How to Better Secure Your Microsoft 365 Environment

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

Double-Check Employees' Privileges 
Administrative accounts in a Microsoft 365 environments have elevated privileges, which are valuable attacker targets and should only be used for administrative tasks. Microsoft advises admins to keep a separate user account for regular, non-admin use to limit privileged access.
Admin accounts should be configured with MFA and used carefully. Before using an admin account, an employee should close unrelated browser sessions and apps, including personal email accounts; after completing admin tasks, they should log out of the browser session.
Accounts with privileged permissions are oftentimes more than just those assigned the 'Global Administrator' role, says McWhirt. He encourages admins to review and validate the scope of accounts assigned privileged permissions and roles within Microsoft 365, and to use separate cloud-only accounts for managing the Microsoft 365 tenant.
'It's not uncommon to provide too many administrative accounts when quickly adopting a new technology,' says Hass. 'These permissions are rarely restricted later on.' Following the rule of least privilege, he adds, is 'extremely important.'
Privileged accounts used to access and manage Microsoft 365 resources should only be allowed to connect from trusted locations, FireEye experts write in a whitepaper on hardening Microsoft 365 in the wake of SolarWinds. These locations usually consist of public IP address blocks managed by the business.
Before enabling this policy, experts warn admins to test in Report-Only mode to ensure that the configuration works as expected. This prevents accounts from being locked out of Microsoft 365, they say.
