Oracle Cloud Infrastructure OCI Gen-2 Cloud Security – Part III (Networking)

In my previous blog posts, I have discussed the generic security concepts and Identity and Access Management in OCI. This part of the series discusses OCI Networking Service. Its concepts and best practices for securing networks in OCI.

High-throughput and reliable networking is fundamental to public-cloud infrastructure that delivers compute and storage services at scale. As a result, Oracle has invested significant innovation in Oracle Cloud Infrastructure networking to support requirements of enterprise customers and their workloads. Oracle Cloud Infrastructure regions have been built with a state-of-the-art, non-blocking Clos network that is not over-subscribed and provides customers with a predictable, high-bandwidth, low latency network. The data centers in a region are networked to be highly available and have low-latency connectivity between them.

In this post, I will go into depth on the components that make up the networking layer, and the security rules which can be applied to them.

Oracle Cloud Infrastructure OCI Gen-2 Cloud Security – Part II (Identity and Access Management)

In my previous blog post Oracle Cloud Infrastructure OCI Gen-2 Cloud Security – Part I , I have discussed the seven pillars of information security upon which Oracle Cloud Infrastructure OCI (Oracle Gen-2 Cloud) is built. The cloud shared security and responsibility model was discussed along with the concepts such as Regions, Availability Domains and Fault Domains. This part discusses the Identity and Access Management for OCI. It provides authentication and authorisation for all the OCI resources and services.

An enterprise can use single tenancy shared by various business units, teams, and individuals while maintaining the necessary security, isolation, and governance, and this post will go into the concepts involved in this.
