Generating audit logs is only half the job, so Ozone also provides AuditParser - a sqllite based command line utility to parse/query audit logs with predefined templates(ex. Similarly, the audit of WRITE operations can be controlled using. To enable/disable audit of READ operations, set to NEUTRAL or DENY respectively. Ozone audit leverages the Marker feature which enables user to selectively audit only READ or WRITE operations by a simple config change without restarting the service(s). Ozone provides ability to audit all read & write operations to OM, SCM and Datanodes. Since it is a pluggable module clients can also implement their own custom authorization policy and configure it using. To configure a more fine grained policy one may configure Ranger plugin for Ozone. Clearly it is not meant for production environments. Default implementation allows every request. Ozone provides a pluggable API to control authorization of all client related operations. This is possible because both of them trust SCM signed certificates.

Datanodes use OzoneManager certificate to validate block tokens.

This certificate is used by OM and DN to prove their identities.

SCM verifies identity of DN (Datanode) or OM via Kerberos and generates a certificate.

Datanodes and OzoneManagers submits a CSR (certificate signing request) to SCM.

Below is brief descriptions of steps involved: This allows all daemons inside Ozone to have an SCM signed certificate. To enable this, SCM (StorageContainerManager) bootstraps itself as an Certificate Authority when security is enabled. CertificatesĪpart from kerberos and tokens Ozone utilizes certificate based authentication for Ozone service components. To create an S3Token user must have a S3 secret. S3Gateway creates this token for every s3 client request. It is signed by S3secret created by client. Like block tokens S3Tokens are handled transparently for clients. Client with expired block token will need to refetch the key/block locations to get new block tokens. Block token can’t be renewed explicitly by client. Block tokens are validated by Datanodes when receiving read/write requests from clients. Instead, they are handed transparently to client along with key/block locations.

Unlike delegation tokens there is no client API to request block tokens. Block tokens are created by OM (OzoneManager) when a client request involves interaction with DataNodes such as read/write Ozone keys. Block Tokensīlock tokens are similar to delegation tokens in sense that they are signed by OzoneManager. Clients can use delegation token to establish connection with OzoneManager and perform any file system/object store related operations like, listing the objects in a bucket or creating a volume etc. Token operations like get, renew and cancel can only be performed over an Kerberos authenticated connection.

Max date: Time after which token can’t be renewed.

Issue date: Time at which token was issued.

Renewer: User responsible for renewing the token.

Like Hadoop delegation tokens, an Ozone delegation token has 3 important fields: This token can be used by a client to prove its identity until the token expires. Once client establishes their identity via kerberos they can request a delegation token from OzoneManager. Ozone utilizes three types of token: Delegation token

Main motivation for using tokens inside Ozone is to prevent the unauthorized access while keeping the protocol lightweight and without sharing secret over the wire. Tokens are widely used in Hadoop to achieve lightweight authentication without compromising on security. So one way to setup identities for all the daemons and clients is to create kerberos keytabs and configure it like any other service in hadoop. Similar to hadoop, Ozone allows kerberos-based authentication. Specifically it can be configured for following security features: Starting with badlands release (ozone-0.4.0-alpha) ozone cluster can be secured against external threats.
