Demystifying OCI Network Security: Understanding Security Lists
Introduction: Oracle Cloud Infrastructure (OCI) offers a robust and secure environment for hosting your applications and databases. As an Oracle Apps DBA, understanding the intricacies of OCI's networking and security features is crucial. In this blog post, we'll dive into one essential component of OCI networking - Security Lists. Security Lists in OCI: Security Lists are a fundamental part of OCI's security model. They act as virtual firewall rules for your Virtual Cloud Network (VCN), allowing you to control traffic flow to and from resources within your network. Key Concepts: Ingress and Egress Rules : Security Lists consist of both ingress (incoming) and egress (outgoing) rules. These rules define which traffic is allowed and which is denied.
