How to Better Secure Your Microsoft 365 Environment

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

Consider CASB
Cloud access security broker (CASB) tools have grown to become an essential part of data protection as businesses more heavily depend on cloud applications, Hevesi says. 
'CASB has been one of those tools that, as you adopt cloud, becomes one of those mission critical tools,' he explains. Microsoft Cloud App Security (MCAS) is a CASB that operates across multiple clouds and helps IT and security teams gain more visibility into data so they can detect threats. Gartner advises Microsoft 365 admins to deploy MCAS or a third-party CASB for more visibility.
The CASB is there to double-check DLP and data classification, and catch actions like sharing highly sensitive files. If an employee suddenly starts sharing critical documents, or starts syncing their OneDrive to another machine, a CASB tool will pick up on it.
'It's that analysis of what's happening deeper into Microsoft 365, or whatever cloud apps you're using -- that becomes key,' Hevesi says of the CASB's role. Admins benefit from a single place where they can view activity across cloud applications.

'Now that you have one cloud application, let's make sure you get all the other applications underneath the CASB so you have a single pane of glass to protect all your cloud applications and you can understand the risk across that,' Hevesi says. An IT security admin must know the risk across cloud apps, and a CASB can help them do that.
