Restricting access to OIC instances

Restrict the networks that have access to your Oracle Integration instance by configuring an allowlist (formerly a whitelist). Only users from the specific IP addresses, Classless Inter-Domain Routing (CIDR) blocks, and virtual cloud networks that you specify can access the Oracle Integration instance.

For the Oracle Integration instance, configure the allowlist when you create the instance or after creating the instance.

Option 1 for Configuring Allowlists: Restrict Access to Oracle Integration Using the Self-service Allowlist Capabilities

In this scenario, you restrict access to Oracle Integration using an allowlist. The allowlist restricts access based on the following parameters:

• Single IP address
• Classless Inter-Domain Routing (CIDR) block (that is, an IP address range)
• Virtual Cloud Network Oracle Cloud ID (VCN OCID)

Additionally, your organization might have a service gateway. The service gateway lets your virtual cloud network (VCN) privately access Oracle Integration without exposing the data to the public internet.

Only the specified IP addresses and VCN OCIDs can access Oracle Integration. Users and systems accessing Oracle Integration from listed VCNs have full access.

Advantages

• Easy setup! You can configure your allowlist in just a few minutes, without having to create a custom endpoint.
• All traffic is supported, including REST, SOAP, and other internet traffic.
