Protect Your Business from Cyber Criminals with These Top 10 Microsoft 365 Security Measures!

Updated: Apr 12, 2023

Microsoft 365 (M365) has become the go-to cloud-based productivity suite for organizations worldwide. However, with great power comes great responsibility - and in this case, that responsibility is to ensure the security of your organization's data and resources.

Fear not, fellow tech enthusiasts! We've put together a list of high-level recommendations to help you harden the security of your M365 deployment. So, buckle up and let's dive into the world of M365 security hardening!

  1. Embrace the MFA Mantra: Multi-Factor Authentication (MFA) is your digital bouncer, adding an extra layer of security to your account access. Don't let cybercriminals crash the party - make MFA mandatory.

  2. RBAC to the Future: Role-Based Access Control (RBAC) is a time-tested way to assign permissions based on roles. Keep it simple, keep it secure, and keep your users in their lanes.

  3. Least Privilege is More: Grant users and admins the minimum level of access necessary for their roles. Remember, with great power comes great potential for security breaches.

  4. Prevent Data Loss with DLP: Data Loss Prevention (DLP) policies protect sensitive info from unintended leaks and keep your secrets safe - just like your best friend.

  5. Unleash Advanced Threat Protection (ATP): Think of ATP as your digital bodyguard, detecting and protecting against a variety of cyber threats. Give phishing and malware the boot with ATP.

  6. Default to Security: Security defaults are like the express lane to baseline security. Apply them and watch your organization's security posture improve.

  7. Audit Logs: Your Digital Detective: Regularly review and monitor audit logs to track user activity and stay ahead of potential security incidents.

  8. Set Conditions with Conditional Access: Implement conditional access policies to customize access based on factors like user location, device type, and application sensitivity.

  9. Encrypt Like You Mean It: Protect sensitive data with encryption both at rest and in transit. Utilize M365's built-in features like Azure Information Protection (AIP) and S/MIME.

  10. Email Security: Spam and Phishing Be Gone: Use Exchange Online Protection (EOP) to guard against spam, malware, and phishing attempts. Keep your inbox safe and secure.

  11. Manage Mobile Madness: Implement mobile device management (MDM) and mobile application management (MAM) with Microsoft Intune or other MDM solutions to protect corporate data on mobile devices.

  12. Audit Mailboxes Like a Boss: Enable mailbox auditing to track and monitor access, keeping a watchful eye on users, delegates, and administrators.

  13. Patching: The Unsung Hero of Security: Keep all devices and software up-to-date with the latest security patches and updates. A stitch in time saves nine (or more) security headaches.

  14. Train Your Troops: Conduct security awareness training to empower your users to recognize phishing attempts, use strong passwords, and report suspicious activity.

  15. Secure Score: Your Security Fitness Tracker: Utilize Microsoft Secure Score to get personalized recommendations and insights into your security posture. Knowledge is power, so flex those security muscles!

By following these high-level recommendations, you can fortify your M365 environment and better protect your organization's data and resources. Remember, a secure M365 deployment is an ongoing process, so stay vigilant, stay informed, and stay secure!
