A quick #securitytip on how to block password-protected attachments in emails.

If you have #Microsoft #Defender for #Office365 licenses, you can use the technology called Safe Attachments. Safe Attachments do advanced scanning of attachments through so called detonations, where these attachments are run on a test environment and what the file does when it is run is monitored.

If an email contains a password-protected attachment, then these detonations cannot take place. In the Safe Attachments settings, you can set what should happen if the scan couldn't complete for some reason, which is exactly the case with the password-protected attachment. In this case, it is recommended to set the email to be blocked. #email #mdo #cybersecurity #bes
