New in Windows security: Automatically log off suspicious users

Microsoft's Cloud App Security subscription service will boot users off the network, and out of apps and services, at the first sign of anomalous behavior. Microsoft has added rapid reaction to a year-old subscription service that will automatically shut down accounts - logging a user out of all managed apps and services, including those delivered by a third-party - at the first hint of suspicious activity. The new feature in Cloud App Security (CAS), a security service launched in August 2016, collaborates with Azure Active Directory (AAD), another subscription service, to automatically bump off users behaving unusually and shut down accounts suspected of having been hijacked. CAS is built, at least in part, on technology Microsoft acquired in 2015 when it bought the Israeli cloud security vendor Adallom for $250 million.
