If you deployed Oracle Analytics Cloud with a public internet accessible endpoint, you can restrict incoming traffic to your service through an access control list (ACL) that contains one or more ingress rules. You can add and edit access control rules whenever you want and allow access to a public IP address, a public CIDR block range, a VCN or Oracle services.

1. In Oracle Cloud Infrastructure Console, click in the top left corner.
2. Click Analytics & AI. Under Analytics, click Analytics Cloud.
3. Select the compartment that contains the Oracle Analytics Cloud instance you're looking for.
4. Click the name of the instance you want to control access to.
5. On the Instance Details page under Network Access, click the Edit link next to the Access Control option.
   
   
6. Add or edit access control rules as required.

   You can specify the following types of rule:

   • IP Address: Select IP Address to a specific public IP address.
   • CIDR Block: Select CIDR Block to specify a range of public IP addresses using CIDR notation.
   • Service: Select Service to allow Oracle services to access your Oracle Analytics Cloud instance.

   • Virtual Cloud Network: Select Virtual Cloud Network to specify an existing Oracle Cloud Infrastructure VCN. The drop-down list shows all the VCNs in the current compartment that you have access to. If you can't see the VCN or subnet you want, check you have the required permissions. See About Public Endpoints and Access Control Rules.

     Click Change Compartment to select a VCN from a different compartment.
