The OCI Security and Compliance Blueprint

An audit ready security architecture for Oracle Cloud Infrastructure, built so the controls you run every day are the same evidence your auditors ask to see.

Summary

What this paper covers.

Most OCI tenancies were built to get a workload live, and the security architecture arrived later, one policy and one exception at a time. That works until the first serious audit, when SOC 2, ISO 27001, PCI DSS, or DORA assessors start asking for evidence the estate was never designed to produce. This paper sets out a reference security architecture for OCI that is audit ready by construction, covering tenancy isolation, compartment and IAM design, Cloud Guard and Security Zones, network segmentation, encryption and key management with OCI Vault, and the logging that turns daily operations into audit evidence.

It is written for the people who have to defend the architecture, not just build it. Every control in the blueprint is mapped to the frameworks auditors actually test against, so the same design answers the security question and the compliance question at once. The guidance reflects patterns we use across our own OCI engagements, and it is architecture guidance, not a compliance certification.

Inside

What is inside.

  • A reference OCI security architecture in four layers, from tenancy to workload.
  • A compartment and IAM design that survives growth instead of collapsing into policy sprawl.
  • How to deploy Cloud Guard, Security Zones, and the Audit service as a detective control plane.
  • Network segmentation with NSGs, private endpoints, and the Bastion service, with no public exposure by default.
  • Where customer managed keys in OCI Vault actually matter for audits, and where they do not.
  • A mapping of the blueprint to SOC 2, ISO 27001, PCI DSS, and DORA expectations.
Audience

Who it is for.

  • CISOs and security leaders accountable for cloud risk on OCI.
  • Security architects designing or remediating an OCI tenancy.
  • Compliance and risk leads preparing for SOC 2, ISO 27001, PCI DSS, or DORA assessments.
  • Platform teams who run OCI day to day and have to produce the evidence.
