With the evolving landscape of digital threats, maintaining robust security in Office 365 is more critical than ever. This office 365 security checklist, based on insights from various expert sources, outlines essential security measures for Office 365.
1. Strengthen Password Policies
Implement strict password protocols to ensure strong, unique passwords for all users, minimizing the risk of unauthorized access.
2. Enforce Multi-Factor Authentication
MFA is crucial for all user accounts, particularly for administrators. It adds an additional security layer, significantly reducing the risk of compromised accounts.
3. Disable Legacy Authentication Protocols
Protocols like POP, IMAP, and SMTP are vulnerable to attacks. Disabling them and moving to modern authentication methods enhances security.
4. Utilize Advanced Threat Protection (ATP)
ATP helps in defending against sophisticated cyber threats, including malicious links and attachments in emails and documents.
5. Anti-Phishing and Anti-Spam Configuration
Implement comprehensive anti-phishing and anti-spam measures to protect against email-based threats.
6. Cybersecurity Training for Staff
Regular training sessions for employees on cybersecurity best practices can significantly reduce the risk posed by human error.
7. Implement Azure Information Protection
This tool encrypts sensitive Office documents and emails, restricting access to authorized individuals only.
8. Activate Azure Identity Protection
Detect and respond to unusual user behavior and sign-in risks with Azure Identity Protection to prevent potential breaches.
9. Control Data Access with Customer Lockbox
Customer Lockbox provides control over Microsoft support engineers’ access to your data, ensuring transparency and security.
10. Secure Application Ecosystem in the Cloud
Cloud App Security is vital for protecting applications within the Office 365 suite, ensuring overall cloud security.
11. Use Unified Audit Log (UAL) for Monitoring
Enable UAL for thorough monitoring and investigation of activities within Office 365 for potential threats or policy violations.
12. Prevent Sensitive Data Leakage
Set parameters to detect and block sharing of sensitive information such as personal and financial data.
13. Configure SharePoint and OneDrive Security
Adjust settings to protect data shared via SharePoint and OneDrive, utilizing data loss prevention strategies.
14. Leverage Microsoft Secure Score
Use Microsoft Secure Score to evaluate and improve your organization’s security posture against potential threats.
