![]() ![]() Microsoft will notify global admins of eligible Azure AD tenants this month about security defaults through an email. Customers can't request extensions beyond this date, Microsoft's Exchange Team stressed earlier this month. Now, the deadline for moving Exchange Online to modern authentication is October 1, 2022. Microsoft wanted to disable legacy authentication for Exchange Online in 2020, but that was delayed by the pandemic. So, one group of customers that won't be prompted to enable security defaults next month are Exchange Online customers still using legacy authentication. ![]() The security default roll out will come first to organizations that aren't using Conditional Access, haven't previously used security defaults, and "aren't actively using legacy authentication clients". It was also aimed at organizations using the free tier of Azure AD licensing, allowing these admins to just toggle on "security defaults" via the Azure portal. Microsoft introduced secure defaults in 2019 as a basic set of identity security mechanisms for less well-resourced organizations that wanted to boost defenses against password and phishing attacks. It was the evolution of Active Directory Domain Services in Windows 2000. "When complete, this rollout will protect an additional 60 million accounts (roughly the population of the United Kingdom!) from the most common identity attacks," says Microsoft's director of identity security, Alex Weinert.Īzure AD is Microsoft's cloud service for handling identity and authentication to on-premise and cloud apps. Today, Azure AD security defaults are used by about 30 million organizations, according to Microsoft, and over the next month Microsoft will roll out the defaults to many more organizations that will result in the defaults protecting 60 million more accounts. ![]()
