How does OCI ensure resource isolation and security?

In Oracle Cloud Infrastructure (OCI), security lists and network segments play a crucial role in ensuring resource isolation and security. Security lists act as virtual firewalls for your resources, controlling inbound and outbound traffic at the subnet level. They allow users to define rules that permit or deny access based on IP addresses, protocols, and ports. This level of granularity helps protect resources from unauthorized access and attack.

Network segmentation further enhances security by isolating different workloads within Virtual Cloud Networks (VCNs). By creating separate subnets for different application tiers or environments (like production, development, and testing), organizations can limit potential attack surfaces and enforce stricter security measures.

When properly configured together, security lists and network segments help prevent unauthorized access to resources and facilitate effective traffic management, contributing significantly to the overall security posture of OCI.

While other options touch on aspects related to resource management or scaling, they do not specifically address the mechanisms for ensuring isolation and security within OCI, making security lists and network segments the most pertinent focus for this question.
