Google Workspace is a powerful platform for collaboration, but without proper security measures, it can be vulnerable to breaches.
Implement access management best practices, like enforcing least privilege access and enabling MFA.
Effective misconfiguration management strategies include auditing sharing settings and securing admin console access.
Enhance compliance and risk management by enabling audit logging and monitoring dormant accounts.
Implement data discovery and classification best practices, such as identifying sensitive data and preventing sharing in Gmail.
Google Workspace is a robust platform that enables organizations to collaborate, communicate, and manage workflows across tools like Gmail, Google Drive, Google Docs, and more. However, without proper security configurations and monitoring, Google Workspace can become vulnerable to data breaches, misconfigurations, and compliance risks. This guide provides actionable best practices for improving both your SaaS Security Posture Management (SSPM) and Data Security Posture Management (DSPM) in Google Workspace, ensuring a secure and compliant environment.
1. Implementing Access Management Best Practices
Enforce Least Privilege Access for Google Workspace Users
Ensure users only have access to the tools and data necessary for their roles.
Example: Marketing team members should only have access to campaign folders in Google Drive, while HR teams access employee records.
Industry Example: In 2021, a European enterprise suffered a data breach when an over-permissioned user accidentally shared sensitive files with the entire organization. Regular access reviews resolved the issue. (Source)
Monitor External Sharing Permissions to Enhance Security
Limit sharing of files and folders outside the organization.
Example: Configure Google Drive settings to restrict external sharing for sensitive departments like Finance and Legal.
Industry Example: A financial services firm experienced data leakage when confidential contracts were shared externally without approval. Tightening external sharing policies and adding audits resolved the risk. (Source)
Google Workspace Security Best Practices: Monitor Eternal Sharing Permissions
Implement Multi-Factor Authentication (MFA) for Enhanced Protection
Require MFA for all Google Workspace accounts to prevent unauthorized logins.
Example: Admins should enforce MFA for all users, particularly those with elevated privileges.
Industry Example: An education institution prevented phishing attacks by mandating MFA for both students and faculty members. (Source)
Conduct Audits on Google Drive Sharing Settings Regularly
Ensure that files shared with "Anyone with the link" are identified and remediated.
Example: Flag files with overly permissive sharing settings and automatically restrict them to specific users.
Industry Example: A healthcare provider avoided HIPAA violations by auditing Google Drive for publicly shared files containing patient data and revoking access. (Source)
Secure Admin Console Access to Prevent Unauthorized Changes
Restrict admin console access to authorized users and implement logging for admin actions.
Example: Enable logging for admin actions such as user creation, role assignment, or changes to organizational units.
Industry Example: A tech company prevented unauthorized access by securing admin accounts with strict permissions and logging all configuration changes. (Source)
Monitor Third-Party App Integrations for Potential Risks
Audit all third-party apps connected to Google Workspace to minimize risks.
Example: Revoke unused or risky apps with excessive permissions, such as access to Gmail or Drive data.
Industry Example: A media company reduced its exposure to supply chain attacks by conducting quarterly reviews of connected apps and removing unused integrations. (Source)
3. Enhancing Compliance and Risk Management Measures
Enable Audit Logging and Retention for Compliance Purposes
Turn on Google Workspace audit logs to monitor user and admin activities.
Example: Enable and retain logs for activities such as file sharing, downloads, and login events for at least 1 year.
Industry Example: A government agency ensured compliance with GDPR requirements by configuring audit logging and regularly reviewing activities. (Source)
Monitor Dormant and Inactive Accounts to Mitigate Risks
Identify and deactivate unused accounts to reduce the attack surface.
Example: Automatically deactivate accounts that have been inactive for more than 60 days.
Industry Example: An enterprise IT firm minimized insider threats by deactivating dormant Google Workspace accounts after identifying them during a security audit. (Source)
Review User Groups and Organizational Units for Security
Ensure groups and organizational units (OUs) are properly configured to align with data access requirements.
Example: Restrict critical business functions like finance, HR, and legal to secure organizational units.
Industry Example: A multinational company reduced accidental data leaks by restructuring Google Workspace organizational units to align with team functions. (Source)
4. Data Discovery and Classification Best Practices
Identify and Classify Sensitive Data in Google Drive Effectively
Scan Google Drive to identify sensitive files, such as PII, PCI, or intellectual property, and apply appropriate classifications.
Example: Flag files containing customer Social Security Numbers, financial records, or internal product plans.
Industry Example: A retail company achieved PCI compliance by scanning Google Drive for unencrypted credit card information and restricting access to authorized users. (Source)
Google Workspace Security Best Practices: Strac Data Discovery that identifies and classifies sensitive data
Prevent Sharing of Sensitive Data in Gmail for Data Protection
Monitor outgoing emails for sensitive information and block unauthorized sharing.
Example: Use DLP tools to identify and block emails containing keywords such as SSNs, credit card numbers, or other sensitive data.
Industry Example: A healthcare organization prevented PHI leakage by scanning Gmail attachments for HIPAA-related data before delivery. (Source)
5. Access and Sharing Monitoring Strategies
Detect Anomalous Sharing Activity to Prevent Data Breaches
Track and flag unusual file-sharing patterns in Google Drive.
Example: Alert admins if a user shares hundreds of files externally within a short period.
Industry Example: A tech company prevented data exfiltration by identifying a departing employee who shared proprietary documents with their personal Gmail account. (Source)
Monitor Admin and Privileged User Activities for Security
Track actions taken by admins, such as bulk file deletions or permission changes.
Example: Alert the security team if an admin modifies sharing permissions for critical folders without approval.
Industry Example: A SaaS company detected and stopped malicious activity by closely monitoring admin actions across Google Workspace. (Source)
6. Proactive Threat Detection Measures
Detect Suspicious Login Behavior to Prevent Unauthorized Access
Monitor login attempts for anomalies, such as access from high-risk locations or unfamiliar devices.
Example: Alert admins if a user logs in from multiple countries within a short timeframe.
Industry Example: A financial institution blocked account takeover attempts after detecting suspicious login behavior from IP addresses in multiple regions. (Source)
Track Bulk Downloads of Sensitive Data for Data Loss Prevention
Flag large data downloads from Google Drive as they may indicate data exfiltration.
Example: Trigger an alert if a user downloads all files from a critical folder in a short time frame.
Industry Example: A healthcare company prevented a data breach by identifying and stopping a bulk download of PHI by a compromised account. (Source)
Google Workspace Security Best Practices: Strac tracks bulk downloads of sensitive data
Conclusion
Implementing these Google Workspace security best practices ensures a robust and compliant environment for collaboration and file management. By focusing on access controls, misconfiguration management, data discovery, and threat detection, organizations can significantly reduce risks and protect sensitive data.
