Curriculum Overview: AWS Access Management and Credential Security

This curriculum provides a comprehensive roadmap for mastering identity security within the AWS ecosystem. It focuses on the transition from basic user authentication to advanced, automated credential management using AWS-native services.

## Prerequisites

Before beginning this curriculum, learners should possess:

• Cloud Fundamentals: Basic understanding of the AWS Shared Responsibility Model.
• Identity Basics: Familiarity with the concept of Users, Groups, and Roles within IAM.
• Technical Access: Experience navigating the AWS Management Console and a basic understanding of a Command Line Interface (CLI).

Layers of Identity Security

## Module Objectives

Module 1: Identity Hardening

• Enforce Complexity: Configure IAM Password Policies to require non-standard characters and minimum lengths.
• Root Isolation: Implement MFA for the root user and transition daily tasks to IAM admin users.

Module 2: Programmatic Security

• Access Key Lifecycle: Generate, use, and rotate Access Key IDs and Secret Access Keys safely.
• Eliminate Sharing: Transition from shared keys to IAM Roles for cross-account access.

Module 3: Secrets Management

• Automated Rotation: Use AWS Secrets Manager to automatically change database passwords without downtime.
• Configuration Storage: Utilize AWS Systems Manager (SSM) to store non-sensitive operational parameters.

## Success Metrics

To demonstrate mastery, students must successfully perform the following:

• Audit Readiness: Generate an IAM Credential Report and identify users with passwords older than 90 days.
• Lab Completion: Securely store a database string in Secrets Manager and retrieve it via the AWS CLI without hardcoding credentials.
• Compliance Check: Define a policy that restricts access based on IP address ranges or MFA status using Condition keys.

[!IMPORTANT] Success is not just knowing the services, but applying the Principle of Least Privilege: providing the minimum permissions necessary for a task.

## Real-World Application

• DevOps Engineer: Automating software patching and configuration management across thousands of instances using Systems Manager.
• Security Architect: Reducing the "blast radius" of a potential leak by enforcing 30-day rotation cycles for all API keys via Secrets Manager.
• Compliance Officer: Using AWS Artifact and IAM reports to prove to auditors that all administrative access is protected by MFA.

## Examples

1. Password Policy Configuration

Scenario: A financial firm requires high security.

• Definition: A set of rules defining the complexity and lifetime of user passwords.
• Example: Setting the policy to: Minimum length: 14, Require Symbols: Yes, Password Expiration: 60 Days.

2. Secrets Rotation

Scenario: An application needs to connect to an RDS database.

• Definition: The automated process of updating a credential in both the database and the storage service.
• Example: Secrets Manager updates the RDS password at 2:00 AM and simultaneously updates the encrypted value stored in its own vault so the app always fetches the current version.

3. Programmatic Access vs. Console Access

▶Click to expand: Why avoid Access Keys for EC2?

Instead of placing Access Keys on an EC2 instance, you should use IAM Roles. This allows the instance to "assume" permissions temporarily, removing the need to store long-term secrets on the server disk.
