Security Tip #1: Strong Authentication

• Importance of strong authentication (e.g., MFA).
• Definition of multi-factor authentication (MFA):
  • Something I know (password, PIN)
  • Something I have (hardware token, phone)
  • Something I am (biometrics)
• Emphasis on phishing-resistant authentication methods:
  • Proximity-based methods (e.g., certificate cards, TPM).
  • Ranking of authentication methods:
    • Worst: text message
    • Better: authenticator apps
    • Best: passkeys and passwordless technologies.
• Importance of break glass accounts secured with physical passkeys.

Security Tip #2: Less is More

• Principle of least privilege practice.
• Grant minimum necessary permissions to identities, including human and service principles.
• Use just-in-time permissions for elevated roles.
• Emphasis on minimal connectivity between systems.
• Balance between security and business functionality (availability).

Security Tip #3: Stay Current

• Importance of timely updates and patches across all layers:
  • Hardware, firmware, operating systems, applications.
• Safe deployment practices:
  • Gradual deployment to increasing population sizes.
• Focus on maintaining availability while staying current with updates.

Security Tip #4: Protect Critical Data

• Identify critical data that cannot be replaced (state & data).
• Importance of isolated backups to prevent data loss.
• Implement Resource Guard and immutability for backup protection.
• Data governance solutions (e.g., Purview) for data discovery and classification.

Security Tip #5: Stay Informed

• Importance of awareness at all levels in the organization.
• Security practitioners need to keep updated on threats and protections.
• Educate users about key security concerns (e.g., phishing).
• Implement protective measures around users (e.g., scan emails, simulate phishing attacks).

Conclusion

• Recap of the five security tips:
  1. Strong authentication
  2. Least privilege
  3. Stay current with updates
  4. Protect critical data
  5. Stay informed
• Encouragement to utilize available Microsoft resources and security scores for further action.
