How to secure Microsoft Office 365 Business plans?

   The Administrator account has many privileges and control over the Office 365 environment. Hackers like to target these Administrator accounts to access the other accounts attached with the respective funds.

The Administrator should have the multi-factor authentication enabled in the report; only the essential tabs should open,n and unrelated apps and accounts should be canceled. Log out from the tab after finishing the session.

   The user can send multiple files in the attachments like word, spreadsheets, presentations, executable files, etc. Because it is not easy to identify which extension has malware, you can use Microsoft Defender for Office 36,5, including the Safe Attachment security feature.

   This feature is not enabled by default, so the Administrator needs to enable it in the Security & Compliance Center.

6. Use Message Encryption in Office

   Outlook has an outstanding feature to encrypt the incoming and outgoing email messages that the user should always use.

   When the user is sending emails, the Options tab has a feature for Permission. Choose Encrypt.
