Provides details on how to configure network access with access control rules or using a private endpoint and describes the secure client connection options. Also describes how to enable support for TLS connections (require mutual TLS only or allow both mutual TLS and TLS authentication).

• Configuring Network Access with Access Control Rules (ACLs)
  Specifying an access control list blocks all IP addresses that are not in the ACL list from accessing the database. After you specify an access control list, the Autonomous Database only accepts connections from addresses on the access control list and the database rejects all other client connections.
• Configure Network Access with 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 a private endpoint in an existing database that uses a public endpoint. This allows you to keep all traffic to and from your database off of the public internet.
• Use Zero Trust Packet Routing on Autonomous Database
  Oracle Cloud Infrastructure Zero Trust Packet Routing (ZPR) protects sensitive data from unauthorized access through intent-based security policies that you write for resources, such as an Autonomous Database on a private endpoint, that you assign security attributes to.
• Update Network Options to Allow TLS or Require Only Mutual TLS (mTLS) Authentication on Autonomous Database
  Describes how to update the secure client connection authentication options, Mutual TLS (mTLS) and TLS.
