🎯 Why Your Cloud Security Audit Matters
Most SMBs assume their Microsoft 365 or Google Workspace is "secure by default." After all, you're paying Microsoft and Google billions to keep you safe, right?
Wrong.
Cloud providers give you a
foundation
of security, but they don't configure the advanced protections you actually need. It's like buying a house with a basic lock - you still need to install an alarm system, security cameras, and proper access controls.
In this guide, we'll walk through the essential security audit checklist for M365 and Google Workspace that every SMB should conduct regularly.
🔐 Identity & Access Management: Your First Line of Defense
The Multi-Factor Authentication (MFA) Gap
The Problem:
Only 22% of SMBs enforce MFA across all users. Most companies leave MFA "optional" or only require it for admins.
The Risk:
- Credential stuffing attacks can compromise entire organizations
- Phishing campaigns become much more effective
- Lateral movement within your cloud environment becomes easier
The Audit Checklist:
- MFA Enforcement: Is MFA required for ALL users (not just admins)?
- Conditional Access: Are there location-based and device-based policies?
- Number Matching: Is MFA fatigue prevention enabled?
- Trusted Devices: Are there policies for known devices?
Quick Fix:
Enable MFA for all users immediately. Use conditional access to require MFA from untrusted networks.
Admin Account Review: The Hidden Danger
The Problem:
Too many users have global admin privileges, creating massive security risks.
The Risk:
- Privilege escalation if one account is compromised
- Accidental changes by inexperienced admins
- Compliance violations from excessive permissions
The Audit Checklist:
- Global Admin Count: How many users have global admin access?
- Admin Account Review: Are admin accounts regularly reviewed?
- Just-In-Time Access: Is JIT implemented for admin tasks?
- Role-Based Access: Are users assigned minimal required permissions?
Quick Fix:
Reduce global admins to 2-3 accounts maximum. Implement role-based access control (RBAC).
Password Policies: The Foundation
The Problem:
Weak password policies make MFA less effective.
The Risk:
- Brute force attacks on weak passwords
- Password reuse across multiple accounts
- Social engineering targeting weak credentials
The Audit Checklist:
- Password Complexity: Are strong password requirements enforced?
- Password Expiration: Are passwords required to change regularly?
- Password History: Are users prevented from reusing old passwords?
- Account Lockout: Are accounts locked after failed attempts?
Quick Fix:
Enforce strong password policies with 12+ characters, complexity requirements, and regular expiration.
🛡️ Data Protection & Compliance: Protecting What Matters
Data Loss Prevention (DLP): The Missing Piece
The Problem:
Sensitive data can be shared externally without restrictions, leading to compliance violations and data breaches.
The Risk:
- Accidental data leaks through email or file sharing
- Compliance violations (HIPAA, PCI DSS, etc.)
- Reputation damage from public data exposure
The Audit Checklist:
- DLP Policies: Are DLP rules configured for sensitive data?
- Data Classification: Are sensitivity labels applied to documents?
- External Sharing: Are there restrictions on external file sharing?
- Email Protection: Are emails scanned for sensitive data?
Quick Fix:
Implement DLP policies for credit card numbers, SSNs, and other sensitive data types.
Data Classification: Know What You're Protecting
The Problem:
Without proper data classification, you can't protect what you don't know exists.
The Risk:
- Over-protection of non-sensitive data (wasting resources)
- Under-protection of sensitive data (compliance violations)
- Inconsistent policies across different data types
The Audit Checklist:
- Sensitivity Labels: Are documents classified with sensitivity labels?
- Retention Policies: Are data retention policies configured?
- Encryption: Is data encrypted at rest and in transit?
- Access Controls: Are there different access levels for different data types?
Quick Fix:
Implement sensitivity labels (Public, Internal, Confidential, Restricted) and apply them consistently.
Compliance Center: Meeting Your Obligations
The Problem:
Many SMBs don't realize they have compliance obligations until it's too late.
The Risk:
- Audit failures from missing compliance controls
- Legal liability from non-compliance
- Customer trust loss from compliance violations
The Audit Checklist:
- Compliance Policies: Are relevant compliance policies active?
- Audit Logging: Is comprehensive audit logging enabled?
- Retention Policies: Are data retention policies compliant?
- Access Reviews: Are regular access reviews conducted?
Quick Fix:
Enable audit logging and implement basic compliance policies for your industry.
🚨 Threat Protection: Stopping Attacks Before They Start
Safe Links: Protecting Against Phishing
The Problem:
Phishing attacks are increasingly sophisticated and can bypass basic email filters.
The Risk:
- Credential theft from fake login pages
- Malware downloads from malicious links
- Data breaches from compromised accounts
The Audit Checklist:
- Safe Links: Is URL protection enabled for emails?
- Link Scanning: Are links scanned before users click them?
- Blocked URLs: Are known malicious URLs blocked?
- User Education: Are users trained on phishing awareness?
Quick Fix:
Enable Safe Links protection and implement user training on phishing awareness.
Safe Attachments: Stopping Malware
The Problem:
Malicious attachments can bypass traditional antivirus and infect entire organizations.
The Risk:
- Ransomware attacks from malicious attachments
- Data exfiltration from malware
- System compromise from infected files
The Audit Checklist:
- Safe Attachments: Is attachment scanning enabled?
- Sandboxing: Are suspicious attachments opened in sandbox?
- Blocked File Types: Are dangerous file types blocked?
- User Notifications: Are users notified about blocked attachments?
Quick Fix:
Enable Safe Attachments and block dangerous file types (.exe, .bat, .ps1, etc.).
Advanced Threat Protection (ATP): Enterprise-Grade Security
The Problem:
Basic security isn't enough against sophisticated attacks.
The Risk:
- Zero-day attacks that bypass traditional defenses
- Advanced persistent threats (APTs)
- Targeted attacks against your organization
The Audit Checklist:
- ATP Features: Are advanced threat protection features enabled?
- Behavioral Analysis: Is AI-powered threat detection active?
- Threat Intelligence: Is threat intelligence integrated?
- Incident Response: Are automated response actions configured?
Quick Fix:
Enable ATP features and configure automated response actions for common threats.
📊 Security Score Assessment: Measuring Your Posture
Microsoft Secure Score: Your Security Dashboard
