    - Configuring Policy-Based Security
      Starting in HPE Ezmeral Data Fabric 6.2.0 (EEP 7.0.0), HPE Ezmeral Data Fabric supports Policy-Based Security. Policy-Based Security is a mechanism that enables administrators to create security policies for simplified data management. Administrative users can create and manage security policies through the control system, maprcli, REST API, Hadoop and Linux commands, and Java APIs.
      - Setting Global Configuration Options for Policy-Based Security
        The CLDB stores global configuration settings for Policy-Based Security. Before creating security policies, an administrator must designate a master security policy cluster through the cldb.pbs.global.master option.
      - Granting Security Policy Permissions
        Permissions define which administrative users can create, view, and modify security policies. Administrators set the permissions on security policies through cluster-level and security policy-level ACLs.
      - Creating a Security Policy
        Describes how to create a security policy using the Control System, CLI, and REST API.
      - Changing the State of a Security Policy
        The security policy state indicates whether users can apply a security policy to data objects and whether the system enforces the ACEs set in the security policy. An administrator can change the state of a security policy through the allowtagging and accesscontrol parameters when creating or modifying a security policy from the maprcli or equivalent REST API comands.
      - Tagging Data Objects with Security Policies
        Once security policies are configured (with tagging enabled), permitted users can associate the security policies with data objects through the Control System, CLI, and REST API. A data object can be associated with one or multiple security policies.
        Tagging Volumes, Directories, and Files with Security Policies
        Associate security policies with data objects in the file system, including volumes, directories, and files. Associate up to sixteen security policies with a data object in the file system.
        Tagging JSON Tables, Column Families, and Fields with Security Policies
        Associate security policies with HPE Ezmeral Data Fabric Database JSON tables, column families, and fields.
      - Security Policy Java APIs
        You can create, retrieve, and remove security policies, and associate security policies with a data object using file system APIs.
      - Enforcing Security Policies at the Volume-Level
        Describes how to set enforcement modes for security policies at the volume-level.
      - Troubleshooting Security Policies
        This topic describes problems that you may encounter when creating and using security policies. It includes recommendations on how to troubleshoot and resolve problems.
      - Policy-Based Security Quick Reference

Tagging Data Objects with Security Policies

Once security policies are configured (with tagging enabled), permitted users can associate the security policies with data objects through the Control System, CLI, and REST API. A data object can be associated with one or multiple security policies.

ATTENTION

Verify that the security policy state is set to allow tagging. By default, a security policy has allowtagging=false and accesscontrol=Disarmed when created. See Changing the State of a Security Policy.

Supported Data Objects

The following table lists the data objects in the data-fabric platform that users can tag with security policies:

file system	HPE Ezmeral Data Fabric Database
Volumes Directories Files	JSON tables JSON table column families JASON table fields NOTE If you upgrade your data-fabric cluster to version 6.2.x from a pre-6.2.0 version, you can apply security policies to existing tables if Policy-Based Security is enabled. See Policy-Based Security Quick Reference.

Permissions Required to Tag Data Objects

Users must have the required permissions to tag security policies to data objects. Permission requirements vary depending on the data-fabric platform core component.

The following table lists the users that can tag data objects in the data-fabric filesystem and database:

file system HPE Ezmeral Data Fabric Database

Owner of the data object
Data Fabric administrator (typically mapr)
Superuser (root)

The superuser cannot tag filesystem objects when the cldb.reject.root flag is set.

Data Fabric administrator (typically mapr)
User with ACE administrative access (adminaccessperm permission)

The following sections describe how to tag data objects in the file system and HPE Ezmeral Data Fabric Database with security policies
