Describes the options for restricting network access to your Autonomous Database by specifying access control rules or using a virtual cloud network (private access with a private endpoint).

• About Network Access Options
  Provides an overview of the network access options available when you provision or clone Autonomous Database.
• Overview of Restricting Access with ACLs
  When you select the network access Allow secure access from anywhere option when you provision or clone an instance, you can restrict network access by defining an Access Control List (ACL). You can also add, update, or remove an ACL for an active instance.
• Overview of Private Endpoints
  You can specify that Autonomous Database uses a private endpoint inside your Virtual Cloud Network (VCN) in your tenancy. You can configure a private endpoint during provisioning or cloning your Autonomous Database, or you can switch to using private endpoints in existing databases that use public endpoints. This allows you to keep all traffic to and from your Autonomous Database off of the public internet.
