Lab Architecture

Objective

Create a secure and repeatable OCI foundation to demonstrate Oracle Deep Data Security for AI, analytics, and enterprise application workloads.

Logical Design

  Bastion --> PE

Components

Layer	Component	Purpose
Network	VCN, private subnet, NSGs	Isolate database and application flows.
Database	Private Autonomous Database	Run lab schemas, policies, and tests.
Security	Deep Data Security	Enforce authorization by user, role, and context.
Keys	Optional OCI Vault	Enable customer-managed keys when required.
Operations	Optional compute bastion	Controlled administrative access when required.
Evidence	SQL output, logs, screenshots	Support technical validation and demos.

Security Principles

No public database exposure.
Access through private subnet and NSG rules.
mTLS required.
Secrets kept out of Git.
Minimum privileges for OCI resources.
Data policies versioned as SQL.
Preventive controls first; auditing for evidence and investigation.

What Terraform Does Not Configure

Terraform provisions infrastructure. Fine-grained configuration such as users, data roles, data grants, and test data stays under scenarios/ so each lab can be installed and reset without recreating the OCI environment.
