The diagram illustrates a Secure Remote Worker Environment architecture on AWS. This setup allows remote workers to securely access key business applications and data. Here's a detailed explanation of the components and their interactions:

How It Works (Step-by-Step):

1. User Access to Amazon WorkSpaces:

• Users on their devices (laptops, desktops, or tablets) connect to their Amazon WorkSpaces virtual desktop by:
  • Providing their username, password, and Multi-Factor Authentication (MFA) code.
• Amazon WorkSpaces provides a virtual desktop infrastructure (VDI) for remote access.

2. Authentication Against Directory Service:

• The Amazon WorkSpaces authentication gateway verifies user credentials using AWS Directory Service.
• The Directory Service integrates with Active Directory to validate credentials and enforce organizational policies.

3. MFA Code Validation:

• The MFA code entered by the user is validated using a RADIUS server, such as OneLogin, to ensure a second layer of security.

4. Connection to WorkSpaces Desktop:

• Once authenticated, users are connected to their Amazon WorkSpaces desktop environment, which provides a secure and managed workspace.

5. Access to Core Systems and Files:

• From the WorkSpaces desktop, users can access:
  • Applications and systems running on Amazon EC2 instances (virtual servers).
  • Shared files hosted on Amazon FSx for Windows File Server, which provides file storage optimized for Windows-based applications.

6. Group Policy Enforcement:

• Group policies configured in Active Directory prevent certain activities (e.g., printing to local printers or copying data to unapproved locations). This ensures compliance with organizational security policies.

7. DNS Resolution Through Route 53:

• The Domain Controller DNS forwards DNS queries to the Amazon Route 53 VPC DNS Resolver, which resolves domain names to IP addresses.
