                                   |
                                   v
                       +-----------------------+
                       | Zero Trust & RBAC     |
                       | (Least Privilege &    |
                       | Context-Aware Access) |
                       +-----------------------+

Enforce Mandatory 2-Step Verification (2SV) Across All Accounts

Multi-Factor Authentication (MFA) neutralizes over 99% of automated account attacks.

• Enforce Security Keys: Deploy FIDO2 hardware security keys or phone-based prompt authentication for high-risk accounts (Super Admins, Finance, C-Suite).

• Eliminate Weak Methods: Disable SMS-based verification and voice call codes, which remain vulnerable to SIM swapping attacks.

• Define Grace Periods: Establish a mandatory 2SV enforcement window for newly onboarded employees to prevent unprotected account gaps.

Implement Strict Password & Login Policies

• Set minimum password lengths (at least 14–16 characters) emphasizing passphrases over complex short strings.

• Disable password reuse across account cycles and prevent long-term credential caching.

• Utilize Single Sign-On (SSO) integrations via SAML 2.0 to centralize authentication through trusted identity providers.

Restrict Super Admin Privileges via Role-Based Access Control (RBAC)

• Apply the Principle of Least Privilege (PoLP) by assigning dedicated Custom Admin Roles rather than granting full Super Admin privileges.

• Maintain a minimum of two and a maximum of five active Super Admin accounts to prevent single points of failure while minimizing the attack surface.

• Enforce dedicated, separate administrative accounts (e.g., admin.john@company.com) for management tasks instead of using daily operational emails.

2. Advanced Email Security & Domain Authentication

Email represents the dominant vector for phishing, spear-phishing, and Business Email Compromise (BEC). A complete Google Workspace Security Checklist must secure incoming and outgoing mail transport.

Enforce Complete Email Authentication (SPF, DKIM, DMARC)

Ensure proper DNS configuration to maintain domain reputation and prevent unauthorized brand impersonation:

1. SPF Setup: Specify Google’s mail servers (v=spf1 include:_spf.google.com ~all) along with verified third-party sending services.

2. DKIM Signing: Generate 2048-bit DKIM keys inside the Google Admin Console and publish the TXT records to your DNS authority.

3. DMARC Policy Enforcement: Move progressively from monitoring (p=none) to quarantine (p=quarantine) and ultimately to complete rejection (p=reject) with automated RUA/RUF reporting.

Configure Advanced Phishing and Malware Protection

Within the Google Admin Console under Apps > Google Workspace > Gmail > Safety, activate high-grade protection rules:

• Enable protection against spoofing of domain names and employee names.

• Quarantine incoming emails displaying suspicious attachments, unauthenticated domain origins, or encrypted scripts.

• Enable Enhanced Pre-Delivery Scanning to execute deep inspection on incoming attachments prior to user inbox delivery.

• Enforce BIMI (Brand Indicators for Message Identification) to attach verified brand logos to legitimate outbound emails, increasing receiver trust.

3. Data Loss Prevention (DLP) & Drive Sharing Controls

Data leaks often originate from accidental internal oversights. An effective Google Workspace Security Checklist outlines granular controls for file storage and external sharing.

          +-------------------------+-------------------------+
                                    |
                                    v
                  +-----------------------------------+
                  | Secure Shared Drives              |
                  | - Restricted External Access      |
                  | - Organizational Unit (OU) Rules  |
                  +-----------------------------------+

Restrict External Google Drive File Sharing

• Disable public link sharing (“Anyone with the link can view”).

• Restrict external file sharing exclusively to whitelisted, trusted target domains.

• Enforce a default restriction preventing Viewers and Commenters from downloading, printing, or copying files containing sensitive intellectual property.

• Automatically revoke external access privileges after a defined expiration timeframe (e.g., 30 days).

Deploy Automated Data Loss Prevention (DLP) Rules

• Construct automated scanning rules targeting Personally Identifiable Information (PII), payment card industry data (PCI-DSS), financial records, and confidential credentials.

• Configure DLP actions to automatically warn users, block external sharing attempts, or alert IT administrators when violations occur.

• Restrict Google Form submissions from requesting sensitive credential formats or unverified external file uploads.

Structure Organizational Units (OUs) & Shared Drives

• Avoid storing primary business data inside personal employee drives; transition assets into centrally managed Shared Drives.

• Limit Shared Drive administrative rights so that project members cannot alter root security configurations or move sensitive items to unmanaged locations.

• Implement custom trust rules tailored to distinct Organizational Units (OUs) to enforce strict controls on sensitive departments like Finance and HR.

4. Endpoint Management & Mobile Security Controls

As remote and hybrid work models expand, managing mobile devices and laptops accessing cloud data forms a critical component of any Google Workspace Security Checklist.

                   +----------------------------------+

| - Screen Lock & Passcode Rules   |         | - OS Version Enforcements        |
+----------------------------------+         +----------------------------------+

Enforce Google Endpoint Management (MDM)

• Advanced Mobile Management: Require employee devices (iOS & Android) to register under corporate management before accessing company data.

• Mandatory Screen Locks: Enforce minimum 6-digit numeric passcodes or biometric authentication across managed devices.

• Device Encryption: Require disk-level encryption for all connected mobile devices and laptops.

• Selective Remote Wipe: Configure capabilities to remotely wipe corporate data from lost, stolen, or compromised devices without altering personal user data.

Implement Context-Aware Access (CAA) Rules

Context-Aware Access enables Zero Trust security architecture by validating user context during login attempts:

• Block access to Google Workspace apps if the user operates an outdated, unpatched operating system.

• Restrict sensitive Admin Console access to designated corporate IP subnets or verified corporate networks.

• Mandate compliance checks verifying that endpoint security tools remain active before granting file access.

5. Third-Party App Management & API Governance

Unchecked third-party OAuth integrations present backdoor entry points into company environments. This section of the Google Workspace Security Checklist mitigates risks associated with malicious or vulnerable cloud extensions.

Audit and Restrict OAuth API Access

• Periodically audit third-party applications connected to your workspace environment via Security > Access and data control > API controls.

• Set baseline policies to Block all unconfigured third-party apps from accessing Google Workspace data.

• Limit API access levels for high-risk scopes (e.g., full Gmail read/write permissions or complete Google Drive modification rights).

Whitelist Only Vetted Google Workspace Marketplace Apps

• Restrict individual employees from installing unapproved add-ons directly from the Marketplace.

• Maintain an internal IT-approved Marketplace whitelist containing vetted applications that meet organization-wide compliance standards.

• Conduct semi-annual reviews of granted scopes for existing integrations to revoke permissions from inactive software providers.

6. Continuous Monitoring, Auditing & Incident Response

A static security configuration requires ongoing maintenance. The final phase of our Google Workspace Security Checklist focuses on continuous visibility, threat detection, and incident remediation.
