DOES OUTLOOK FOR OFFICE 365 USE OAUTH INSTALL
You must take into account any 3rd party applications/devices using SMTP/IMAP to send or access your accounts, as these system may still be using Legacy Protocols and need to be migrated. However they are left on my default in Office 365.ĭisabling theses protocols and blocking Basic Authentication on your organization’s cloud user accounts is a good measure as well as our recommendation to Federate your Office 365 with Practice Protect. Modern Outlook connections to Office 365 no longer use these protocols.
This is because legacy authentication protocols like POP, SMTP, IMAP, and MAPI can’t enforce MFA, making them preferred entry points for adversaries attacking your organization. Attackers targeting accounts using legacy IMAP/POP/SMTP protocols in order to brute-force the accounts using common variations on usernames and passwords exposed in large credentialed dumps.įor MFA and Practice Protect polices to be effective, legacy authentication needs to be blocked at the Office 365 level.
