Curriculum Overview: Centralized AWS Account Deployment & Management

This curriculum is designed for security architects and engineers aiming to master Domain 6: Security Foundations and Governance of the AWS Certified Security - Specialty (SCS-C03) exam. It focuses on the strategic deployment of multi-account environments using industry-standard governance frameworks.

Prerequisites

Before beginning this curriculum, learners should possess the following foundational knowledge and tools:

• AWS Global Infrastructure: A solid grasp of Regions, Availability Zones (AZs), and Edge Locations.
• IAM Fundamentals: Understanding of Users, Groups, Roles, and the difference between long-term credentials and temporary security tokens.
• Technical Environment:
  • An active AWS Account (Management Account).
  • AWS Command Line Interface (CLI) installed and configured.
• Conceptual Knowledge: Familiarity with Infrastructure as Code (IaC) principles and basic JSON/YAML syntax for policy authoring.

Module Breakdown

This curriculum is structured into five core modules, progressing from foundational organizational structures to advanced guardrail implementation.

Learning Objectives per Module

Module 1: AWS Organizations

• Objective: Design and deploy a hierarchical account structure using Organizational Units (OUs).
• Outcome: Ability to create a multi-account strategy that supports policy inheritance and consolidated billing.

Module 2: AWS Control Tower

• Objective: Implement a "Landing Zone" based on AWS best practices.
• Outcome: Utilize the Account Factory (vending machine) to automate the provisioning of new accounts with pre-configured security baselines.

Module 3: Policy Governance

• Objective: Author and enforce Service Control Policies (SCPs) to establish security guardrails.
• Outcome: Effectively restrict the maximum available permissions across an organization, preventing even root users from performing unauthorized actions (e.g., disabling CloudTrail).

Module 4: Centralized Security Management

• Objective: Configure Delegated Administrator accounts for security services.
• Outcome: Shift security operational tasks away from the Management Account to a dedicated Security/Audit account to minimize the blast radius.

Module 5: Identity & Root Protection

• Objective: Develop a strategy for managing root user credentials and "break-glass" procedures.
• Outcome: Secure the most privileged identity in the cloud using hardware MFA and centralized monitoring.

Success Metrics

To demonstrate mastery of this curriculum, learners must be able to:

1. Enforce Compliance: Successfully prevent a member account from deleting a production S3 bucket using an SCP.
2. Automate Provisioning: Deploy a new, pre-hardened AWS account through the Control Tower Account Factory in under 30 minutes.
3. Audit Visibility: Centralize all CloudTrail logs from 5+ accounts into a single, encrypted S3 bucket in a Log Archive account.
4. Zero-Trust Root Management: Demonstrate a functional MFA-protected root user strategy where the root credentials are never used for daily administration.

Real-World Application

In a corporate environment, this strategy transforms cloud management from a manual, error-prone process into a scalable Governance as Code engine.

[!IMPORTANT] The "Vending Machine" Concept: In enterprise IT, developers often wait weeks for new environments. By implementing the strategies in this curriculum, you create an Account Factory. This allows the business to "vend" a fully compliant, pre-audited AWS account in minutes, ensuring speed without sacrificing security.

[!WARNING] Never run production workloads in your Control Tower Management Account. This account should be reserved strictly for organization-wide management and billing tasks to minimize risk.
