Security zone can be configured using Ranger. Ranger administrators can divide resources of each component into multiple security zones where Ranger administrators set security policies for specified resources in the zones to facilitate management. Policies defined in a security zone apply only to resources in the zone. After service resources are allocated to the security zone, the access permission policies for the resources in the non-security zone do not take effect. The administrator of a security zone can set policies only in the security zone that the administrator belongs to.

Adding a Security Zone

Log in to the Ranger web UI as the Ranger administrator rangeradmin. For details, see Logging In to the Ranger Web UI.

Click Security Zone. On the zone list page, click

to add a zone.

Configuring Permission Policies in a Security Zone

Log in to the Ranger management page as the Ranger administrator of a security zone.
Select a security zone from the Security Zone drop-down list in the upper right corner of the Ranger home page to switch to the permission view of the security zone.
Click the permission plug-in name of a component. The page for security access policy list of the component is displayed.

NOTE:

In the policy list of each component, the default items generated by the system are automatically inherited to the security zone to ensure the permissions of some default users or user groups in the cluster.
Click Add New Policy and configure resource access policies for related users or user groups based on the service scenario plan.

In this example, a policy that allows user test to access the /testzone/test directory is configured in the security zone.

The following access policies are examples for different components:
After the policies are added, wait for about 30 seconds for them to take effect.
NOTE:
- Policies defined in a security zone apply only to resources in the zone. After service resources are allocated to the security zone, the access permission policies for the resources in the non-security zone do not take effect.
- To configure access policies for resources outside the current security zone, click Security Zone in the upper right corner of the Ranger homepage to exit the current security zone.
