How to Better Secure Your Microsoft 365 Environment

Security experts offer Microsoft 365 security guidance as more attackers target enterprise cloud environments.
9 of 10

Strengthen Email Security Settings
Microsoft 365 comes with malware protection built in; however, admins can take additional steps to block malware and ransomware by configuring their mail settings to block attachments with file types commonly used for malware or ransomware.
The processes for creating both mail flows are outlined in detail on Microsoft's website. Admins essentially create two rules: the first warns users before opening file attachments that include macros; the second blocks file types that could contain ransomware or other malicious code.

In the same post are steps to prevent auto-forwarding, a measure to defend against attackers who gain access to an employee's email account. This helps ensure intruders can't leverage their access to exfiltrate emails or gain further access in an employee's account, Microsoft says.
Office Message Encryption, also included in Microsoft 365, lets employees send and receive encrypted email messages between people inside and outside the business. When sending mail with Office Message Encryption, employees have the option to encrypt, or add 'do not forward' to a message.
