Configure Security Rules for the Network

If your instance communicates with other resources in Oracle Cloud or on the Internet, create or update the security lists for your target Oracle Cloud Infrastructure network.

A security list is assigned to subnets within your virtual cloud network (VCN). It includes ingress and egress rules that specify the types of traffic allowed in and out of the instances within the subnet. You can update an existing security list, or create a new one and assign it to a subnet.

You might need to create security rules if your Oracle WebLogic Server for OCI instance communicates with external resources, including these Oracle WebLogic Server resources:

• JavaMail Session
• Foreign Java Naming and Directory Interface (JNDI) Provider
• Foreign Java Message Service (JMS) Server
• Messaging Bridge
• Store-and-Forward
• WebLogic Diagnostic Framework (WLDF) REST Action

See Security Lists in the Oracle Cloud Infrastructure documentation.
