If the KMS Key ID is provided to the operation, the following additional permissions are required: KEY_ASSOCIATE The objectstorage-<location> subject must also have: KEY_ENCRYPT, KEY_DECRYPT, KEY_READ.
`UpdateBucket`	BUCKET_UPDATE For a customer-managed key encrypted bucket, the objectstorage-<location> subject must also have: KEY_ENCRYPT, and KEY_DECRYPT.
`GetBucket`	BUCKET_READ For a customer-managed key encrypted bucket, the objectstorage-<location> subject must have KEY_DECRYPT.
`HeadBucket`	BUCKET_INSPECT For a customer-managed key encrypted bucket, the objectstorage-<location> subject must have KEY_DECRYPT.
`ListBuckets`	BUCKET_INSPECT
`DeleteBucket`	BUCKET_DELETE
`ReencryptBucket`	BUCKET_UPDATE The objectstorage-<location> subject must also have: KEY_ENCRYPT, and KEY_DECRYPT.
`PutObject`	The permission required depends on whether the object already exists in the bucket: OBJECT_CREATE is required when an object with that name doesn't already exist in the bucket. OBJECT_OVERWRITE is required when an object with that name already exists in the bucket. For a customer-managed key encrypted bucket, the objectstorage-<location> subject must have KEY_ENCRYPT.
`RenameObject`	OBJECT_CREATE and OBJECT_OVERWRITE
`GetObject`	OBJECT_READ For a customer-managed key encrypted bucket, the objectstorage-<location> subject must have KEY_DECRYPT.
`HeadObject`	OBJECT_READ or OBJECT_INSPECT For a customer-managed key encrypted bucket, the objectstorage-<location> subject must have KEY_DECRYPT.
`DeleteObject`	OBJECT_DELETE
`DeleteObjectVersion`	OBJECT_VERSION_DELETE
`ListObjects`	OBJECT_INSPECT
`ListObjectVersions`	OBJECT_INSPECT
`ReencryptObject`	OBJECT_READ, OBJECT_OVERWRITE For a customer-managed key encrypted bucket, the following permissions are required: KEY_ASSOCIATE Additionally, the objectstorage-<location> subject must also have KEY_ENCRYPT, KEY_DECRYPT, and KEY_READ.
`RestoreObjects`	OBJECT_RESTORE
`UpdateObjectStorageTier`	OBJECT_UPDATE_TIER
`CreateMultipartUpload`	OBJECT_CREATE and OBJECT_OVERWRITE For a customer-managed key encrypted bucket, the objectstorage-<location> subject must have KEY_ENCRYPT.
`UploadPart`	OBJECT_CREATE and OBJECT_OVERWRITE For a customer-managed key encrypted bucket, the objectstorage-<location> subject must have KEY_ENCRYPT.
`CommitMultipartUpload`	BUCKET_READ, OBJECT_CREATE, OBJECT_READ, and OBJECT_OVERWRITE

`ListPreauthenticatedRequests`	PAR_MANAGE or BUCKET_READ
`DeletePreauthenticatedRequest`	PAR_MANAGE
`PutObjectLifecyclePolicy`	BUCKET_UPDATE, OBJECT_CREATE, and OBJECT_DELETE Additionally, the objectstorage-<location> subject must also have: BUCKET_INSPECT, BUCKET_READ, OBJECT_INSPECT. If the bucket the lifecycle policy applies to is a customer-managed key encrypted bucket then the objectstorage-<location> subject must also have: KEY_ENCRYPT, and KEY_DECRYPT. If the `PutObjectLifeCyclePolicy` operation also updates the object tier for example, from default to INFREQUENT_ACCESS, the user and the objectstorage-<location> subject must be granted OBJECT_UPDATE_TIER permission.
`GetObjectLifecyclePolicy`	BUCKET_READ For a customer-managed key encrypted bucket, the objectstorage-<location> subject must have KEY_DECRYPT.
`DeleteObjectLifecyclePolicy`	BUCKET_UPDATE For a customer-managed key encrypted bucket, the objectstorage-<location> subject must also have: KEY_ENCRYPT, and KEY_DECRYPT.
`CreateRetentionRule`	BUCKET_UPDATE and RETENTION_RULE_MANAGE (and RETENTION_RULE_LOCK) For a customer-managed key encrypted bucket, the objectstorage-<location> subject must also have: KEY_ENCRYPT, and KEY_DECRYPT.
`GetRetentionRule`	BUCKET_READ
`ListRetentionRule`	BUCKET_READ
`UpdateRetentionRule`	BUCKET_UPDATE and RETENTION_RULE_MANAGE (and RETENTION_RULE_LOCK) For a customer-managed key encrypted bucket, the objectstorage-<location> subject must also have: KEY_ENCRYPT, and KEY_DECRYPT.
`DeleteRetentionRule`	BUCKET_UPDATE and RETENTION_RULE_MANAGE For a customer-managed key encrypted bucket, the objectstorage-<location> subject must also have: KEY_ENCRYPT, and KEY_DECRYPT.
`CopyObjectRequest`	OBJECT_READ, and the second user permission required depends on whether the object already exists in the bucket: OBJECT_CREATE is required when an object with that name doesn't already exist in the bucket. OBJECT_OVERWRITE is required when an object with that name already exists in the bucket. Additionally, the objectstorage-<location> subject requires OBJECT_READ. For a customer-managed key encrypted bucket, the objectstorage-<location> subject must also have KEY_ENCRYPT, KEY_DECRYPT.
`GetWorkRequest`	OBJECT_READ
`ListWorkRequests`	OBJECT_INSPECT
`CancelWorkRequest`	OBJECT_DELETE
`CreateReplicationPolicy`	OBJECT_READ, OBJECT_CREATE, OBJECT_OVERWRITE, OBJECT_INSPECT, OBJECT_DELETE, OBJECT_RESTORE, BUCKET_READ, and BUCKET_UPDATE The objectstorage-<location> subject must have the same permissions as the user.
`GetReplicationPolicy`	BUCKET_READ
`DeleteReplicationPolicy`	OBJECT_READ, OBJECT_CREATE, OBJECT_OVERWRITE, OBJECT_INSPECT, OBJECT_DELETE, OBJECT_RESTORE, BUCKET_READ, and BUCKET_UPDATE
