Key Principles of Google Workspace Management

• Single OU Membership: Each user or account belongs to only one Organizational Unit (OU), simplifying policy management.
• Multiple Group Memberships: Users can be part of multiple Groups, allowing flexible access across different OUs.
• Policy Inheritance: Policies automatically cascade from parent OUs to child OUs, ensuring consistent enforcement.
• Group-Based Access Control: Utilize Groups to manage cross-OU access for resources and SaaS applications efficiently.

Implementation Guidelines for Google Workspace and SaaS

User Account Naming Conventions

Standardized naming conventions enhance manageability and consistency across the organization.

• Regular Users:
  • Format: firstName.lastName@domain.com
  • Examples: john.smith@company.com, maria.garcia@company.com
• System Accounts:
  • Service Accounts: svc-[purpose]-[number]@domain.com
    • Examples: svc-backup-01@company.com, svc-integration-01@company.com
  • Admin Accounts: admin-[type]-[firstName.lastName]@domain.com
    • Examples: admin-super-john.smith@company.com, admin-help-maria.garcia@company.com

User Provisioning Steps

1. Primary OU Assignment: Assign users based on Department and Employment Type.
   • Path Example: Engineering Department → FTE
   • User Example: john.smith@company.com → Engineering → FTE
2. Group Assignment:
   • Primary Group: Assign to the relevant Department Group.
   • Secondary Groups: Add to Project Groups as required.
   • Security Groups: Assign based on specific access needs for SaaS applications.

Account States Management in Google Workspace

Account States Organizational Structure

Account States OU
├── Pending
│   └── For employees not yet started
└── Suspended
    └── For temporary account suspensions

‍State Management Guidelines

1. Pending Accounts:
   • Create accounts in the Pending OU with limited access.
   • Move to the appropriate Department OU upon the start date.
2. Suspended Accounts:
   • Move accounts to the Suspended OU while retaining group memberships.
   • Define suspension duration based on organizational policies.

Account State Transitions

Pending → Active Department OU → Suspended → Deleted/Archived

• Automated Transitions: Implement automation for onboarding (Pending to Active) and offboarding (Active to Suspended). Schedule account deletion or archiving post-suspension to reduce licensing costs.

Policy Management for Security and Compliance

Policy Cascade Structure

Root OU
└── Department OU
    ├── Security Baselines
    ├── Device Management Policies
    └── Employment Type OU
        ├── Access Levels
        └── License Types

‍Example Policies for Different OUs

1. Root OU Policies:
   • Enforce Multi-Factor Authentication (MFA) for all accounts to enhance security.
   • Disable External Sharing to comply with data protection regulations.
2. Pending OU Policies:
   • Override MFA settings to disabled for minimal access during onboarding preparation.
3. Drive Management External OU:
   • Enable External Sharing for controlled collaboration with external partners.

Security Framework: Implementing Role-Based Access Control (RBAC)

Access Control Matrix for SaaS Applications

• User Addition & Approval:
  • Managers can add or approve users directly in the app or through Security Group Assignment.
  • Utilize managers as approvers for access requests to streamline the process.
• Automated Access with RBAC:
  • Automate access provisioning based on user roles or departments.
  • Implement RBAC to reduce manual provisioning and accelerate onboarding.

Employee Lifecycle Management in Google Workspace

Onboarding Process

1. Create User in Pending OU:
   • Add new users with restricted access to the Pending OU.
2. Move to Appropriate Department OU:
   • Schedule the move to the relevant Department OU on the start date.
3. Assign to Groups:
   • Add users to Department and Project Groups as necessary.
4. Configure SaaS Access:
   • Set up Single Sign-On (SSO), assign to security groups, and provision licenses.

Offboarding Process

1. Account Access:
   • Suspend the Google Workspace account.
   • Move the account to the Suspended OU.
   • Revoke access to all SaaS applications.
2. Data Management:
   • Transfer ownership of Google Drive files.
   • Archive or transfer email data as per compliance requirements.
3. Cleanup:
   • Remove the user from all Groups.
   • Release any assigned resources like licenses or devices.
4. Finalize:
   • Schedule the account for deletion or archiving to reduce billing and licensing costs.

Conclusion

Efficient management of Google Workspace and SaaS applications is critical for organizational security, compliance, and productivity. By leveraging Organizational Units, Groups, and automated policies, you can streamline employee lifecycle management and enforce robust security measures.
